OEM No/Model: NU2208E
This type of bearing is separable. As their rollers linearly come into contact with inner ring and outer ring with less coefficient of friction, these bearings have very good capacity of radial load, suitable for electric motors, automobiles, transmission shafts, gear shafts and so on. Double row cylindrical roller bearings are good at the spindles of machine tools.
It can be divided into following type: Single row, double row and four row cylindrical roller bearings.
According to the difference of ferrule block, single row cylindrical roller bearings can be separated as N series, NU series, NJ series, NF series, and NUP series and so on. Meanwhile, cylindrical roller bearings also have a high capacity of enduring radial load, it can also endure certain amount of unilateral or bidirectional axial load.
Double row cylindrical roller bearings as NN series and NNU series always with features of compact structure, high rigidity, high carrying capacity, very small distortion even with heavy load, so it mainly used as the supporting of principal axis of machine tool. FC series, FCD series and FCDP series four row cylindrical roller bearings have high carrying capacity of radial load, so it mainly in these heavy machine as rolling mill and so on.
