    Cylindrical roller bearings Cylindrical roller bearings are separable, easy to mount and dismount especially more outstanding when they are used on bearings requiring interference fit between inner and outer rings with the shaft and housing. Cylindrical roller bearing is contacted with the fair line between the rollers and the raceway, which is of elimination of edge stress. Comparing with the ball bearings, with same boundary dimensions, cylindrical roller bearings have larger radial carrying capacity. Comparing with structure, this type of bearing is more suitable for high speed rotation. Structures 1. N0000 type cylindrical roller bearings without rib on outer ring and NU0000 type cylindrical roller bearings without rib on inner ring These type of bearings can carry large radial load, rotate at a high speed, there is no limit to axial displacement on shaft or housing, but cannot withstand axial load. 2. NJ0000 and NF0000 types Cylindrical roller bearings with ribs on both of inner rings and outer rings NJ0000 and NF0000 types of bearings can allow axial displacement on the shaft or housing and carry little single-direction axial load; NU0000+HJ0000 types and NUP0000 type bearings can allow two-direction displacement within axial clearance range on the shaft and housing and carry little double-direction axial load. 3. RNU0000 Type Cylindrical roller bearings without inner rings. RNU0000 types of bearing are applicable to the parts with limitation on radial size. The shaft surface can be directly used as raceway surface, the hardness, processing precision and surface roughness should be similar to those of ring raceway. 4.NAL0000 type and NNAL0000 type of long cylindrical roller bearings with double ribs on outer rings are applicable to petroleum machinery. 5.Four-row cylindrical roller bearings FC,FCD and FCDP types are mainly applicable to heavy-duty machines, such
