ABSTRACT:
The normally smooth and uninterrupted cylindrical wheel and brake drum pilot surface of a wheel bearing spindle is process in a novel manner designed to reduce the potential for water induced corrosion at the contact interface. A low lead angle, square bottomed spiral cut reduces the pilot surface area considerably and provides water drainage channels radially inset from the remainder of the surface area. There is considerably less area in the contact interface to corrode, and the remaining area has water well drained away from it.
