Double Roller Bearing Pillow Block (DPB) for a 1" diameter linear shaft features two sets of 3 opposing roller bearings while maintaining the standard size open bearing style profile of a Single Roller Pillow Block (SPB).

• Replacement kits of the FUBK Series offer one new roller for each of the 3 rollers in a set
