Characteristics:
1.Roller and raceway are in line contact or downline contact, radial bearing capacity is large, suitable for bearing heavy load and impact load.
2.Small friction coefficient, suitable for high speed, limit speed close to deep groove ball bearings.
3.N type and NU type can be moved in axial direction, can adapt to the change of the relative position between the shaft and the shell caused by thermal expansion or installation error, can be used as free end support.
4.The processing requirements for shafts or seat holes are high. After bearing installation, the relative deviation of the outer ring axis should be strictly controlled to avoid contact stress concentration.
5.The inner ring or outer ring can be separated, easy to install and disassemble.
Application:
Large and medium-sized electric motors, rolling stock, machine tool spindles, internal combustion engines, generators, gas turbines, reduction boxes, rolling mills, vibrating screens and lifting and transportation machinery, etc.
Composition: single row cylindrical roller bearing, including outer ring, inner ring locking ring and cage.
Advantages: convenient assembly, large load bearing, high limit speed, strong reliability, long service life and other advantages.
Application: mainly used for large motor, machine tool spindle, engine front and rear support shaft, train and bus box shaft support, diesel engine crankshaft, automobile tractor gearbox, etc.
