N type cylindrical roller bearing usually only bear radial forces. Compared with ball bearings of the same size, the radial load capacity is increased by 1.5-3 times, and it has good rigidity and impact resistance. It is especially suitable for rigid supports and short shafts. Axial displacement of the shaft due to thermal elongation and mounting and dismounting requires mechanical attachment of separable bearings.

Single row cylindrical roller bearing is usually only subjected to radial force. Compared with ball bearings of the same size, the radial bearing capacity is increased by 1.5-3 times, with good rigidity and impact resistance. It is especially suitable for rigid supports and short shafts. Axial displacement of shafts caused by thermal elongation and installation and disassembly require machine accessories of separable bearings.

SL bearings are usually guided by two ribs of a bearing ring, cages, rollers and guide rings to form an assembly, generally separable bearings. This kind of bearing is easy to install and disassemble.

The double row cylindrical roller bearing consists of an inner ring, an outer ring, a roller and a cage. The inner and outer rings are connected together by rollers and cages. The roller is cylindrical, by rolling on the inner and outer rings, to achieve the operation of the bearing. The role of the cage is to maintain the position of the roller so that it can be evenly distributed between the inner and outer rings of the bearing. Double row cylindrical roller bearings are compact in structure and large in carrying capacity, which are suitable for high-speed rotation and high load conditions.
