Cylindrical roller and raceway for the line of contact bearing. Large load capacity, mainly bear radial load. Ring wall and rolling friction is small, suitable for high-speed rotation. According to the ferrule has without ribs, can be divided into NU, NJ, NUP, N, NF single row cylindrical roller bearings, and NNU, NN double row cylindrical roller bearing. The bearing 's inner, outer ring can be separated.

The inner or outer ring without rib of cylindrical roller bearing, the inner ring and the outer ring can axially move relatively, so it can be used as free end bearings. On one side of the inner ring and the outer ring of the double rib, the other side of the ferrule has a single rib of cylindrical roller bearings, can be a direction of the axial load to bear a certain degree of. General stamping steel cage, or copper alloy machined solid cage. But there are also a part of the use of polyamide forming the holder.

Single row cylindrical roller bearings are usually only by radial force, compared with the same size ball bearings, radial load carrying capacity is increased by 1.5-3 times, good rigidity, impact resistance, it is especially suitable for rigid support, and the short supporting axle, thermal elongation caused by axial displacement of the shaft and the mounting and dismounting need separation machine bearing accessories. Mainly used for large motor spindle, before and after, engine bearing, passenger train carriage axle bearing, crankshaft of diesel engine, automobile and tractor gear box.

Single row cylindrical roller bearing, which comprises an outer ring, an inner locking ring and cage. An annular groove is arranged between the outer surface of the stress of the outer ring, a plurality of locking ring groove on the outer wall of the outer ring, the locking ring shape and size and the locking ring groove shape and size to adapt. Locking ring groove is provided with a locking ring. The outer wall of the torus and stress groove corresponding part is provided with an annular retainer guide groove. The utility model has the advantages of convenient assembly, large bearing load, the advantages of high limiting speed, high reliability, long service life etc..

Cylindrical roller thrust bearings are often combined into high rigidity bearing configuration, can withstand heavy loads and vibration loads without difficulty. This bearing can bear great single axial load, but cannot bear radial load, they are not automatically aligning ability.

Thrust cylindrical roller thrust bearings can be split into cylindrical roller and cage assemblies, shaft ring and ring.

The 811 series and 812 series of cylindrical roller thrust bearings and the thrust cylindrical roller and cage assemblies, shaft ring and ring, the most important part is the thrust cylindrical roller and cage assemblies.
