Supply NJ2244 bearing the detailed information: 
 Cylindrical roller bearing characteristics: 
 (1) roller and the raceway line contact or repair offline contact, radial bearing capacity, suitable for heavy duty and shock loading. 
 (2) the friction coefficient is small, suitable for high speed, the speed limit close to the deep groove ball bearings. 
 3 N and NU type axial movement, able to adapt due to thermal expansion or installation error caused by the shaft and the shell of the relative position change for the free side bearing. 
 The machining of the shaft or housing bore higher, and the outer ring axis relative deflection bearing installation should be strictly controlled, so as to avoid contact stress concentration. 
 Inner or outer ring detachable, easy installation and removal. 
 Main purpose: large and medium-sized motors, rolling stock, machine tool spindles, internal combustion engines, generators, gas turbine, gearbox, rolling mill, vibrating screen and hoisting and conveying machinery.
