SKF PBM M1G1 series friction bushings are thin-walled cylindrical components made from a PTFE and bronze composite. They handle radial loads in rotary and oscillating motion, reducing friction and wear between metal surfaces without additional lubrication. MR Industrial Accessories supplies this line as part of its power transmission and maintenance catalog for customers in the United States and Latin America.

The part number tells you the size and material. PBM identifies the SKF friction bushing category. The following digits give the main dimensions in millimeters, such as bore, outside diameter, and length. The M1G1 suffix denotes the construction: a PTFE layer on a sintered bronze base. For instance, PBM 202820 M1G1 and PBM 506050 M1G1 are two different geometries in the same series. Always confirm the actual shaft and housing dimensions before selecting.

These bushings appear in food, chemical, petrochemical, automotive, and machine tool plants. Common equipment includes packaging lines, conveyors, pumps, valves, presses, and lifting systems. Because they run without lubrication, they suit locations with limited maintenance access or strict cleanliness requirements. You also find them in agricultural seeders and harvesters, and in plastics injection molding and extrusion machines.

Selection depends on radial load, sliding speed, operating temperature, and motion type (rotary, oscillating, or linear). Check housing and shaft tolerances; an interference fit in the housing and a sliding fit on the shaft are typical. Mount carefully to avoid damaging the PTFE layer. Shaft and housing alignment is critical to prevent side loads. In highly contaminated areas, add seals. Lubrication is not required, but a compatible grease layer can help during assembly in dirty environments.

For interchangeability, SKF PBM M1G1 bushings can replace other friction bushings from brands such as GGB, Igus, or Federal Mogul when dimensions and material match. Compare allowable load and maximum operating temperature to confirm equivalent performance. Not all bushings swap directly; verify bore, outside diameter, length, and material type. Our team can help you evaluate the best option.
