Description of needle roller bearing

HK series single row needle bearing is a kind of needle roller bearing with very small radial section size. It mainly consists of a thin wall stamping outer ring with needle roller and cage assembly. These types of bearings are favored in space-constrained industrial applications due to their compact structure and high load capacity.

Physical design of needle roller bearing

1.The stamping outer ring process is used to achieve a balance between lightweight and high rigidity, and the outer diameter tolerance is controlled within ±0.01mm
2.Single row needle roller arrangement design, axial bearing capacity of radial load up to 30%

Performance benefits of needle roller bearing

1.Limit speed: grease lubrication up to 15,000rpm, oil lubrication up to 25,000rpm
2.Wear resistance: surface HRC58-62 heat treatment, life than ordinary bearings increased by 40%

Application scenarios of needle roller bearing

1.Automotive industry: starter one-way clutch (such as HK28.2x35.2x14.8-3RS model)
2.Power tools: Motor spindle support (HK0408TN and other mini models)
3.Textile Machinery: High speed spindle bearing (HK0612 series)
