Spherical roller bearings cage have two rows of rollers with a common sphered raceway in the outer ring. The bearing cage are self-aligning and consequently insensitive to errors of alignment of the shaft relative to the housing, and to shaft bending. In addition to radial loads, the bearings cages can also accommodate axial loads acting in both directions.PRIME spherical roller bearings cages have a large number of long, symmetrical rollers of large diameter and consequently very high load carrying capacity. These bearings cage have lower operating temperatures or can accommodate heavier axial loads, or can be operated at higher speeds than conventional spherical roller bearings cages.PRIME spherical roller bearings cages are available with cylindrical bore and tapered bore.PRIME supplies adapter and withdrawal sleeves which can be used to mount spherical roller bearings cage with tapered bore on smooth or stepped shafts easily and quickly.
