The NSK UKP is a mounted pillow block unit: a cast iron housing combined with an insert bearing and an adapter sleeve. It supports rotating shafts in conveyors, agitators, fans and general machinery, and its design suits simple mounting and unmachined shafts. MR Industrial Accessories LLC supplies this line for replacement and new projects, and quotes by part number.
Read the code in three parts. UKP identifies the pillow block housing family with insert bearing; the number after it gives the nominal size, and UKP205, UKP206, UKP207, UKP208, UKP209, UKP210, UKP211 and UKP212 are the most common. The D1 suffix marks construction variants inside the series. The H sleeve that goes with the code, for instance H2305X or H2306X, sets the shaft diameter the unit mounts on. Identifying these components is what lets you pin down the right part.
These units appear in conveying equipment, mixers, blowers, pumps and transmission systems, and in food, chemical, cement and agricultural plants. The pillow block design mounts easily on beds and metal structures. As self-aligning units they tolerate small misalignments and simplify maintenance.
For selection, look at shaft diameter, radial and axial loads, and the environment. The insert bearing seal keeps out dust and moisture, so pick the variant that fits frequent washdowns. Nuts and lock washers tighten the H sleeve, which lets the bearing be fixed at any position along the shaft, and lifetime lubrication in many versions cuts maintenance work. Check that the bed is aligned to avoid stress.
NSK UKP units can be interchanged with other brands using equivalent designations, such as SY or UCP, depending on the manufacturer. Main dimensions usually match, but confirm shaft diameters and mounting holes. Give us another brand's part number and we will point to the compatible alternative, so replacement happens without modifying the equipment. Always verify tolerances and the fixing type.
To request a quote, send the complete part number by WhatsApp or email and the team replies promptly. If the designation is unclear, send a photo or the shaft dimensions and we will help you choose.

Frequently asked questions
- What does the D1 suffix mean on a UKP pillow block?
- It identifies a construction variant within the NSK UKP series, and may relate to seal, cage or material details. Send us the complete part number and we will confirm the characteristics for your application.
- How do I match an H sleeve to my shaft?
- The sleeve must match the shaft diameter where the bearing mounts; H2305X, for example, corresponds to a 20 mm shaft. Check the size before requesting a quote, or send us the shaft size and we will indicate the part number.
- Can an NSK UKP replace a pillow block from another brand?
- Often yes, since main dimensions are usually interchangeable between brands. Still verify shaft diameters, mounting holes and fixing type. Give us the original part number and we will confirm the equivalence.
