Abstract: A separator or cage for a row of ball bearings designed to reduce friction on the balls. The pocket surfaces in the separator have recesses in the region of the axial "poles" of the balls which prevents contact between the balls and the separator pocket walls. Over the rest of the separator, the pocket walls are near enough to the balls to define a hydrodynamic lubricating film. Also over the rest of the separator pockets, the interior surfaces of the pockets are shaped to face the respective balls and to define a wedge-shaped slot with the ball for development of a hydrodynamic lubricating film as the balls rotate in either direction around their axes. The separator is comprised of two strips fastened together. Each strip has a complementary C-shaped pocket half depression, and the two strips joined together define the complete pockets that enclose the balls between the axial poles of the balls.

Magnetic liquid elements are supported radially inward of the sealing ring by a magnet in the sealing ring. The pre-seal has an annular groove opening toward the bearing inner ring for holding escaping liquid. An axially outwardly facing shoulder formed on the bearing inner ring raceway cooperates with an axially inwardly facing inside of the pre-seal for defining a slot between them and those surfaces are inclined obliquely to the rolling elements and to the axis of the bearing.

Abstract: A wheel mount for a motor vehicle including a hub which is welded to another part, such as a swivel joint or a holding part. The hub carries on it the inner ring of the anti-friction bearing for the hub. Projecting axially from the hub and from the other part are correspondingly radially spaced projections which, prior to welding and deformation of the projections, are of lengths great enough to hold the hub and the other part axially apart. Upon welding temperature being achieved at the projections, e.g. by friction, the hub and the other part are pressed together which deforms the projections, forming beads of deformation, and the hub and other part are welded at the beads of deformation. The hub and other part are pressed together until the axial ends of the hub and other part contact.
