Double row

Product Introduction

JOJI super-precision cylindrical roller bearings feature the following:

High-speed capability
High radial load carrying capacity
High rigidity
Low friction
Low cross-sectional height

Therefore, these bearings are particularly well-suited for machine tool spindles where the bearing arrangement must support heavy radial loads and high speeds while also providing high rigidity.
JOJI super-precision single-row cylindrical roller bearings offer higher speed performance than double-row bearings, which are better suited for carrying heavier loads.
