Product Description

Needle roller bearings contain many slender rollers with a length 3 to 10 times their diameter. Therefore, the ratio of the bearing outside diameter to the inscribed circle diameter is small, and they have a rather high radial load capacity. There are numerous types available, and many have no inner rings. The drawn-cup type has a pressed steel outer ring and the solid type has a machined outer ring. There are also cage-and-roller assemblies without rings. Most bearings have pressed steel cages, but some are without cages.
Needle roller bearings have a high load carrying capacity in addition to their low cross-section and stiffness. They are especially suitable for bearing arrangements where radial space is limited because needle roller bearings only carry pure radial load and can not limit the axial displacement of shaft relative to the housing. It is important to ensure that inner ring axis and outer ring axis must be aligned during mounting the bearings.

Product Description

ACTIVE-POWER INDUSTRIES Linear Needle Roller Bearing China Factory CSK17 2RS Drawn Cup Needle Roller Bearing

Product Description

Needle bearings are roller bearings with cylindrical rollers that are thin and long relative to their diameter. Such rollers are called needle rollers. Despite having a small cross-section, the bearing still has a high load-bearing capacity. Needle roller bearings are equipped with thin and long rollers (roller diameter D≤5mm, L/D≥2.5, L is the length of the roller), so The radial structure is compact, and its inner diameter size and load capacity are the same as other types of bearings, and its outer diameter is the smallest, especially suitable for support structures with limited radial installation dimensions.

Depending on the application occasion, a bearing without an inner ring or a needle roller and cage assembly can be selected. At this time, the journal surface and the housing hole surface matched with the bearing are directly used as the inner and outer rolling surfaces of the bearing. In order to ensure the load capacity and running performance As with bearings with rings, the hardness, machining accuracy, and surface quality of the raceway surface of the shaft or housing hole should be similar to the raceway of the bearing ring. This kind of bearing can only bear radial load

In addition to those listed in the catalog, bearings that can be used for general engineering, such as open-type drawn cup needle roller bearings (1), closed-type drawn cup needle roller bearings
(2), needle roller bearing with inner ring
(3) and needle roller bearings without inner ring/needle roller bearings without inner ring and a cage
(4), with cage and without cage filled with needle roller bearings

A combined needle roller bearing is a bearing unit composed of radial needle roller bearing and thrust bearing components. It has a compact structure, small size, high rotation accuracy, and can withstand a certain axial load while bearing a high radial load. The product structure is diverse, widely adaptable, and easy to install. Combined needle roller bearings are widely used in various mechanical equipment such as machine tools, metallurgical machinery, textile machinery, and printing machinery, and can make the mechanical system design very compact and smart

Thrust bearings consist of thrust cage assemblies with needle rollers or cylindrical rollers or balls and thrust washers. Needle rollers and cylindrical rollers are held and guided by thrust cages. When used with different series of DF thrust bearing washers, many different combinations are available for bearing configurations. Due to the selection of high-precision cylindrical rollers (needle rollers) to increase the contact length, this bearing can obtain high load capacity and high rigidity in a small space. Another advantage is that if the surface of the adjacent part is suitable for the raceway surface, the gasket can be omitted, which can make the design compact. The cylindrical surfaces of the needle rollers and cylindrical rollers used in DF thrust needle roller bearings and thrust cylindrical roller bearings are Modified face to reduce edge stress and increase service life

Contribution of Cup Bearings to Smooth Operation and Reduced Friction

Cup bearings play a crucial role in ensuring the smooth operation of machinery while minimizing friction. Their design and functions contribute to this in several ways:

  • Reduced Friction: Cup bearings are designed to minimize friction between moving parts. Their rolling elements, such as balls or rollers, reduce contact surfaces and enable smooth, low-friction movement. This reduces energy consumption and heat generation in the machinery.
  • Load Distribution: Cup bearings distribute loads evenly across their rolling elements. This even load distribution prevents excessive stress on specific points and ensures that the machinery operates smoothly without experiencing undue wear or damage.
  • Alignment Tolerance: Cup bearings can accommodate misalignment to some degree. This ability to handle minor misalignments ensures that even in less-than-ideal conditions, the machinery can continue to operate smoothly and efficiently.
  • Minimized Wear: The rolling elements and races of cup bearings are often made from materials with excellent wear resistance. This minimizes wear and extends the service life of the bearing and the machinery in which it is used.
  • Reduced Heat Generation: The low friction and efficient load distribution of cup bearings result in reduced heat generation during operation. This is particularly important in high-speed machinery where excessive heat can lead to premature wear and reduced efficiency.

Overall, cup bearings contribute to the efficient and smooth operation of machinery by reducing friction, ensuring even load distribution, and providing tolerance for misalignment. These factors are essential for minimizing wear, extending the lifespan of the machinery, and maintaining high performance.

