ETC EVO Tapered roller bearings

Tapered roller bearings (TRBs) utilize rolling elements that are shaped like a truncated cone, and are constructed so that all tapered surfaces converge at a common apex point on the bearing centerline to yield true rolling motion. Tapered roller bearings are generally used in lower speed, high load applications and are capable of absorbing radial and/or axial loads. The internal angles may be designed to tailor the bearing to the loading demands of a specific application.
