Twin Pillow Block - Linear Roller Bearing MTWN-20-OPN for a 20mm Shaft Diameter

Twin (TWN) Roller Bearing Pillow Block for a 20mm diameter shaft. Twin roller pillow blocks cover twice the space on a linear shaft as a single roller pillow block. The twin pillow block has two sets of 3 opposing roller bearings mounted onto this double sized twin housing, as if two Single Roller Pillow Blocks (SPB) were fused together to make a much larger bearing. This differs from the Double (DPB) Pillow Blocks which also have 2 sets of rollers but the DPB rollers are next to each other on a single sized product. 

• Fits a 20mm linear shaft
• No scrapers on each end
• No Top Grease Option
• 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.
• 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
