Wheel bearing spacers for racing automobiles

A wheel bearing assembly for a wheel assembly of a motor vehicle, wherein said wheel bearing assembly includes a wheel hub having inner and outer bearing race shoulders for receiving respective inner and outer roller bearing races and roller bearing housings with roller bearings therein, said wheel bearing assembly adapted for being mounted on a wheel axle, said wheel bearing assembly comprising:

• (a) an annular spacer body including a cylindrical body portion and a frustoconical body portion, and having a central opening for permitting the spacer body to be positioned onto the axle between the inner and outer roller bearing housings for exerting an axial compression thereon;
• (b) a spacer cap having a central opening for permitting the spacer cap to be positioned onto the axle between the inner and outer roller bearing housings and in engaging coaxial alignment with the spacer body for engaging the other of the inner or outer roller bearing housings;
• and
• (c) at least one annular shim having a central opening for permitting the shim to be positioned onto the axle between the spacer body and the spacer cap, the shim having an axially-extending dimension predetermined to produce with the spacer body and the spacer cap a combined axially-extending dimension suitable to create and maintain a predetermined amount of axial compression on the inner and outer roller bearing housings against the respective inner and outer bearing races while preventing rotation of the inner and outer roller bearing housings relative to the axle.
