Timken Wheel-Pac™
The Timken Wheel-Pac™ bearing is a pre-set, pre-greased, pre-sealed integrated bearing assembly that provides outstanding wheel end performance for commercial vehicle trucks and trailers. We customized Wheel-Pac™ to suit the truck builder’s preferred hub design.

Design Attributes:
Pre-set, pre-greased and pre-sealed bearing package eliminates the need for manual bearing adjustment and features fewer components, simplifying installation and maintenance. Features a reduced bearing setting range that reduces runout, increases assembly stiffness and provides better friction control for increased system life. Design optimizes weight and packaging for high power density – greater performance in a smaller package. Additional design options include through hardened or case carburized steel (for improved debris resistance), greased, super-sealed or oiled lubrication options, and anti-lock braking systems ring integration.

Applications:
Commercial vehicle truck and trailer wheel ends
