KOYO Rollway Cylindrical Roller Bearing NU2314E with 70X150X51MM
Single row cylindrical roller bearings
This type of bearings are manufactured in several different designs, the main difference being in the configuration of the flanges. The most popular are the NU, N, NJ and NUP designs. Cylindrical roller bearings can accommodate heavy radial loads and high speeds.Some with different strcuture of ribs can also bear one way ot two way axial load.NN and NNU double row cylindrical roller bearings have a low cross section, high load carrying capacity and high stiffness,therefore it is mostly used in machine tool spindle stands.FC,FCD,FCDP four row cylindrical roller bearings with large capacity of radial load,mostly applied in rolling mill and heavy machine
This type of bearings is separable.As their rollers linearly come into contact with inner ring and outer ring with less coefficient,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 spindles of machine tools.
FCDP: double outer rings, only have center flange, but with loose rib, double inner ring, inner without flange.
