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.
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. 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.
4. The inner ring or outer ring can be separated, easy to install and disassemble.
