Home / Bearings / Plain Bearings

Plain bearings are tribological components that carry a load while in contact with and moving relative to another part. Also referred to as bushes, bushings, or sleeve bearings, they are usually cylindrical in shape and contain no moving parts. Construction may be solid or with a split joint (wrapped bearings) for easier installation. They are manufactured with different constructions, and product selection depends on the operating conditions of the application and performance requirements.

Principal Characteristics:

  • Metal-polymer plain bearings
  • Engineered plastics
  • Fiber-reinforced composite bearings
  • Monometallic, bimetallic, and sintered bronze plain bearings

Plain bearings are used for sliding, rotating, oscillating, or reciprocating motion. In sliding applications, they serve as slide bearings, bearing strips, and wear plates. In these applications, the sliding surfaces are usually flat but can also be cylindrical, and movement is always linear rather than rotating. Rotating applications involve cylindrical surfaces and one or two directions of travel. Oscillating and reciprocating applications involve flat or cylindrical surfaces, but bi-directional travel.
