摘要： A unitary one-piece rolling element retainer for roller bearings consisting of inner and outer rings and rolling elements between the rings. The retainer comprises a body member made of a foamed plastic material consisting of at least one homogeneous liquid impermeable hard and rigid outer peripheral surface portion and at least one porous portion of the same material. The porous portion is filled with the lubricant and includes at least one pocket for a rolling element in the body member. The rolling element contacts the porous portion to draw lubricant during operation and also contacts the outer surface portion at the periphery of the pocket to prevent escape of lubricant from the container except through contact with the rolling element.
