For shafts that need a bearing unit which goes on and comes off without a press, the NSK UK series insert bearing is a ball bearing with an extended inner ring and a tapered bore. It mounts on an adapter sleeve inside a split housing. This makes it a practical choice where alignment and load capacity matter and where maintenance access is limited.
Reading the code: UK marks the tapered-bore insert family. The digit group after it refers to the adapter sleeve diameter, with UK2 covering the smaller metric sizes and UK3 the larger ones. The D1 suffix denotes the tapered bore version with the slot for the adapter sleeve. Insert and sleeve are matched by size, so a UK211D1 goes with an HE2311XY. That pairing sets the fit on the shaft.
Typical applications include conveyors, belts, elevators, mixers, mills and other process equipment, as well as packaging lines, agricultural machinery and material handling gear. The main benefit of the UK design is that the adapter sleeve allows installation and removal without a press, which keeps maintenance simpler on equipment that is hard to reach.
When selecting, start from the shaft diameter and the matching HE adapter sleeve. The insert sits in the split housing and the sleeve is tightened with the lock nut. Check housing alignment and lubrication, and note that these inserts have lip seals that hold grease in and keep dust out. In very dirty or wet areas, inspect the seal and review the greasing interval more often. Keep the adapter sleeve clean and free of burrs, since it seats on the taper.
UK inserts are interchangeable across brands when series, diameter and adapter sleeve type line up. Cross-referencing is done by size and by the HE sleeve number. If you only have another brand's reference, send it and we will match the NSK insert. Because fit depends on housing and shaft tolerances, verify dimensions before replacing.

Frequently asked questions
- What does UK indicate on an insert bearing?
- It identifies inserts with a tapered inner ring that mount on adapter sleeves. The following number gives the sleeve diameter, UK2 for smaller sizes and UK3 for larger ones, and D1 marks the tapered-bore variant.
- Which HE adapter sleeve fits my UK insert?
- It depends on the shaft diameter and the insert series. A UK211D1, for instance, uses an HE2311XY. Send us the insert part number and we will confirm the sleeve.
- Can NSK UK inserts replace other brands?
- Yes, when series, diameter and adapter sleeve type match, since the dimensions are standardized. Send the other brand's part number and we will quote the NSK equivalent.
