Frictional torque reduced

They are said to be able to achieve a reduction in frictional torque of up to 50% compared to conventional tapered roller bearings. The dynamic load rating (load carrying capacity) of the X-life bearing has increased by 20%, with a resulting minimum 70% improvement in the basic nominal operating life of the bearing.

As well as improving the performance and energy efficiency of the bearing, the X-life tapered units are reported to provide benefits in terms of a reduced design envelope, weight and friction.
