The SKF PER.GW Y-bearing is a sealed insert with an extended inner ring and set screw locking. It is designed for use in split plummer block housings and take-up frames, supporting rotating shafts in power transmission applications. The insert can be mounted on unmachined shafts and accommodates radial loads with moderate misalignment.
The code PER.GW breaks down into two parts: PER denotes the insert series with an extended inner ring and screw locking, while GW indicates a rubber lip seal that guards against dust and moisture. A suffix such as HYYB covers construction details like the sheet metal cage and outer ring surface treatment. The number that follows, as in PER.GW5209HYYB2, specifies the insert size and shaft diameter. The final digit, here 2, points to sealing or internal clearance variants. When selecting, always confirm the shaft diameter and the housing type.
These inserts are found in belt conveyors, bucket elevators, mixers, mills, and processing equipment across food, chemical, and aggregate plants. They also appear in road machinery and material handling equipment. Their self-aligning capability and ability to run with flexed shafts make them suitable for environments with vibration and continuous radial load.
Selection depends on shaft diameter, radial load, and environmental conditions. The GW seal handles moderate dust and moisture; for frequent washdowns, consider seals with greater protection. During mounting, ensure the set screws are tightened properly on the shaft and the housing is aligned. Factory lubrication typically lasts for the service life, but severe applications may require relubrication. Avoid striking the insert during installation to prevent seal damage.
Y-bearings are interchangeable between brands when outer diameter, width, and locking system dimensions match. SKF, FAG, NSK, and NTN offer equivalent lines, but suffixes may differ. A similar code is not sufficient; compare geometry and sealing type. If uncertain, send us the shaft and housing dimensions and we will help you find the right equivalent.
MR Industrial Accessories supplies SKF Y-bearings. To replace an insert, send the complete code, such as PER.GW5209HYYB2, via WhatsApp or email, and we will provide a quote. We can also assist if the original code is worn or if you need a compatible alternative. Our team responds promptly.

Frequently asked questions
- How do I choose the correct SKF PER.GW Y-bearing?
- You need the shaft diameter and the housing type. The code includes size and sealing variants. If you do not have the code, measure the shaft with a caliper and contact us by WhatsApp.
- What does the GW suffix mean in the designation?
- GW indicates a rubber lip seal that protects against dust and moisture. It suits moderately contaminated industrial environments. For more severe conditions, ask us about other options.
- Are SKF Y-bearings interchangeable with other brands?
- Yes, if the main dimensions and locking system match. Brands such as FAG, NSK, or NTN have equivalent lines, but suffixes change. Always verify dimensions before replacing.