Eco-Friendly Aspects of Cup Bearing Materials

Cup bearing materials can have eco-friendly or sustainable aspects depending on the material chosen and its recyclability or environmental impact:

1. Stainless Steel: Stainless steel is known for its corrosion resistance, which can extend the lifespan of cup bearings and reduce the need for replacements. This longevity can contribute to sustainability by minimizing the disposal of worn-out bearings.

2. Recyclability: Many cup bearing materials, such as steel and bronze, are highly recyclable. At the end of their useful life, these materials can be melted down and reused, reducing the demand for new raw materials and energy consumption.

3. Reduced Lubrication: Some cup bearings are designed for extended periods of maintenance-free operation due to self-lubrication or special coatings. This can reduce the consumption of lubricants and the disposal of used oils, promoting eco-friendliness.

4. Non-Toxic Materials: Materials used in cup bearings are typically non-toxic and do not pose environmental or health hazards. This ensures that their manufacture and disposal do not harm ecosystems or human health.

5. Sustainable Sourcing: Manufacturers often focus on responsibly sourcing materials, ensuring they come from suppliers who adhere to sustainable practices, including reforestation, waste reduction, and energy efficiency.

When selecting cup bearings for a specific application, considering the eco-friendliness of the chosen material is essential. Manufacturers and suppliers may also provide information on the sustainability practices associated with their bearing materials.

Components of a Cup Bearing Assembly and Their Roles

A cup bearing assembly consists of several components, each with a specific role in its operation:

1. Cup (Outer Ring): The cup, often referred to as the outer ring, is a hardened steel component with a precisely machined raceway. It serves as the outer race and provides structural support for the bearing. The cup’s role is to maintain the proper distance and alignment between the rollers.

2. Cone (Inner Ring): The cone, or inner ring, is another hardened steel component. It has a matching raceway that fits with the cup’s raceway. The cone serves as the inner race and contains the rolling elements. Its role is to maintain proper alignment and spacing of the rolling elements.

3. Tapered Rollers: Tapered rollers are the rolling elements that transmit the loads and facilitate smooth rotation. They are arranged between the cup and cone and are designed with a tapered shape to distribute loads evenly along the raceways, reducing the risk of edge loading and premature wear.

4. Cage (Retainer): In some cup bearing assemblies, a cage or retainer is used to maintain the spacing and orientation of the rollers. The cage ensures that the rollers do not come into direct contact with each other, reducing friction and wear while promoting smooth rolling.

5. Lubrication: Proper lubrication is crucial for the efficient operation of cup bearings. Lubricant, often grease or oil, reduces friction, dissipates heat, and minimizes wear. It also helps prevent corrosion and extends the bearing’s service life.

6. Seals and Shields: In many cup bearing applications, seals and shields are employed to protect the bearing’s internal components from contaminants and moisture. Seals create a barrier to prevent the entry of foreign particles, while shields provide limited protection while allowing some ventilation.

7. Bearing Housing: The bearing assembly is often mounted within a bearing housing, which secures it in place and aligns it with the rotating shaft. The housing provides support and ensures proper axial and radial alignment of the cup bearing.

All these components work together to facilitate the smooth and reliable operation of a cup bearing, handling various loads while minimizing friction and wear, thereby extending the bearing’s lifespan and contributing to the efficiency of the machinery it serves.

cup bearing

Contribution of Cup Bearings to Smooth Operation and Reduced Friction

Cup bearings play a crucial role in ensuring the smooth operation of machinery while minimizing friction. Their design and functions contribute to this in several ways:

  • Reduced Friction: Cup bearings are designed to minimize friction between moving parts. Their rolling elements, such as balls or rollers, reduce contact surfaces and enable smooth, low-friction movement. This reduces energy consumption and heat generation in the machinery.
  • Load Distribution: Cup bearings distribute loads evenly across their rolling elements. This even load distribution prevents excessive stress on specific points and ensures that the machinery operates smoothly without experiencing undue wear or damage.
  • Alignment Tolerance: Cup bearings can accommodate misalignment to some degree. This ability to handle minor misalignments ensures that even in less-than-ideal conditions, the machinery can continue to operate smoothly and efficiently.
  • Minimized Wear: The rolling elements and races of cup bearings are often made from materials with excellent wear resistance. This minimizes wear and extends the service life of the bearing and the machinery in which it is used.
  • Reduced Heat Generation: The low friction and efficient load distribution of cup bearings result in reduced heat generation during operation. This is particularly important in high-speed machinery where excessive heat can lead to premature wear and reduced efficiency.

