SKF plain bearings of the PRMF series are thin-walled cylindrical bushings that are press-fitted to reduce wear between moving surfaces. They are used in shafts, pins and joints where there is no room for a complete bearing. Their design allows them to be replaced when the clearance exceeds the tolerance, extending the service life of the assembly without machining the housing.

The PRMF designation is read as a dimension code: the first digits indicate the inner diameter and the following ones the outer diameter, both in millimeters. For example, PRMF 252825 corresponds to a plain bearing with a 25 mm inner diameter, 28 mm outer diameter and 25 mm length, but the dimensions vary according to the code. The numeric suffixes may vary to indicate the total width or the type of material, but in this series the pattern remains constant. Always verify the full code before requesting equivalents.

These plain bearings are used in agricultural machinery, soil movement equipment, conveyors, presses and hydraulic systems. In Argentina they are common in the repair of seeders, combine harvesters and trailers, where dust and load conditions demand wear-resistant bushings. They also appear in pumps, fans and machine tools that operate with oscillating movements or slow rotation.

To select the correct plain bearing, take into account the shaft diameter, the housing diameter and the seat width. Assembly is done by pressure or with anaerobic adhesive, ensuring perpendicular alignment. Lubrication is key: if the plain bearing has no grooves, an external lubrication system must be provided. Excessive clearance or a scratched shaft surface accelerates wear; it is advisable to verify the roughness and hardness of the shaft before installing.

As for equivalents, SKF PRMF plain bearings can be interchanged with bushings from other brands that share the same standardized dimensions. There is no universal code, but catalogs usually list equivalent metric measurements. If you need to replace an original bushing, always compare the inner diameter, outer diameter and length, and check the recommended tolerance for the housing.

MR Accesorios Industriales sells the SKF line. If you have the plain bearing code or the shaft and housing measurements, send us the data via WhatsApp and we will quote the right option. We can also advise you on assembly and lubrication so that the replacement lasts as expected.
