Timken's Generation 3 wheel end system is a self-retained, integrated package bearing featuring active sensing technology that offers design flexibility and bolt-on simplicity. Generation 3 improves stiffness and brake performance, reduces weight and envelope size, lowers assembly costs and reduces warranty claims.

 

Design Attributes

• Integrated raceway and hub increases stiffness as much as 30 percent 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 is internally mounted and protected from road hazards, debris and potential damage.

 

Applications

• Wheels for light trucks and sport utility vehicles

 

The Generation 3 is a self-retained unit (see illustration below) that reduces component count and simplifies assembly. Instead of conventional wheel-end-designs that use a thread and nut mechanism, the bearing and wheel are retained by the inherent design of the unit.

 

The forming process creates a single integrated hub and bearing unit that can be bolted directly onto the knuckle of light trucks and sport utility vehicles.

 

Increase system stiffness and integrity hold the bearing setting better than conventional designs – reducing runout and improving brake system life and vehicle performance. And, the design flexibility offered by Generation 3 allows for more robust components, which means a better overall wheel-end system and more satisfied drivers.
