Abstract: A plain bearing which may have superior operational characteristics, such as the ability to work in high temperature environments with aluminum housings, or which may have the ability to support an axial load, or which may have an outer ring formed entirely of polymer or lubricant impregnated polymer, and/or components thereof.

Abstract: A wheel bearing useful for automobiles includes an axle shaft and an axle tube around the shaft, inner and outer bearing races defined respectively at the outer periphery of the shaft and the inner periphery of the tube. A circumferential row of balls and a circumferential set of rollers disposed axially apart between the inner and outer bearing races to form a ball bearing and a roller bearing, in parallel, for supporting the axle shaft within the axle tube.

Abstract: A roller for a trolley assembly, which includes at least one track and at least one pin adapted to carry a hanger, includes, in one embodiment thereof, a bearing substantially split to define at least two independent parts of the split bearing. A housing rollingly engages along the at least one track and houses the bearing. A bushing is housed within the housing, carries the pin, supports the bearing about the bushing, and defines at least one shoulder adapted to substantially positively abuttingly engage the at least two parts of the bearing to substantially prevent rotation of the bearing about the bushing during rolling of the housing along the at least one track.

Abstract: The unitary center support bearing subassembly comprises a bearing over which a plastic bearing housing has been molded while simultaneously molding the plastic bracket insert and joining members which space and fix the distance between the bearing housing and the bracket insert. The joining members are removed or broken prior to molding the overmolded rubber portion, or, if the joining member is flexible, the overmolded rubber portion is molded while maintaining the joining member.
