High precision

The accuracy can reach P4 level.

High rigidity

This series of bearings are all preloaded, and the preload size can be adjusted to achieve optimal rigidity.

High load capacity

It can withstand axial load, radial load, overturning moment, and has high anti-overturning stiffness.

high speed

The rolling elements perform pure rolling during motion, so the limiting speed is much higher than that of crossed cylindrical roller bearings.

low friction

The friction torque is much lower than that of crossed cylindrical roller bearings, and the starting torque is low.

Compact design

The design is compact and requires little installation space.

These characteristics make it very suitable for applications where space is limited, the center of gravity of the rotating mass is required to be as low as possible, and high speed requirements are required. For example, machine tool precision circular indexing tables, vertical and horizontal boring machines, vertical grinders, rotary surface grinders, vertical lathes, large gear hobbing machines, turrets, large telescopes (radio, optical), rotating cameras, industrial robots, etc.
