Description
SKF PER.W5204RRY74-A is a y-bearing (insert bearing) reference, within Bearings. Request a quote for PER.W5204RRY74-A via WhatsApp or email with the quantity you need; we respond promptly with lead time and equivalents.
The SKF PER.W RR-A series Y-bearing is an insert with a spherical outer ring and set screw locking system, designed to be mounted in split or pillow block housings. It is used in power transmission equipment where compensating for misalignment and simplifying mounting are required. Its sealed design makes it suitable for environments with moderate dust or humidity. MR Accesorios Industriales carries this line as part of its bearing catalog for industry.
The PER.W RR-A designation is interpreted in parts: the PER prefix indicates it is a Y-bearing from the SKF family; the W indicates the dimension series; RR corresponds to the sealing type, with contact lips; the final Y refers to set screw locking on the inner ring. The examples PER.W5204RRY74-A and PER.W5204RRY77-A share the number 5204, which defines the insert size, and the suffixes 74 and 77 identify construction variants within the same series.

These bearings are used in power transmission equipment such as conveyors, elevators, mixers and industrial fans. In the Argentine market, they are common in food, cement, mining plants and in the manufacturing industry in general. Their ability to support radial loads and some axial thrust makes them versatile for transmission shafts at moderate speeds. MR Accesorios Industriales offers them for replacement and new projects.
To select the right Y-bearing, take into account the shaft diameter, the type of load and the environmental conditions. The RR seal with contact lips protects against contaminants and retains lubricant, but verify that it is compatible with the operating speed. Internal clearance and alignment are critical: the spherical outer ring allows compensating for small misalignments, but forced mounting can damage the seals. Lubricate according to the manufacturer's recommendations and secure the set screws with the proper torque.
Regarding equivalences, Y-bearings from different brands can be interchanged if the main dimensions and the locking type match. However, not all suffixes are equivalent: sealing and locking codes vary between manufacturers. To replace a PER.W5204RRY74-A or PER.W5204RRY77-A, compare bore, outside diameter and width, as well as the locking system. Consult our technical team to validate interchangeability.

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