X-TRACKER BY SKF

A unique line of high performance hub units from SKF. 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 SUVs. SKF premium hubs are 100% tested to actual OE specs.

X-Tracker

Designed specifically for cars, light duty trucks and SUVs :

• Double row angular contact ball bearing arrangement 
• Outboard row at a higher diameter; contains more balls than the inner row 
• Increases bearing’s capacity while improving hub stiffness by 50% over a traditional bearing unit 

Benefits 

• Allows wheel to run truer during cornering and acceleration 
• Reduces deflection of hub face and wheel; provides better steering, handling and vehicle dynamic behavior 
• Reduces brake wear due to true running of rotors; helps reduce brake warranty costs 
• Improves both NVH (noise/vibration/ harshness) characteristics and bearing performance Longer service life 
• Alternative to tapered bearing unit

X-Tracker Hybrid

A hybrid bearing designed by SKF to combine the strengths of the ball and tapered roller hub units. The next generation of X-Tracker hub bearings from SKF, designed for light trucks and SUVs.

Designed specifically for light duty trucks and SUVs:

• Distinctive ball and taper bearing arrangement 
• Outboard row at a higher diameter; contains more balls than traditional design 

Benefits 

• Asymmetrical design provides increased hub stiffness 
• Enables truck to handle more like a car 
• Reduced deflection of the hub face provides better braking and handling 
• Improved steering accuracy and vehicle dynamic behavior 
• Improved brake wear and less NVH (noise/vibration/harshness) due to truer running of the rotor
