Double Roller Pillow Block Bearing MDPB-25-OPN-S for a 25mm Shaft, Scrapers

Metric version of the scraper fortified Double Roller Bearing Pillow Block (DPB-25) for a 25mm diameter shaft, which has two sets of 3 opposing roller bearings while maintaining the standard size profile of a Single Roller Pillow Block (SPB); thus the term "Double." By contrast, a Twin Roller Pillow Block (TWN) also has two sets of 3 opposing roller bearings, but the TWN blocks are double sized as if they were two SPBs fused together. 

  • Use a floating "F" part number for each opposing normal part number block on a parallel shaft. F-DPB pillow blocks offer flexibility for imperfect alignments
  • Scraper mounted to each end made of spring-tempered beryllium copper that conforms to the shaft diameter
  • No Top Grease Option
  • Double the load capacity of a Single Roller Bearing (SPB) Pillow Block
  • A set of opposing roller bearings consists of 1 fixed side roller, 1 eccentric side roller (to account for any misalignment) and a top support roller
  • FUBK Series replacement kits provide 1 new roller for each of the 3 rollers in a set
  • Order two replacement kits for the 2 sets of this product's opposing bearings
  • OPN signifies an open bearing style
