Cylindrical roller bearing for backup roll of multi high rolling

The bearing used for multi-stage backup roll can be installed in a multiple number on a single shaft because it distributes the rolling force.

For this reason, not only sufficient rigidity and durability but also high accuracy are necessary.

Bearings superior in the accuracy and service life are supplied with the JTEKT's original cored hardening method adopted for the steel material and crouching surface treatment.
