Twin (TWN) Roller Bearing Pillow Block designed for a 2" diameter shaft covers twice the space on a linear shaft compared to a single roller pillow block (SPB). The twin pillow block features two sets of 3 opposing roller bearings mounted in a larger open bearing twin housing, as if two Single Roller Pillow Blocks (SPB) were fused together. This differs from Double (DPB) Pillow Blocks, which also have two sets of 3 rollers, but the DPB rollers are positioned side by side on a single-sized product.

• The twin TWN blocks, like the double DPB blocks, have two sets of 3 opposing rollers that double the load capacity of a Single Roller Bearing Pillow Block (SPB) which has just 1 set of 3 opposing rollers
  
• Each set of roller bearings consists of 1 fixed side roller, 1 eccentric side roller and a top support roller
  
• Floating pillow blocks should be used for each opposing block when running on parallel shafts.
• No scrapers (-S) and no lubrication port (-TG) - for both of these, choose the part number with -STG
  
• The eccentric opposing roller in each set helps account for any small misalignment
• Replacement kits of the FUBK Series include just one set of 3 opposing roller bearings, so be sure to buy two FUBK replacement kits for this product and other double or twin roller bearing pillow blocks
