SKF friction bushings of the PCM E/VB series are thin-walled self-lubricating bushings that combine a metal backing with a sliding layer of PTFE and bronze. They are used to support oscillating or rotating movements under conditions of high load and low speed, where constant lubrication cannot be maintained. Their compact design allows them to be mounted in tight spaces and to replace bronze bushings or bearings in applications where reduced maintenance is sought.

The designation PCM … E/VB… reads as follows: PCM identifies the SKF friction bushing family; the digits that follow indicate key dimensions, such as bore diameter, outer diameter and width, coded in groups of two figures. The suffix E indicates the standard version, while VB corresponds to a design variant, generally linked to the type of sealing or the composition of the sliding layer. For example, PCM 040506 E/VB055 and PCM 040510 E/VB055 share the same bore and outer diameter, but differ in width, which allows you to choose according to the available space and the load to be supported.

These bushings are used in industries such as automotive, metalworking, food and road machinery. They appear in hydraulic cylinder joints, camshafts, gate hinges, packaging equipment and steering mechanisms. In Argentina, they are commonly found in the repair of agricultural machinery, where dust and lack of lubrication shorten the life of conventional bushings. Their ability to work without greasing makes them suitable for hard-to-reach points.

To select the correct bushing, take into account the radial load, the sliding speed and the operating temperature. Assembly must be carried out carefully: the bushing is press-fitted into the housing, and then the bore diameter is calibrated if necessary. Alignment between the shaft and the housing is critical to avoid premature wear. Although they are self-lubricating, a film of oil or grease can extend their life in severe applications. Verify that the shaft surface is ground and has adequate hardness.

Regarding equivalences, SKF bushings of the PCM series can be interchanged with products from other manufacturers that follow the same dimensional designation, such as PAP or PCM bushings from different brands. However, not all suffixes match in composition or tolerances. Therefore, it is always advisable to compare the original product's data sheet with that of the replacement. At MR Accesorios Industriales we sell SKF as an official brand, and we can advise you to find the appropriate equivalent reference.
