SKF PRM series friction bushings are cylindrical plain bearings built to handle radial loads in rotating or oscillating applications. They serve as an alternative to rolling bearings where low maintenance, corrosion resistance or quiet running is important. MR Industrial Accessories LLC supplies this line to maintenance and purchasing teams in the United States and several Latin American countries, with technical support to match the right size to your equipment.

The part number itself tells you the size. After the letters PRM, six digits give the main dimensions in millimeters: the first two are the inner diameter, the next two the outer diameter, and the last two the width. So PRM 323630 means a bushing with a 32 mm bore, 36 mm outer diameter and 30 mm width. PRM 505560 has a 50 mm bore, 55 mm outer diameter and 60 mm width. This coding lets you identify a bushing quickly without looking up extra tables.

These bushings appear in food, chemical, textile and agricultural machinery, as well as in conveyors, pumps, mixers and fans. They suit equipment where lubrication is limited or where noise needs to be kept down. Slow oscillating movements, such as in joints and pins, are another common use, since the bushings support moderate radial loads.

When selecting a PRM bushing, start with the shaft diameter, the expected radial load and the operating environment. Check housing and shaft tolerances carefully to achieve the right fit, usually with slight interference on the outside. Depending on the version, lubrication may be permanent through self-lubricating material or require periodic greasing. Keeping the shaft and housing aligned helps prevent premature wear.

SKF PRM bushings can be interchanged with products from other manufacturers that use the same dimensional designation, including bushings from similar series. Material and tolerances can differ between suppliers, so it is worth confirming those details before substituting a component. Our team can review your application and suggest equivalents when needed.
