A seal for a roll neck bearing has a two interlocked components - a rotating component fitted to the inner race of the bearing and a stationary component fitted to the outer race. The rotating component includes a shield which fits around the end of the inner race, and, while it establishes a static barrier along the inner race, it can float or be displaced axially on the inner race. The stationary component has a seal case which fits snugly in a bore that opens out of the end of the outer race, it being trapped in that bore by a chock into which the bearing fits. Both the shield and case have axial walls and radial walls, and at the ends of their radial walls carry elastomeric seal elements. The seal element of the shield contacts the axial wall of the seal case, whereas the seal element of the seal case contacts the axial wall of the shield and further establishes a labyrinth along the shield. The two seal elements include bumpers which are presented toward the radial walls and limit the distance the rotating component may be displaced axially relative to the stationary component.

Two component bearing seal with bumpers

A wheel mounting assembly which unifies the suspension strut and trailing control arm in a single unitary member which provides a principal part of a wheel bearing assembly. The unitary member avoids a multiplicity of parts which is a known problem common in the automotive art, and it reduces costs and weight, and results in a simpler job of repair when necessary. The companion member of the mounting system is associated with the wheel to provide a unitary member with the wheel supporting flange and a hollow sleeve to receive a shaft or spline.
