A slipper bushing is described as being comprised of a number of succeedingly larger cylindrical sleeves, beginning with a rigid, inner sleeve, followed by a polymeric sleeve, then a resilient elastomeric sleeve, and finally, a rigid, outer sleeve. The inner cylindrical surface of the elastomeric sleeve abutting the outer cylindrical surface of the polymeric sleeve, is provided with a number of circumferentially oriented grooves. A lubricant is placed between the interfaces of the polymeric and elastomeric sleeves and moves into and out of the grooves, as the bushing operates. End caps are used at the flange and barrel ends of the slipper bushing to cover the sleeves and seal the interfaces between them from contaminants.
