The NSK UK3 series is a ball insert bearing whose extended inner ring carries a 1:12 taper, so it seats on an H series adapter sleeve instead of gripping the shaft directly. Once the sleeve and lock nut are tightened, the assembly drops into a split or solid pillow block housing to carry radial loads along with a limited amount of axial thrust. Because the bearing slides onto the sleeve rather than being pressed or heated, it can be fitted and removed with hand tools, which suits routine plant maintenance work. MR Industrial Accessories LLC supplies this line to customers in the United States and Latin America.

Reading the code: the letters UK mark an insert with a tapered bore for adapter sleeve mounting, and the digit that follows is the dimension series, here covering the larger shaft sizes. The D1 suffix denotes a construction variant of the insert itself. After the semicolon comes the sleeve code, which is ordered on its own. The examples UK324D1;H2324, UK326D1;H2326 and UK328D1;H2328 show how insert number and sleeve number pair up.

Typical duty covers equipment where a shaft turns in Y-bearing housings: belt conveyors, bucket elevators, mixers, mills, centrifugal pumps, industrial fans, packaging lines, and machinery in food and cement plants. Adapter sleeve mounting is especially useful on long shafts or in positions that are awkward to reach, since the bearing can be adjusted along the shaft and released without a press.

Selection comes down to three things: shaft diameter, whether the load is radial, axial or combined, and the surrounding conditions. The insert seal keeps out dust and moisture, so in wet or gritty areas it pays to confirm which seal type the application needs. For mounting, clean the shaft and taper, tighten the lock nut with the correct wrench, then check internal clearance. The factory grease charge can be topped up with a compatible grease, and lining the insert up with the housing avoids parasitic stresses.

Inserts from different makers in the UK3 series share the same basic dimensions and taper, but sealing, tolerances and suffixes are not always identical. Send a code from another brand, or a part you cannot identify, and we will quote it and point out a compatible option. Always check interchangeability against the equipment drawing or data sheet, particularly where axial load or higher speed is involved.

To get a quote, message us the full insert and sleeve code, for example UK324D1;H2324, or simply the shaft and housing dimensions. We reply promptly and can advise on mounting and lubrication. H adapter sleeves, lock nuts and greases can be added to the same inquiry.
