Ball Bearing
Timken's wheel end system is a self-retained, integrated package bearing featuring active sensing technology that offers design flexibility and bolt-on simplicity. This hub assembly improves stiffness and brake performance, reduces weight and envelope size, lowers assembly costs and reduces warranty claims.


  • Integrated raceway and hub increases stiffness as much as 30 % over conventional systems. Also eliminates the discrete race variables between the bearing and hub, providing a closer preload setting range.
  • Narrow overall package width and reduced radial section thickness lowers unsprung weight, improving vehicle maneuverability and fuel efficiency.
  • Features a pre-sealed, pre-greased and pre-set bearing package design with integrated sensing technology for anti-lock braking systems, total traction control and vehicle dynamics systems.
  • Hub-forming technology reduces strain on components and the costs associated with purchased parts and labor. Also allows for communization between driven and non-driven designs.
  • Fully serviceable wheel speed sensor (where applicable) is internally mounted and protected from road hazards, debris and potential damage.
