Abstract

A linear motion rolling bearing including an outer sleeve, a cage within the sleeve for guiding rolling elements, a plurality of endless channels including axial races and return passages filled with rolling elements, and end rings covering the outer peripheral surfaces of the cage which extend axially beyond the outer sleeve, has provision for lubricating these channels while the bearing is in operation by radial excavations defined between adjacent surfaces of the outer sleeve and each end ring, the excavations communicating with an annular groove in the bore of the housing and portions of an annular groove in the outer periphery of the cage extending circumferentially between races of adjacent endless channels.