Overall, cup bearings contribute to the efficient and smooth operation of machinery by reducing friction, ensuring even load distribution, and providing tolerance for misalignment. These factors are essential for minimizing wear, extending the lifespan of the machinery, and maintaining high performance.

cup bearing

Comparison of Cup Bearings with Other Bearing Types

Cup bearings, also known as tapered roller bearings, differ from other bearing types like ball bearings and roller bearings in several ways:

1. Load Capacity: Cup bearings are designed to handle both radial and axial loads, making them suitable for applications with combined forces. Ball bearings primarily handle radial loads, while roller bearings, including cup bearings, can manage both radial and axial loads.

2. Tapered Design: Cup bearings have a tapered design, which helps distribute loads more evenly, reducing the risk of damaging the bearings. Ball bearings have a different internal structure with small, spherical rolling elements, while roller bearings have cylindrical or tapered rollers.

3. Precision and Accuracy: Ball bearings, especially precision ball bearings, offer high levels of accuracy and low friction, making them suitable for applications where precise movement is essential. Cup bearings can provide precision but are typically used in applications with moderate to heavy loads.

4. Lubrication: Lubrication requirements can vary among bearing types. Cup bearings typically require adequate lubrication to operate efficiently. Ball bearings may need less lubrication due to their low friction design.

5. Versatility: Ball bearings and roller bearings come in various configurations, making them versatile for different applications. Cup bearings are primarily used in applications where tapered rollers are advantageous, such as automotive wheel hubs and gearboxes.

6. Specialized Applications: Some applications may benefit from specialized bearings like ball screws with ball bearings for high precision linear motion or spherical roller bearings for applications that require misalignment compensation.

The choice between cup bearings, ball bearings, and roller bearings depends on the specific needs of the application, including the type and magnitude of loads, operating conditions, and precision requirements. Each bearing type has its advantages and limitations, making proper selection essential for optimal performance and longevity.

Components of a Cup Bearing Assembly and Their Roles

A cup bearing assembly consists of several components, each with a specific role in its operation:

1. Cup (Outer Ring): The cup, often referred to as the outer ring, is a hardened steel component with a precisely machined raceway. It serves as the outer race and provides structural support for the bearing. The cup’s role is to maintain the proper distance and alignment between the rollers.

2. Cone (Inner Ring): The cone, or inner ring, is another hardened steel component. It has a matching raceway that fits with the cup’s raceway. The cone serves as the inner race and contains the rolling elements. Its role is to maintain proper alignment and spacing of the rolling elements.

3. Tapered Rollers: Tapered rollers are the rolling elements that transmit the loads and facilitate smooth rotation. They are arranged between the cup and cone and are designed with a tapered shape to distribute loads evenly along the raceways, reducing the risk of edge loading and premature wear.

4. Cage (Retainer): In some cup bearing assemblies, a cage or retainer is used to maintain the spacing and orientation of the rollers. The cage ensures that the rollers do not come into direct contact with each other, reducing friction and wear while promoting smooth rolling.

5. Lubrication: Proper lubrication is crucial for the efficient operation of cup bearings. Lubricant, often grease or oil, reduces friction, dissipates heat, and minimizes wear. It also helps prevent corrosion and extends the bearing’s service life.

6. Seals and Shields: In many cup bearing applications, seals and shields are employed to protect the bearing’s internal components from contaminants and moisture. Seals create a barrier to prevent the entry of foreign particles, while shields provide limited protection while allowing some ventilation.

7. Bearing Housing: The bearing assembly is often mounted within a bearing housing, which secures it in place and aligns it with the rotating shaft. The housing provides support and ensures proper axial and radial alignment of the cup bearing.

All these components work together to facilitate the smooth and reliable operation of a cup bearing, handling various loads while minimizing friction and wear, thereby extending the bearing’s lifespan and contributing to the efficiency of the machinery it serves.

Comparison of Cup Bearings with Other Bearing Types

Cup bearings, also known as tapered roller bearings, differ from other bearing types like ball bearings and roller bearings in several ways:

1. Load Capacity: Cup bearings are designed to handle both radial and axial loads, making them suitable for applications with combined forces. Ball bearings primarily handle radial loads, while roller bearings, including cup bearings, can manage both radial and axial loads.

2. Tapered Design: Cup bearings have a tapered design, which helps distribute loads more evenly, reducing the risk of damaging the bearings. Ball bearings have a different internal structure with small, spherical rolling elements, while roller bearings have cylindrical or tapered rollers.

3. Precision and Accuracy: Ball bearings, especially precision ball bearings, offer high levels of accuracy and low friction, making them suitable for applications where precise movement is essential. Cup bearings can provide precision but are typically used in applications with moderate to heavy loads.

4. Lubrication: Lubrication requirements can vary among bearing types. Cup bearings typically require adequate lubrication to operate efficiently. Ball bearings may need less lubrication due to their low friction design.

