Description

Sleeve bearings consist of a metal, plastic or fiber-reinforced composite sleeves that reduce vibrations and noise by absorbing friction between two moving parts using a sliding motion. Sleeve bearings, which are often used on fractional horsepower motors, are made from babbitt, brass, or bronze. Graphite may be impregnated into the metal to enhance the lubrication. Because the metal in these bearings is much softer than the steel shaft of the motor, the bearing will wear rather than the motor shaft
