Tapered roller bearings consist of four basic components including: the cone (inner ring), the cup (outer ring), tapered rollers, and a cage (roller retainer). The cone, cup and rollers carry the load while the cage spaces and retains the rollers on the cone. The cone, rollers and cage components of our tapered roller bearings are referred to as the cone assembly. Individual cup and cone components of our tapered roller bearings are available as well as the complete assembly. In addition, CHIK offers a variety of configurations to our tapered roller bearings such as single-row, double-row and four-row.

Tapered Roller Bearing Material

While other materials may be available, typically, tapered roller bearings are made of high carbon chrome steel due to their expected performance.
