The SKF PER.Z RSTLD is a Y-bearing insert built with an extended inner ring and secured to the shaft by set screws, so it can be fitted into split or pillow block housings. It suits rotating shaft positions where some misalignment has to be absorbed and where grease needs to stay in place. The RSTLD seal arrangement combines two contact lips with an outer metal flinger, which helps keep dust and moisture away from the bearing. MR Industrial Accessories supplies this brand for maintenance and repair work.

Reading the code PER.Z9504-2RSTLD helps when comparing replacements. PER marks the insert family with an extended inner ring. Z tells you the inner ring is locked with set screws. 9504 is the size code that fixes diameter and width. The 2RSTLD ending covers sealing: two contact lips plus a metal flinger on the outside that shields the lip from coarse dirt and splashing water.

These inserts show up on belt conveyors, bucket elevators, mixers, mills and other process equipment, as well as on agricultural machines such as seeders and combine harvesters where dust and weather are constant. Because the insert can self-align, it works on long shafts that deflect or on mountings that are not perfectly lined up. Food, cement, mining and aggregate plants are common places to find them.

Selection starts with the shaft diameter and the housing type you already have. RSTLD sealing fits dirty or damp locations; in a clean, high-speed position a simpler seal may be enough. Before mounting, clean the shaft and put on a thin film of lubricant. Tighten the set screws with the correct wrench and check that the inner ring sits centered. Many of these inserts are lubricated for life, though harsh conditions can call for relubrication.

Y-bearing inserts can be swapped between brands when dimensions and locking method line up. SKF, NSK, NTN, FAG and Timken all offer comparable lines, but the sealing and locking suffixes differ from one maker to another. Shaft diameter by itself does not settle it: total width, screw position and seal type all have to be checked. We can help you match a replacement without touching the housing.
