We deals with Tapered Roller Bearing featured with a cup and cone assembly. The cup is comprised of the outer ring and the cone assembly consists of inner ring, rollers, and cage. These 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. Pairs of tapered roller bearings are used in Car and Vehicle wheel bearings where they must cope simultaneously with large vertical (radial) and horizontal (axial) forces. Tapered roller bearings are commonly used for moderate speed, heavy duty applications where durability is required.
