ABSTRACT:
A radial seal useful in linear ball bearings and designed to be secured during transportation as well as during operation of the bearing includes an arcuate disk portion having opposite sides. An arcuate projection is provided on each side of the disk portion, at least one of which is axially oriented. The projections are designed to have different diameters. This produces a stepped seating surface along the outside diameter of the radial seal that effects a reliable seating of the radial seal in the linear ball bearing. The radial seal can also be designed with two axially oriented projections disposed at different diameters on one side of the disk portion for projecting into an annular groove on the frontal face of the outer ring of the linear ball bearing. By constructing the projections with circumferential outer faces that slightly diverge in a cone-shaped manner, the projections further inhibit the seal from falling out of the groove.
