The SKF PER.W RR-A series is a Y-bearing insert that features a spherical outer ring and uses set screws to lock onto the shaft. It fits into split or pillow block housings and is commonly found in power transmission setups where minor misalignment needs to be absorbed and installation kept simple. The sealed construction handles environments with moderate dust or moisture. MR Industrial Accessories supplies this line as part of its bearing range for industry.
Reading the code helps you pick the right replacement. PER identifies a Y-bearing from the SKF family; W gives the dimension series; RR stands for the contact lip seal; Y means set screw locking on the inner ring. In examples like PER.W5204RRY74-A and PER.W5204RRY77-A, the shared 5204 sets the insert size, while 74 and 77 are construction variants in the same series.
Typical applications include conveyors, elevators, mixers and industrial fans. These inserts support radial loads and some axial thrust, which makes them suitable for transmission shafts at moderate speeds. They are common in food, cement, mining and general manufacturing plants. MR Industrial Accessories offers them for both replacement and new projects.
When selecting a Y-bearing, consider shaft diameter, load type and operating conditions. The RR seal with contact lips keeps contaminants out and lubricant in, but check that it suits your speed. Internal clearance and alignment matter: the spherical outer ring compensates for small misalignments, yet forcing the mounting can harm the seals. Follow the manufacturer's lubrication guidance and tighten the set screws to the correct torque.
Interchangeability between brands is possible when the main dimensions and locking method align, but suffixes are not always equivalent because sealing and locking codes differ. To replace a PER.W5204RRY74-A or PER.W5204RRY77-A, compare bore, outside diameter and width, plus the locking system. Our technical team can help confirm compatibility.

Frequently asked questions
- What does the PER.W5204RRY74-A designation mean?
- PER indicates an SKF Y-bearing; W is the dimension series; 5204 defines the size; RR is the lip seal; Y the set screw locking; 74 a construction variant; and -A an internal suffix. Each part identifies specific insert characteristics.
- Is this Y-bearing compatible with housings from other brands?
- Yes, if the insert dimensions match the housing bore. Check outside diameter, width and locking system. Standard split plummer block housings usually accept inserts from different brands when they follow standardized dimensions.
- How are PER.W RR-A series Y-bearings lubricated?
- These bearings typically come factory-lubricated and sealed. If your application needs relubrication, use the channel in the outer ring and apply a grease compatible with the original. Follow SKF's instructions to avoid damaging the seals.
