The NSK UK series insert bearing is a ball bearing with an extended inner ring and a 1:12 taper, secured to the shaft by an HS series adapter sleeve. It fits split plummer block housings and bearing units to handle moderate radial and axial loads. This makes it a practical choice for transmission, conveying and general machinery where mounting simplicity and sealing against contaminants matter.

Reading the UK code: the letters UK denote the tapered insert bearing, the first digit gives the diameter series (UK2 for series 2, UK3 for series 3), and the last two digits indicate the shaft diameter in millimeters. Match the HS adapter sleeve to both the shaft diameter and the bearing series. This pairing lets you fix the bearing on a cylindrical shaft without extra machining.

In US plants, these inserts appear in belt conveyors, bucket elevators, mixers, mills, packaging lines, and equipment for food or cement processing. You also find them in agricultural machinery such as seeders and harvesters, and in aggregate plants. They tolerate slight misalignment, and their seals suit dusty or moderately humid conditions. MR Industrial Accessories supplies this line for replacement and new projects across the United States and several Latin American countries.

When selecting the insert, consider shaft diameter, expected radial and axial load, and the operating environment. The seal keeps out dust and splashes; if washdowns are frequent, look into additional sealing. Standard internal clearance works for normal applications; for high temperatures or combined loads, ask about available variants. Mounting with the HS adapter sleeve involves cleaning the cone, fitting the lock nut and lock washer, and tightening with the proper wrench. Factory lubrication is typically enough, but in continuous duty relubrication should follow the duty cycle.

For equivalents, tapered insert bearings interchange between brands as long as the series and shaft diameter match: another brand can replace the NSK unit if dimensions and fixing type are respected. HS adapter sleeves also interchange among manufacturers that follow the standard. If you have an unidentified part, we can compare measurements to find a suitable equivalent. Always verify shaft diameter and adapter sleeve pitch before replacing.
