The NTN UCPX pillow block is a mounted assembly that pairs a cast iron housing with an insert bearing secured by set screws. It supports rotating shafts where alignment is straightforward and installation time matters. Belt drives, conveyors and agricultural or industrial machinery commonly use this configuration. MR Industrial Accessories supplies this line to customers across the United States and Latin America.
In the UCPX code, the letters identify the pillow block series with insert bearing. The digits that follow indicate the bearing size, which changes from one part number to the next. A hyphen and suffix may denote shaft diameter or mounting variants; the D1 ending refers to a sealing type. When reading a designation, match the shaft diameter and mounting style your equipment requires.
Typical installations include belt conveyors, mills, mixers, fans and process equipment in food, chemical and aggregate plants. Machine tools and chain or belt transmission systems also rely on these blocks for economical, reliable shaft support. The housing accepts radial, axial or combined loads, and the D1 seal adds protection against dust and moisture in dirty environments.
Selection starts with the shaft diameter and the load type. During assembly, mount the block on a flat, rigid base and align it with the shaft to prevent stress. The insert bearing is lubricated for life, so maintenance focuses on checking set screw tightness and seal condition. If you have a part number from another source, send it to us; interchangeability depends on main dimensions and shaft diameter, not on the exact designation, and we can suggest an equivalent.
To request a quote, send the complete part number via WhatsApp or email. If the exact variant is unclear, provide the shaft diameter and working conditions and we will identify the corresponding reference. Our team replies promptly and can help you choose.
For example, UCPX05 fits a 25 mm shaft and UCPX06 a 30 mm shaft. Measure with a caliper and confirm the designation before ordering. If you need guidance, send us the measurement and we will quote the exact reference.
