SKF has gained the contract for the wheel hub bearing units for the front and rear wheels of the new 2006 Cadillac STS-V. SKF is supplying its X-Tracker™ unit, which is a new bearing design improving the performance, cornering and stability characteristics demanded by today’s luxury vehicles.

The X-Tracker is an asymmetrical hub bearing unit consisting of a double row angular contact ball bearing arrangement, in which the outboard row has a larger diameter than the inboard row and contains more balls. This unique design increases the bearing load-carrying capacity and operational life.