5. Versatility: Ball bearings and roller bearings come in various configurations, making them versatile for different applications. Cup bearings are primarily used in applications where tapered rollers are advantageous, such as automotive wheel hubs and gearboxes.

6. Specialized Applications: Some applications may benefit from specialized bearings like ball screws with ball bearings for high precision linear motion or spherical roller bearings for applications that require misalignment compensation.

The choice between cup bearings, ball bearings, and roller bearings depends on the specific needs of the application, including the type and magnitude of loads, operating conditions, and precision requirements. Each bearing type has its advantages and limitations, making proper selection essential for optimal performance and longevity.

Contribution of Cup Bearings to Smooth Operation and Reduced Friction

Cup bearings play a crucial role in ensuring the smooth operation of machinery while minimizing friction. Their design and functions contribute to this in several ways:

  • Reduced Friction: Cup bearings are designed to minimize friction between moving parts. Their rolling elements, such as balls or rollers, reduce contact surfaces and enable smooth, low-friction movement. This reduces energy consumption and heat generation in the machinery.
  • Load Distribution: Cup bearings distribute loads evenly across their rolling elements. This even load distribution prevents excessive stress on specific points and ensures that the machinery operates smoothly without experiencing undue wear or damage.
  • Alignment Tolerance: Cup bearings can accommodate misalignment to some degree. This ability to handle minor misalignments ensures that even in less-than-ideal conditions, the machinery can continue to operate smoothly and efficiently.
  • Minimized Wear: The rolling elements and races of cup bearings are often made from materials with excellent wear resistance. This minimizes wear and extends the service life of the bearing and the machinery in which it is used.
  • Reduced Heat Generation: The low friction and efficient load distribution of cup bearings result in reduced heat generation during operation. This is particularly important in high-speed machinery where excessive heat can lead to premature wear and reduced efficiency.

Overall, cup bearings contribute to the efficient and smooth operation of machinery by reducing friction, ensuring even load distribution, and providing tolerance for misalignment. These factors are essential for minimizing wear, extending the lifespan of the machinery, and maintaining high performance.

1. Advanced Materials: The development of new materials, such as advanced ceramics and high-performance polymers, has increased bearing durability and resistance to extreme conditions.

2. Enhanced Seals and Shields: Modern cup bearings feature improved sealing technologies that provide better protection against contamination, moisture, and other environmental factors.

3. Lubrication Systems: Some cup bearings now incorporate advanced lubrication systems, including automatic lubrication units, to ensure consistent and optimal lubrication levels.

4. Smart Bearings: IoT (Internet of Things) and sensor technology have enabled the creation of “smart” cup bearings that can monitor their own performance, providing real-time data on conditions and wear.

5. Customization: Manufacturers offer more customization options, allowing customers to tailor cup bearings to their specific application requirements.

6. Improved Load Ratings: Advancements in design and materials have increased the load-carrying capabilities of cup bearings, expanding their utility in heavy-duty applications.

7. Sustainable Practices: Bearing manufacturers are increasingly adopting eco-friendly materials and production processes, contributing to sustainability efforts.

These innovations have expanded the range of applications for cup bearings and have made them more reliable, efficient, and environmentally friendly. As technology continues to evolve, we can expect further improvements in cup bearing performance and capabilities.

Load-Carrying Capacity and Load Ratings of Cup Bearings

Cup bearings are designed to carry both radial and axial loads, and their load-carrying capacity is a critical factor in their performance. Load ratings for cup bearings are specified to help users understand their capabilities:

1. Radial Load Capacity: The radial load capacity of a cup bearing refers to its ability to support loads that are perpendicular to the shaft’s axis. This capacity is determined by factors such as the type of bearing, size, material, and design. Manufacturers provide radial load ratings in pounds or newtons to indicate the maximum radial load that a cup bearing can handle under ideal conditions.

2. Axial Load Capacity: The axial load capacity pertains to the cup bearing’s ability to support loads parallel to the shaft’s axis. Like radial load capacity, axial load capacity is specified by manufacturers and given in pounds or newtons. The design and construction of the bearing determine its axial load rating.

3. Combined Load Capacity: Cup bearings can handle combined radial and axial loads. Manufacturers specify the combined load rating to inform users about the maximum combined load, both radial and axial, that the bearing can support without premature failure. This rating is essential when the application involves varying loads or moments acting on the bearing.

It’s crucial to select cup bearings with load ratings that exceed the expected loads in the application. Factors like operating speed, temperature, lubrication, and misalignment can influence the effective load-carrying capacity of the bearing. Properly matching the bearing’s load ratings to the application’s requirements ensures reliable and long-lasting performance.
