The PER.W RPPB line from SKF covers Y-bearing inserts built with an extended inner ring and locked in place by set screws. They mount inside split plummer block housings or tensioner units, which suits equipment where perfect alignment is not realistic and small deviations have to be taken up. A double-lip seal keeps grease in and keeps dust out, so the insert holds up in areas with a moderate amount of dirt.

Reading the code helps you order the right part. The letters PER.W describe an insert with an extended inner ring and screw locking, while RPPB points to the double-lip seal with extra protection. The digits in the middle, as seen in PER.W208RPPB10, PER.W209RPPB2 or PER.W211RPPB2, are tied to the shaft diameter through the series table. That figure is not a millimeter measurement on its own, so it has to be checked against the catalog. For a reliable replacement, send us the full reference printed on the bearing you are taking out.

These inserts show up in transmission and conveying equipment that works hard. Typical locations include belt conveyors, bucket elevators, mixers, mills, centrifugal pumps and industrial fans, plus road machinery and material handling systems. The extended inner ring makes mounting easier on shafts with looser tolerances and allows screw locking, so a field replacement can be done without a press.

Choosing the right Y-bearing comes down to shaft diameter, the nature of the load (radial, axial or combined) and the surrounding conditions. An RPPB seal fits where dust, moisture or splashes are present; in a very clean area a simpler seal may be enough. At mounting, confirm the shaft is clean and free of burrs, then tighten the set screws with the correct wrench so the inner ring cannot spin on the shaft. Grease from the factory normally lasts the full service life, though severe duty may call for periodic relubrication. Keep the housing aligned to avoid putting extra stress on the seal.

When swapping out a Y-bearing, interchangeability across brands comes down to the main dimensions and the locking method. SKF, FAG, NSK, NTN and Timken all offer inserts with standardized dimensions, but the seal, permissible load or locking system can differ. The same shaft diameter may exist in several outer ring or seal variants, so not every part number is a direct match. Comparing the critical dimensions and the locking type is the safe route. If anything is unclear, send the original part number and we will help you locate the correct equivalent.

MR Industrial Accessories supplies SKF Y-bearings as a brand. To request a quote, message us on WhatsApp with the complete part number from the bearing or the housing. That lets us pin down the exact variant and point you to the right option for your equipment. We also handle technical questions and support the selection of power transmission components.
