12pcs Sleeve Bearings 15mm Bore 20mm OD 15mm Length Sintered Iron Self-Lubricating Bushings Description: Sleeve bearings are also known as plain bearings or bushings, mostly for guiding or reducing friction in linear applications. 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 iron bushings are most suitable for applications with rotating movements and where self-lubricating properties of the material. Suitable for a vast variety of industrial equipment such as electrical equipment, household equipment, printing machinery, and machine tools.
