Product Description:
Definition of Needle roller bearings:
Needle roller bearings are a type of roller bearings and are
classified as either radial or thrust depending on the direction of
the load they support. Needle roller bearings include bearings
whose rollers slightly exceed the size range of needle rollers as
stipulated by ISO. Needle roller bearings include drawn cup and
solid radial bearings, as well as application-specific cam
followers, roller followers. Thrust bearings include thrust needle
bearings. Although not classified as a rolling bearing, there is
also a spherical sliding bearing that supports radial and axial
loads.
