Needle Roller Bearing - Separable Cage, Without Inner Ring, RNAF Series

Volume Discount

IKO

In this series, IKO needle roller bearings are combined with thrust roller bearings to receive thrust loads. Their axial load ratings are greater than those of bearings that are combined with thrust ball bearings. Also, plastic deformation of the rolling contact surfaces under load is minimal. Furthermore, the thrust bearing section is finished to high accuracy, and therefore high rotational accuracy is obtained in the case of both vertical and horizontal shafts.

Like the needle roller bearings with thrust ball bearing, this series also includes bearings with a dust cover and bearings with an inner ring.
