The SKF PER.GW is a Y-bearing insert that carries a spherical outer ring and a rubber seal, made to sit inside split plummer block housings and bearing units. It fits equipment where perfect alignment is not realistic and where dust, moisture or washdown spray are part of daily operation. Mounting is straightforward, and the design keeps the bearing running dependably in tough surroundings. MR Industrial Accessories supplies this line to maintenance and purchasing teams.
Reading the code is the first step in ordering the right replacement. PER.GW tells you the bearing has a spherical outer ring and a rubber seal. The RRRB block describes the seal configuration, while the A and B letters mark design variants. Take PER.GW5209RRRB52-A: the 5209 bore pairs with the RRRB seal and the 52-A variant. Miss a suffix and you may end up with a part that will not seat correctly in the housing.
You will find these bearings on conveyors, belts, elevators, mills, mixers and other process equipment. Food plants, feed operations, aggregate sites and agricultural facilities rely on them, and they also show up on road machinery and material handling gear where ruggedness and infrequent attention matter. The rubber seal suits areas with dirt, dust or regular washdown.
Selection starts with the shaft diameter and the housing type. The RRRB seal keeps contaminants out and grease in, so in very dirty settings it pays to inspect the lip condition. Keep internal clearance and lubrication as they came from the factory, and avoid mixing bearings from different series on the same machine. When mounting, line up the housing and never strike the outer ring. Good alignment is what gets you the longest service life.
Y-bearings can be swapped between brands when dimensions, seal type and outer ring configuration line up. Matching diameter alone is not enough: compare width, radius and the shaft locking method as well. If anything is unclear, send the full part number and your housing dimensions. Our team can point you to the right equivalent.

Frequently asked questions
- What does the RRRB suffix mean on this bearing?
- RRRB identifies the rubber seal type that shields the bearing from dust and moisture. It is a standard configuration for industrial settings where contaminants are present. If your equipment carries a different suffix, send us the full part number so we can check the equivalent.
- How do I know if this bearing is compatible with my housing?
- Compare the shaft diameter, the overall width and the outer ring type. The PER.GW has a spherical outer ring, so the housing needs to allow for alignment. If you are unsure, send us the dimensions and the housing part number and we will assist.
- What lubrication does this Y-bearing use?
- These bearings arrive factory-lubricated and do not need frequent maintenance. In very demanding environments they can be relubricated as the manufacturer specifies. Do not mix lubricants with different bases without checking first. Write to us if you need more details.
