Rolling body retaining cage for antifriction bearing, has reserve with lubrication channels in which matrix is disposed, and association channel provided between housing and emerging in surfaces, where matrix is disposed in two reserves

摘要

The cage has an annular body (1) with a lubricant reserve having lubrication channels (6) in which a porous solid matrix with lubricant is disposed. The reserve has an association channel (12) associated with another retaining cage. The channel (12) is provided between hemispherical housing (2) and emerges in rear and front surfaces of the body, where the housing is provided in the front surface. The matrix is disposed in the reserve and another lubricant reserve of the latter cage by filling the channels and an annular shaped rear space formed on the rear surface.
