KOYO 32056JR Tapered Roller Bearings

Single-row tapered roller bearings are the most basic and widely used, consisting of a cone assembly and a cup. Timken patented the first in 1898 and today offers the world's widest variety in inch and metric sizes.

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
