Floating Twin (TWN) Roller Pillow Block Bearing with scrapers for a 1.25" Diameter Shaft. Twin pillow blocks cover twice the space on a linear shaft as a single version. This pillow block has two sets of 3 opposing roller bearings mounted on 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. 

• 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
• The eccentric opposing roller in each set helps account for any small misalignment
• Scraper mounted to each end made of spring-tempered beryllium copper that conforms to the shaft diameter
• No Top Grease Option
  
• 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.
• OPN signifies an open bearing style
  
• The Float designation means that, if two parallel shafts are not perfectly aligned with each other, the pillow block bearings on one of the shafts should be of the Float variety which will allow some leeway to overcome the minor misalignment.
