The NSK UK series is a ball bearing insert whose inner ring has a 1:12 taper, so it mounts on the shaft through an adapter sleeve. It sits in split plummer block housings and take-up units, carrying radial loads in transmission equipment. Because the sleeve does the fastening, installation and removal are straightforward when maintenance windows are short. MR Industrial Accessories supplies this series for applications where alignment and secure clamping matter.

Reading the code tells you both size and mounting method. In UK217D1, the UK prefix identifies the tapered-bore insert, 217 sets the size, and D1 covers sealing and cage variants. The matching sleeve is HA2317X. The same logic applies across the range: UK218D1 pairs with HA2318X, and UK318D1 with HA2318X, with the UK2 or UK3 series determining the size.

Typical duty includes conveyors, elevators, mixers, mills and other transmission drives in food, cement, mining and process plants. The design handles radial loads and moderate axial loads, and with the right seal it tolerates dusty or humid conditions. Mounting is in split plummer block housings or take-up units, which suits lines where fast intervention is expected.

Selection starts with shaft diameter, then load type and environment. The seal has to keep contaminants out, lubrication must suit the duty, and internal clearance must match the application. When you mount on a tapered sleeve, work clean and tighten in a controlled way to avoid distorting the ring. Alignment between housings also has a direct effect on service life, so check it before running. We can help you match the sleeve and the mounting tolerances.

Equivalents from other brands can replace UK series inserts when dimensions and taper agree. Always confirm the full part number and the sleeve dimensions. If you only have another brand's reference, we can point you to a compatible option. Seals and cages sometimes differ, so a specialist should confirm interchangeability rather than assume it.
