NU318 EM Cylindrical Roller Bearing
QunMa Cylindrical roller bearing NU318 EM
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.The roller and raceway are line contact.Great radial load rating capacity and can bear heavy load and impact load.
2.Small frictional factor.Suitable for high-speed.Its limiting speed is nearly the same as deep groove ball bearings
3.Inner ring and outer ring are separable which is favorable for assembly and disassembly.
