ABSTRACT:
A pair of relatively rotatable support members, separated by a gap centered on the axis of rotation, engage each other through a multiplicity of elastically deformable sliding heads of low-friction plastic material projecting from one support member into the gap and resting against a confronting contact surface of the other support member. Each sliding head is tightly embraced by a rigid retaining sleeve which is positively guided on the first support member for movement perpendicular to the contact surface and is urged by one or more biasing springs toward that surface so as to surround the entire projecting portion of the sliding head under all loading conditions.
