Twin Roller Pillow Block - Linear Bearing TWN-08-OPN 1/2" Shaft Diameter

Twin (TWN) Roller Bearing Pillow Block designed for a 1/2" 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 twin housing with an open bearing style, 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.

• Floating roller pillow blocks should be used for each opposing block when running on parallel shafts
• 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
  
• No scrapers, no lubrication port
  
• 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
