Bearing Service – the Key to Reliability

All forms of transmissions, transfer cases and differentials use anti-friction bearings to support moving components, reduce parasitic power losses and maintain the parts in their correct positions for long-term reliability. The most-common bearings we see in manual transmissions, transfer cases and differentials fall into several categories of design. Each type will have different design criteria as for operational speed and the ability to handle axial (thrust) and radial loads.
