Quick Details

Cylindrical roller bearings

?? Cylindrical roller have linear contact with raceway, and the bearings can carry heavier radial load. Applications are found in situations characterized by heavy load and shock load and also high rotation speed.

? The N type and NU type bearings can be movable along the shaft. They can adapt to the position changes between the shaft and housing caused by the thermal expansion or the mounting error and are most suitable for free end shafts.

? NJ and NF types can accept certain axial load in one direction, and NH and NUP types can accept certain axial load in two directions.

? Inner ring and outer ring can be separable, and they are convenient to mount and dismount.

? The rigidity in carrying radial load in the NNU and NN types makes them applicable for machine tool spindles.

? FC, FCD and FCDP types can carry comparatively heavy radial load and are mainly applied for mill rolls.

? Applications of these bearings are mostly found in middle-sized and large-sized motors, electricity generators, internal combustion engines, gas turbines, machine tool spindles, deceleration devices, unloading and lifting machines and other industrial machines.

Single-row cylindrical roller bearings

? NU type and N type cylindrical roller bearings allow the shaft to move in the axial direction within certain limits in relation to the housing. Therefore, they can be used as bearings on the free end of the shaft.

? NJ type and NFP type cylindrical roller bearings can carry the axial load within certain limits in double directions.

Double-row cylindrical roller bearings

? There are cylindrical bored and taper bored cylindrical roller bearings. There may be lubricating holes or grooves on the outer rings of these bearings.

? Mostly these bearings are used in machine tool spindles, but they can be used other situations too.

Four -row cylindrical roller bearings

Four -row cylindrical roller bearings can carry much heavier radial load and shock load.

They have higher manufacturing precision and can be used to meet high rotational speed requirement. Mostly these bearings are used in the rolling mills and some other cases.
