The ARP series from NTN pairs a cast iron pillow block housing with an insert bearing of the same make, giving maintenance teams a compact support for rotating shafts. It suits transmission and conveying equipment where mounting space is tight and installation has to be straightforward. MR Industrial Accessories supplies this series to customers throughout the United States and Latin America.
Reading the code helps you order correctly. The letters ARP identify the pillow block housing with insert bearing described in the NTN Bearing Units A-21000 catalog, and the figure that follows the letters gives the nominal shaft size, so ARP-1 and ARP-2 sit at different points in the range. Suffixes can point to a particular sealing or locking arrangement. Shaft diameter and the way the unit will be mounted are the two things to settle first.
Typical duty covers food processing, textiles, packaging, material handling and agricultural machinery. Conveyors, bucket elevators, fans and process equipment rely on this style of support because it self-aligns and stands up to constant running. Two bolts through the base hold the pillow block to a flat surface, which keeps assembly and later service work simple.
Selection starts with the shaft diameter and the conditions on site. Insert bearings normally arrive pre-lubricated, with seals that hold grease in and keep contaminants out. Aligning the housing carefully at installation avoids unnecessary axial loading, while regular lubrication and clearance checks help the unit reach a long service life. Our team can walk you through the choice if needed.
Interchange is possible with units from other manufacturers that use the same mounting standard and dimensions. For a replacement, line up the shaft diameter, the hole spacing and the center height, and quote the original code wherever you have it so compatibility is easier to confirm. We can help identify a suitable equivalent.
