A UKP unit is a shaft support that pairs a cast iron pillow block housing with a tapered bore insert bearing, held on the shaft by an adapter sleeve. It suits drive shafts where a solid, self-aligning mounting is needed and assembly should be straightforward. MR Industrial Accessories LLC supplies this NSK line to customers in the United States and Latin America, quoting by part number through WhatsApp or email.

Reading the code helps when ordering. UK points to the tapered bore insert bearing used with an adapter sleeve, P to the split pillow block housing with two mounting holes, and the digits give the assembly size. Examples include UKP211D1 and UKP311D1, where D1 marks the insert design variant. The sleeve carries its own HE reference, such as HE2311XY, in which X stands for the shaft diameter in inches and Y for the sleeve thread. Quote requests should include both references.

Typical applications include belt conveyors, bucket elevators, mixers, mills, packaging lines and process lines in food, chemical and aggregate plants, plus material handling equipment, blowers, centrifugal pumps and agricultural machinery. Mounting on a flat base absorbs slight misalignment, which helps when the frame is not perfectly rigid or the shaft deflects. It is also a practical way to support long shafts that need several support points.

Selection starts with the shaft diameter, which determines the HE adapter sleeve. The housing should sit on a flat, machined surface, with both mounting bolts tightened evenly so the base is not distorted. Tighten the sleeve nut with the correct wrench until internal clearance is right. The insert is greased at the factory; afterwards, follow the machine's lubrication schedule. For dusty or wet conditions, review the insert sealing and the housing type.

Brands use different nomenclature for the insert, the housing and the sleeve, so interchangeability is settled by shaft diameter, center height, hole spacing and sleeve type rather than the part number alone. Send an unidentified part or another brand's reference and we cross-reference it to the equivalent. If you need a variant that is not listed, message us with the part number or model.

For a quote, send the pillow block and adapter sleeve part numbers, or simply the shaft size and the distance between the base mounting holes. We will identify the matching NSK unit for your equipment. We can also advise on fitting the tapered insert and setting the adapter sleeve so the unit runs aligned.
