The SKF PER.RPP series is a line of insert bearings that lock onto the shaft with set screws and feature an extended inner ring. They are designed to sit inside split plummer block, pillow block or take-up housings, which makes them a practical choice for conveyors, fans, mixers and agricultural equipment. MR Industrial Accessories supplies this series.

Reading a PER.RPP code is straightforward once you know the pattern. PER marks the family: Y-bearings with an extended inner ring and set screw locking. The digits that follow (205, 309, 5203, and so on) define the size and dimension series. After RPP comes a final number that points to a variant in sealing, internal clearance or outer ring design. So PER.205RPP9 and PER.205RPP10 share the same basic dimensions but differ in that final digit. The same logic applies to PER.309RPP55 or PER.5203RPP2: the trailing number is a construction detail that must be checked against the table. Always confirm shaft diameter, housing type and operating conditions before settling on a code.

These bearings show up in a broad range of industrial settings: belt conveyors, bucket elevators, mills, mixers, dryers, fans, and equipment in the food, cement, mining and agricultural sectors. They also appear in grain processing machinery, aggregate plants and irrigation systems. Because they are self-aligning, they absorb small misalignments between shaft and housing, which is common in vibrating or variable-load equipment. Mounting in split plummer block, take-up or pillow block housings keeps field replacement simple.

Selection comes down to shaft diameter, load type (radial, axial or combined) and the environment. Sealing is critical: RPP suffixes typically denote double-lip or contact seals that keep out dust and moisture. In dirty or washdown-heavy areas, a more robust seal is worth considering. Lubrication may be lithium or synthetic grease, depending on temperature and speed. During mounting, clean the shaft and remove burrs, then tighten the set screws with the correct wrench so the inner ring cannot spin. Check housing alignment and leave the axial clearance recommended by the manufacturer.

Interchangeability is possible with other brands that follow the same dimension standard, but suffixes are not always equivalent. An RPP9 from one maker may not match the sealing or clearance of another. When substituting, compare diameter and width, but also locking method, sealing and permissible load.
