• Simplified, compact drive train design saves capital equipment costs
• Pre-set internal clearance facilitates ease and accuracy of the assembly
• Pre-loaded bearing designed for superior stiffness to manage motion of the main shaft and rotor
• Bearing raceway profiles control maximum stress levels to provide greater product durability
• Optimized cage designs, including steel and polymer configurations, improve capacity and roller retention
• Features the highest bearing life ratings in the industry as certified by Germanischer Lloyd

• Preset, pre-greased, assembled and sealed at the factory – eliminating the risk of improper bearing setting and contamination and reduces the potential for bearing damage.
• Unitized assembly contains the bearing cones, bearing cup, triple-lip seals and grease – simplifying installation.
• “Sealed-for-life” design eliminates frequent inspections and re-lubrication – improving employee safety, uptime and productivity.
• Dimensionally interchangeable with current industry-standard bearing assemblies and seals, requiring no modification of the sheave bore.
• Designed to operate within existing industry-standard snap ring and groove dimensions.

• Pre-set, pre-greased and pre-sealed.
• Features an active sensor capable of sensing down to zero speed. Sensor’s speed information is used for vehicle dynamics control systems, speed control, speedometer, odometer, trip computer and other purposes.
• Sensor-Pac utilizes extremely small sensor-to-target wheel gaps, enabling a much smaller and more cost-effective sensor.
• Sensor mounted internally for protection against debris, corrosion, thermal shock, and other hazards that threaten externally-mounted sensors – helping reduce warranty costs.
• Sensor will operate without compromise, despite temperature extremes or prolonged braking conditions.
• Designed for superior performance in a minimal space. Timken engineers have packaged the sensor within the bearing without increasing overall dimensions to promote high performance and equal load carrying capacity in a small space.

Timken^® RacePac^® Tapered Roller Bearings*

• 30% cooler operating temperatures**: Improved internal geometry reduces sliding contact stress and provides consistent rolling torque.
• Reduce bearing replacement costs: Enhanced durability due to lower operating temperatures.
• Improved drivetrain efficiency: Reduced bearing power loss results in a cooler running hub.
• Ready to install: Bearings pre-lubed, pre-set and pre-assembled to Timken specifications.

Timken-Designed Zero-Torque Seal*

• Excellent performance: Seal works off positive air pressure, keeping contaminants out.
• More horsepower potential due to less seal drag.

Hubs

• More speed: 2 pounds lighter (8 pounds total unsprung weight reduction).  Meets minimum weight requirement of 6.25 lbs.
• Durability maintained with lightweight design.

Grease Containment Dams

• Maintain proper lubrication: Keeps grease in critical areas; additional grease dam in the rear hub helps reduce operating temperatures.

Engineered Spacers

• Reduces setup time and increases stiffness: Precise design helps optimize bearing setting.

*Available exclusively in RacePac. ** Rear bearing rig testing.

Rear RacePac Enhanced and Tested for Stronger Performance

• Benchmarked against the existing RacePac, we enhanced the robustness and conducted successful 12-hour internal rig tests.
• History shows that successful testing is an indicator of stronger performance regardless of car setup or track.
• Multiple tests completed designed to optimize grease fill, lubricant retention, bearing setting and enhanced bearing internal geometry.
• More durable and lighter hub with less unsprung weight on the rear axle.
• Reduces the amount of cooling needed for rear hubs which can enable additional aerodynamic adjustments.

• 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 commonization between driven and non-driven designs.
• Fully serviceable wheel speed sensor is internally mounted and protected from road hazards, debris and potential damage.
