SKF X-Tracker hub unit

SKF has introduced the X-Tracker Series of hub units in response to the growing use of light trucks as family sport vehicles. The X-Tracker hub unit 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 design increases the bearings capacity while improving hub stiffness by 50 per cent over a traditional tapered bearing unit. While the X-Tracker hub units brings car-like handling and comfort characteristics to high performance light duty and SUV applications, it also allows the wheel to run truer during cornering and acceleration; reduces deflection of the hub face and wheel, which provides better steering, handling and vehicle dynamic behavior; reduces brake wear due to the true running of rotors; and improves both NVH (noise/vibration/harness) characteristics and bearing performance.
