Needle bearing

Needle roller bearings use long and narrow cylindrical rollers that sometimes exceed JIS/ISO size ranges. They are categorized as thrust or radial bearings based on which load direction they support. Radial types include drawn-cup and solid types, as well as application-specific track rollers (cam and roller followers). Thrust needle and thrust roller bearings respond to axial load needs.

Needle roller thrust bearings feature cage & needle roller assemblies with a surface-hardened cage made of two precision-pressed steel plates. The rollers are retained securely in the cage to maintain smooth rotation even under large axial loads. These bearings are so small that they can easily replace conventional thrust washers in the same mounting space.
Different configurations are available, including standalone units, integrated raceway units, or units with different race thicknesses, to match mounting conditions around the bearing.

Feature

1.Space-saving design

2.Achieves a compact design with the same thin cross-section height as a thrust washer.

3.Using the gear side surface as the raceway allows for even greater equipment downsizing.

4.High rigidity and wear resistance

5.The cage is surface-hardened to provide high rigidity and resistance to wear.

Applications

1.Planetary gears in automobiles, constant mesh gearboxes, torque converters

2.Axial piston pumps, compressors
