The SKF PER.NK series covers Y-bearing inserts that feature an extended inner ring and set screw locking, designed to fit into bearing units and split plummer block housings. They suit equipment needing smooth rotation and fast shaft attachment, including conveyors, fans and farm machinery. MR Industrial Accessories LLC supplies this line and can help you match the insert to your shaft and housing.
The code breaks down into two parts: PER identifies a Y-bearing insert with an extended inner ring and set screw locking, while NK covers construction variants in the series. Part numbers such as PER.NK-2520, PER.NK-2830 and PER.NK-5025 show how the numbers that follow change with the insert's diameter and width. To pin down the exact size, compare the full code against what your equipment requires.
Typical applications include belt conveyors, bucket elevators, mixers, industrial fans and agricultural equipment. In food processing, cement, cold storage and metalworking plants, these inserts are common because they mount in split plummer block housings or bearing units. That mounting style simplifies maintenance and replacement on production lines where downtime must be kept short.
When choosing an insert, look at three things: shaft diameter, locking method (set screws or eccentric) and the sealing needed for the operating environment. Installation requires a clean, burr-free shaft, and the set screws should be tightened with the correct wrench to avoid slipping. Factory lubrication usually covers initial service, but in humid or dusty conditions, inspect the seal and relubricate if the design permits.
Interchangeability between Y-bearings from different manufacturers is possible when the main dimensions and locking system align. Do not judge by the code alone: compare bore diameter, overall width and seal type. SKF is a global reference, and MR Industrial Accessories LLC carries this line, with the added option of suggesting alternatives if you need a different configuration.
If you have a code like PER.NK-2520, PER.NK-2830, PER.NK-5025 or any other in the series, send it to MR Industrial Accessories LLC by WhatsApp or email. We will provide a quote, and we can also assist in identifying a replacement if the original insert is no longer available.

Frequently asked questions
- What does the PER.NK designation mean on a Y-bearing?
- PER.NK indicates an insert with an extended inner ring and set screw locking. The numbers that follow specify diameter and width. To select correctly, match the full code to your shaft and housing dimensions.
- How do I check if a PER.NK bearing fits my equipment?
- Verify the shaft diameter, insert width and locking type. If the code matches the original, it should fit. If unsure, send a photo or the code via WhatsApp for assistance.
- What lubrication does this bearing type require?
- These bearings typically arrive pre-lubricated. In humid or dusty environments, check the seal and relubricate if the design allows. Avoid mixing lubricants with different bases without consulting us.
