The Timken Co has developed the Wheel Boss single-source wheel-end system for standard trailer axles with a capacity of 22,500 pounds. Each component of the system supports longer life, greater fuel efficiency, and reduced maintenance costs when teamed with Timken tapered roller bearings.

The Wheel Boss adjusting nut has a locking method that provides accurate bearing setting and superior retention on the spindle. Because the adjusting nut locks tight to the spindle, instead of a tang in the keyway, the spindle thread life is improved. A wear-resistant surface maintains the precise pre-load setting during operation.

Timken's patented HDL grease seal circulates grease within the bearing, keeping contamination out and lubrication in. The flanged outer seal case provides visual confirmation that the seal is fully seated. Another benefit of this grease seal is that it vents internal pressure and does not require a vented hubcap. Timken includes a nonvented hubcap that eliminates water and debris infiltrating the wheel end.
