Product Description
ZYS High Quality Chrome Steel Drawn Cup Needle Roller Bearings HK3012
The needle bearing is roller bearing with a cylindrical roller, which is both thin and long with respect to its diameter. In spite of the smaller crosssection, the bearing still has a high load bearing capacity. The needle bearing is equipped with thin and long rollers (roller diameter D ≤ 5mm, L/D ≥ 2.5, L means the length of the roller), therefore its radial structure is compact. When the inner diameter size and load capacity are the same as those of other types, the outer diameter is the smallest, which is particularly suitable for a support structure in which the radial installation size is limited.
Structure type
This type of bearing has a radial needle and thrust full of ball, or with a thrust ball, or with a thrust cylindrical roller, or with the angular contact ball into one, can withstand unidirectional or two way axial load. Can also be
designed according to the user’s specific structural requirements.

Maintenance and Lubrication Requirements for Cup Bearings
Cup bearings, like other types of bearings, require proper maintenance and lubrication to ensure their longevity and reliable performance. Here are the key considerations:
1. Regular Inspection: Periodically inspect cup bearings for signs of wear, damage, or misalignment. This visual inspection can help identify issues early.
2. Lubrication: Most cup bearings require lubrication to reduce friction and dissipate heat. The type of lubrication and frequency of re-lubrication depend on the bearing’s design and application. Consult the manufacturer’s recommendations for specific guidelines.
3. Contamination Control: Preventing contaminants like dirt, dust, and moisture from entering the bearing is crucial. Seals and shields help protect cup bearings from contaminants and should be regularly inspected for damage.
4. Re-greasing: In applications that require lubrication, re-greasing should be performed at regular intervals to maintain the proper lubrication film. Over-greasing can lead to overheating, while under-greasing can cause premature wear.
5. Correct Installation: Proper installation is essential to ensure cup bearings operate as intended. Follow the manufacturer’s installation guidelines, including torque specifications for locking nuts.
6. Temperature Management: Be aware of operating temperature limits. High temperatures can degrade lubricants, while low temperatures can affect bearing performance. Choose the appropriate lubricant for the expected temperature range.
7. Relubrication Holes: Some cup bearings have relubrication holes or grooves for easy maintenance. Make use of these features if available.
8. Handling and Storage: Store cup bearings in a clean, dry environment. Handle them with care to avoid damage to the bearing surfaces or seals.
Proper maintenance and lubrication practices are essential to maximize the service life and performance of cup bearings in various industrial and mechanical applications.
Usage of Cup Bearings in Heavy-Duty and Industrial Machinery
Yes, cup bearings are commonly employed in heavy-duty and industrial machinery applications due to their durability and load-carrying capabilities. These applications include:
1. Construction Equipment: Cup bearings are used in heavy construction machinery such as excavators, cranes, bulldozers, and concrete mixers to support radial and axial loads in harsh working environments.
2. Mining Equipment: Mining machinery, like crushers, conveyors, and drilling rigs, rely on cup bearings to handle the extreme loads and abrasive conditions found in mining operations.
3. Agricultural Machinery: Farming equipment, including tractors and combines, uses cup bearings for various components, providing reliable operation in dusty and challenging farming conditions.
4. Material Handling: Industrial material handling equipment, like forklifts, conveyors, and packaging machinery, depends on cup bearings for smooth movement and load support.
5. Heavy Manufacturing: In manufacturing settings, cup bearings are integrated into machinery such as presses, stamping equipment, and injection molding machines to facilitate precision movement and support heavy loads.
6. Automotive Manufacturing: Cup bearings play a crucial role in automotive manufacturing processes, ensuring the functionality of robotic arms, conveyors, and assembly line equipment.
7. Marine and Offshore: Machinery used in marine and offshore applications, including winches, cranes, and propulsion systems, rely on cup bearings to withstand saltwater exposure and heavy loads.
8. Power Generation: In power plants, cup bearings are used in generators, turbines, and other machinery to support rotational elements, demonstrating their ability to handle high temperatures and forces.
These examples illustrate the versatility and resilience of cup bearings, making them a valuable choice for various heavy-duty and industrial machinery applications.
Types of Cup Bearings for Various Applications
Cup bearings, also known as tapered roller bearings, come in several types to suit different applications. These variations are designed to accommodate specific load capacities, axial and radial forces, and operational conditions. Here are some common types:
1. Single-Row Tapered Roller Bearings: These cup bearings consist of a single row of tapered rollers between the inner and outer rings. They are suitable for applications with moderate radial and axial loads, such as in wheel hubs, transmissions, and differentials in automobiles.
2. Double-Row Tapered Roller Bearings: Double-row cup bearings have two rows of tapered rollers and can handle higher radial and axial loads compared to single-row bearings. They are often used in heavy machinery and gearboxes that require increased load-carrying capacity.
3. Four-Row Tapered Roller Bearings: Four-row cup bearings are designed for extremely heavy radial and axial loads. They are common in rolling mills, where they support the massive rolls used for metal shaping and processing. These bearings can withstand high forces and offer exceptional load-carrying capabilities.
4. Precision Tapered Roller Bearings: Precision cup bearings are manufactured to very tight tolerances, ensuring high accuracy and smooth operation. They are used in applications where precision, such as in machine tool spindles and aerospace components, is critical.
5. Matched Tapered Roller Bearings: Matched cup bearings consist of two tapered roller bearings with pre-set clearances and axial play. They are often used in pairs to support axial thrust in both directions. This type is common in machine tool spindles and automotive wheel bearings.
6. Custom Tapered Roller Bearings: Manufacturers can produce custom cup bearings to meet specific application requirements. These can include variations in size, load capacity, and other design parameters tailored to a particular application.
The choice of cup bearing type depends on the specific demands of the application, load requirements, and operating conditions. Proper selection ensures optimal performance and longevity in various industries, from automotive to industrial machinery.
