With a large catalogue range to choose from,  tapered roller bearings are also customizable to match your specific speed, load, contamination, temperature or vibration conditions.

 Tapered roller bearings feature a cup and cone assembly. The cup is comprised of the outer ring and the cone assembly consists of inner ring, rollers, and cage. This bearing construction accommodates combined loads and provides low friction during operation. By adjusting one single row tapered roller bearing against a second tapered roller bearing and applying a preload, a rigid bearing application can be achieved.

 tapered roller bearings are also made to Explorer class.  Explorer combines our expertise in bearing design, tribology, metallurgy, lubrication and manufacturing.  Explorer tapered roller bearings are typically used in bearing solutions where there is a need to increase performance, reduce friction or increase power density in applications
