Product Description

Needle bearings have a large surface area that is in contact with the bearing outer surfaces compared to ball bearings. Additionally there is less added clearance . The typical structure consists of a needle cage which orients and contains the needle rollers, the needle rollers themselves, and an outer race(sometimes housing itself).

 

Radial needle bearings are cylindrical and use rollers parallel to the axis of the shaft. Thrust needle bearings are flat and use a radial pattern of needles.

 

Deatils :

 

1.Material:Bearing steel

 

2.Cage :F1 Carbon steel , nylon or palstic
