Oiled Bearing Sleeves have a small friction coefficient of about 0.12-0.18.They are made of powder-metallurgical metal, which has a large working temperature range from -80 degrees Celsius to 120 degrees Celsius.Bushings provide strong housing for a shaft or fastener. They also help to reduce bores' diameter or to replace worn-out original bushings on wheels.Sintered bronze bushings are most suitable for applications with rotating movements and where self-lubricating properties of the material.
