SKF PSM series bushings are sintered bronze, self-lubricating components built to handle radial loads in rotating or oscillating motion. They suit a broad range of industrial equipment where space is tight and maintenance is minimal. The porous bronze structure holds oil, which lowers friction and wear. MR Industrial Accessories supplies this line within its selection of power transmission and support parts.
The part number on a PSM bushing encodes its dimensions. Take PSM 202620 A51: the first two digits give a 20 mm bore, the next two a 26 mm outer diameter, and the following two a 20 mm length. The A51 suffix points to a particular material or tolerance version. The same pattern applies to PSM 303825 A51 and PSM 405040 A51. This makes it straightforward to find a bushing by size.
These bushings fit situations where lubrication is difficult or maintenance happens at long intervals. They appear in farm equipment, earthmoving machines, conveyors, pumps, fans, and clutch systems. Their capacity for moderate loads at low to medium speeds makes them a practical choice when replacing standard bushings during repairs.
Choosing the right bushing starts with checking shaft and housing dimensions, along with the load and speed involved. During installation, keep everything aligned to prevent uneven wear. Clean the mating surfaces, and if needed use a mandrel to press the bushing in without damage. A light oil that works with sintered bronze at the start helps extend service life. In dirty environments, consider adding seals.
SKF PSM bushings can be swapped with equivalent products from other makers if the dimensions and material match. Compare tolerances and load ratings before substituting. While PSM is an SKF designation, other suppliers offer sintered bushings in standard sizes. For a safe interchange, check the operating conditions with a specialist.

Frequently asked questions
- What does the PSM code indicate on SKF bushings?
- PSM identifies SKF's friction bushing series. The numbers that follow give the inner diameter, outer diameter, and length in millimeters. The alphanumeric suffix denotes material or tolerance variants.
- Do these bushings need extra lubrication?
- They are self-lubricating because of their oil-impregnated porous structure. In demanding applications, adding lubrication can prolong service life. Check the operating conditions to decide.
- Can I use a different brand instead of an SKF PSM bushing?
- Yes, if the dimensions and material are equivalent. Verify tolerances and load capacity. For a reliable replacement, consult a specialist or send us the dimensions via WhatsApp.
