Performance-engineered for race-car cornering and stability

Race car and high-performance vehicle owners demand exceptional wheel end performance, cornering and stability. The SKF X-Tracker delivers all of it and more. The X-Tracker is currently used in a number of high-volume, high-performance luxury vehicles.

The X-Tracker features a double row angular contact ball bearing arrangement in which the outboard row has a larger diameter and contains more balls than the inboard row. This unique, asymmetrical design increases the bearing load carrying capacity and operational life, while significantly improving camber stiffness compared to traditional symmetrical hub units.

Improving camber stiffness allows the brake rotor to tilt less during vehicle cornering, which in turn reduces brake caliper piston knock back, allowing the driver to brake later, and reducing lap times on the track. The small inner ring is retained with orbital forming, which means the bearing will stay in preload under heavier loading, providing a longer service life.

Low friction X-Tracker

To fulfill the demand for energy efficiency solutions, SKF also offers the low friction X-Tracker which reduces CO2 emissions significantly compared to  the standard X-Tracker.

This solution was developed specifically for upper and premium range of vehicles that have a strong demand of reduced CO2 emissions, but it can be tailored to fit any vehicle application.
These wheel bearing units are suitable for both newly developed vehicles as well as modifications to existing designs, expandable to any bearing geometry, and available for normal and heavy duty applications.
