NSK UK2 and UK3 insert bearings are ball bearings with an extended inner ring and a 1:12 taper. They mount on an adapter sleeve, which lets you fit them into split plummer block housings or take-up units. These inserts suit transmission shafts where a self-aligning, easy-to-install bearing unit is needed. MR Industrial Accessories supplies this line and can help you pair the correct insert with its sleeve.
Reading the code helps you order correctly. UK means a tapered-bore insert for a sleeve. The first digit, 2 or 3, sets the outer diameter series, and the next two digits give the shaft diameter. The D1 suffix marks NSK sealing and tolerance variants. Match the sleeve by shaft number: UK208D1 goes with HS2308X, UK209D1 with HS2309X, and UK213D1 with HS2313X. The UK3 series also draws on 23-series sleeves, so UK308D1 uses HS2308X, UK309D1 uses HS2309X, and UK313D1 uses HS2313X.
Typical applications include conveyors, belts, elevators, mixers, fans, centrifugal pumps, and agricultural machinery. Anywhere you want fast mounting and good self-alignment, these inserts are a practical choice. Because they are standard components, they help standardize maintenance and cut down the variety of spare parts you keep on hand.
When selecting, check the shaft diameter, the load type (radial, axial, or combined), and the operating environment. D1 sealing guards against dust and moisture. In frequent washdowns or with fine particles, consider additional seals. Mounting on a tapered sleeve calls for clean surfaces, the specified lubrication, and tightening the lock nut with the right wrench to reach the correct internal clearance. Careful housing alignment also extends bearing life.
NSK UK2 and UK3 inserts interchange dimensionally with other brands that use the same nomenclature and HS sleeves. If you have a code from another brand or an unidentified part, MR Industrial Accessories can point you to a compatible alternative. Always confirm shaft diameter, series, and sleeve type before replacing, since small differences in sealing or tolerance can affect performance.

Frequently asked questions
- What is the difference between a UK2 and a UK3 insert?
- For the same shaft diameter, the UK2 series has a smaller outer diameter than the UK3. That affects load capacity and the housing it fits. Both use a tapered sleeve, but the HS sleeve combinations differ by series and diameter.
- How do I know which HS sleeve matches my UK insert?
- Choose the sleeve by shaft number and insert series. For example, UK208D1 takes HS2308X, and UK308D1 also takes HS2308X, though the insert outer diameter changes. Verify the complete insert code and the sleeve you have before requesting a quote.
- Can I replace a UK insert from another brand with an NSK one?
- Yes, if the series, shaft diameter, and sleeve type match. NSK UK2 and UK3 inserts are dimensionally equivalent to other brands that use the same nomenclature. If you are unsure, send the original part code and we will indicate the equivalent.
