ABSTRACT:
A bearing arrangement for a wheel of a vehicle is provided, comprising a cylindrical hub integrally formed with a flange connected to the wheel, extending axially outward enclosed in a second flange. The second flange further encloses a bearing seat proximate the hub, and a double row anti-friction bearing including roller elements travelling in a single outer race and twin inner races. The union between the second flange and the cylindrical hub forms a shoulder containing at least two grooves. The grooves are configured to receive a removal tool, used to pry the inner races away from the hub. The diameter of the shoulder can either be equal to or larger than the diameter of the inner race. The strength of the hub can thus be enhanced without increasing the pressure on the races, maintaining easy removal capability.
