SKF PCM M series plain bearings are thin-walled self-lubricating bushings that combine a steel backing with a sintered bronze layer and a PTFE and lead mixture. They are used to support radial loads in oscillating, rotating or sliding movements, where continuous lubricant supply is not possible or not advisable. Their compact design allows them to be mounted in confined spaces and to replace solid bushings with lower load capacity.

The designation PCM identifies SKF plain bearings with a metal backing and sliding layer. The numbers that follow indicate the basic dimensions: in PCM 081012 M, for example, the first two digits correspond to the inside diameter, the next two to the outside diameter and the last two to the width, all in millimeters. The suffix M indicates the standard version with PTFE and lead layer. Other examples such as PCM 101215 M or PCM 121420 M follow the same logic: each pair of digits defines a dimension. Always verify the complete code to ensure the correct size.

These plain bearings are used in a wide variety of industrial equipment in Argentina: presses, machine tools, hydraulic and pneumatic cylinders, cranes, elevators, material handling equipment and agricultural machinery. They also appear in automotive and heavy transport applications where wear resistance and low friction without frequent maintenance are required. Their ability to work under radial load conditions and reciprocating movements makes them suitable for joints, pins and shafts that rotate at moderate speeds.

To select the correct plain bearing, take into account the radial load, sliding speed and operating temperature. The PCM M series withstands relatively high loads compared with plastic bushings, but it is not intended for high speeds or continuous rotation at high speed. Mounting must be carried out with the shaft and housing clean and free of burrs; a slight interference fit in the housing and adequate diametral clearance on the shaft are recommended. Initial lubrication is not necessary, although in highly contaminated environments the assembly can be sealed to extend service life.

Regarding equivalents, plain bearings with steel backing and PTFE layer are known under different names depending on the manufacturer. There is no universal nomenclature, so interchangeability requires comparing dimensions, tolerances and load capacity. SKF is an official brand that MR carries, and its products maintain recognized quality standards. If you need to replace an existing bushing, the safest approach is to start from the actual housing and shaft measurements and compare them with the manufacturer's table.
