Double Roller Bearing Pillow Block (MDPB-25) for a 25mm diameter shaft in an open bearing style with 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
  
• 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 1 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
