A unique line of high performance hub units from SKF
X-Tracker hub bearings
Developed in response to OE requests for a high performing hub bearing unit that provides precision handling and braking characteristics, SKF engineers developed the X-Tracker hub bearing. The X-Tracker is a performance hub unit that will deliver improved handling and comfort characteristics to cars, light duty trucks and SUV’s. SKF’s X-Tracker consists of a double row angular contact ball bearing arrangement, in which the outboard row is at a higher diameter and contains more balls than the inner row. This unique design increases the bearing’s capacity while improving hub stiffness by 50% over a traditional tapered bearing unit.
A stiffer hub provides many benefits including
- Wheels runs truer during cornering and acceleration
- Reduces deflection of the hub face and wheel for better steering, handling and vehicle dynamic behavior
- Reduces brake wear due to true running of rotors, which helps reduce brake warranty costs
- Improves both NVH (noise/vibration/harness) characteristics and bearing performance
- Provides designers and systems integrators an alternative to a tapered bearing unit, freeing them to improve overall vehicle performance

Designed for light duty trucks and SUV's
Features and performance
The SKF X-Tracker Hybrid hub bearing is designed to combine the strengths of ball and tapered roller hub units.
- Asymmetrical design provides increased stiffness
- Enables truck to handle more like a car
- Reduced deflection of hub face provides better braking and handling
- Improved steering accuracy and vehicle dynamic behavior
- Improved brake wear and resulting NVH (noise/vibration/harness) due to truer running of the rotor
