needle roller bearings

Needle roller bearings have a large carrying capacity and are suitable for supporting structures with limited installation dimensions. The journal surface is hardened as a rolling surface, and the bearing is pressed into the seat hole with a press fit, so it does not need to be axially positioned.

Before installation, the bearing should be injected with the right amount of grease. Generally, BK type bearings should not be re-lubricated after assembly. It is used for bearings without journal projections. The end face seal acts as a seal and can withstand small axial movements.
