Twin (TWN) open linear cam roller bearing pillow block for 2" shafts (with scrapers at each end), spanning twice the length of a single unit. This linear bearing uses two sets of three opposing cam roller bearings mounted in an extended housing—effectively two Single Roller Pillow Blocks (SPB) combined into one larger bearing. Unlike the Double (DPB) pillow block, which also has two roller sets, the DPB places them side-by-side within a standard-length housing.

• Twin (TWN) blocks, like Double (DPB) blocks, feature two sets of three opposing rollers providing approximately twice the load capacity of a Single Roller Bearing Pillow Block (SPB), which contains one set
• Each roller set includes 1 fixed-side roller, 1 eccentric-side roller, and 1 top support roller
• The opposing eccentric roller compensates for minor misalignment
• For parallel shafts, use floating pillow blocks on the opposing shaft to accommodate misalignment
• Scrapers are mounted at both ends and are made from spring-tempered beryllium copper.
• No top grease option available
• FUBK Series replacement kits include one set of three opposing rollers; purchase two kits for TWN and DPB roller bearing pillow blocks
