 Bearing N309 Cylindrical Roller Bearing  


     Cylindrical roller bearing is separable. As their rollers linearly come into contact with inner ring and orter ring with less coefficient of friction, these bearings have very good capacity of radial load, suitable for electric metors, automobiles, transmission shafts, gear shafts and so on. Double row cylimdrical roller bearings are good at the spindles of machine tools.




1, Roller and raceway line contact or repair offline contacts, radial load capacity, suitable to withstand heavy shock load.


2, Friction coefficient, suitable for high-speed, limit speed close to the Deep Groove Ball Bearings.


3, N-type and NU-type axial movement can adapt due to thermal expansion or the mounting error caused by changes in relative positions of the shaft and housing, can make use of the free end support.


4. Higher the processing requirements of the shaft or housing bore bearings installed outer ring axis relative skew should be strictly controlled in order to avoid contact stress concentration.


5, inner or outer ring detachable, easy installation and removal.
