Since the roller of cyllindrical roller bearings make line the contact with the raceways, these bearings can support heavy redial loads and are suitable for high speed operation.
Cyllindrical roller bearings come in varoius configuration as shown in the dimensional table. The rollers are guided by the collars of either the inner or outer ring.
Since NU and N type bearings are not provided with a collar on the inner and outer ring. The inner and outer ring can flow axially relative to yhe outer under an axial load. These bearing are most suitable for use on the free side of the shaft.
Bearing type NJ, NUP and NF having collar ring on the both inner and outer ring and can receive a certain amount of axial load. These bearing types are sometimes used on the fixed side of the shafts.
Since Cyllindrical roller bearings are seperable, they can easily mounted or dismounted in cases when interference fits are required.
