Product features and applications of crossed tapered roller bearings

The precision can reach P4 level.

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

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

The rolling element rolls purely during movement, so the limit speed is much higher than that of crossed cylindrical roller bearings.

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

The design is compact and requires a small installation space.

These characteristics make it very suitable for occasions 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, precision circular indexing tables for machine tools, 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.
