    Cylindrical Roller Bearings

    Features:
    Cylindrical roller bearings are available in many designs, series and sizes. The majority are single row bearings with a cage. High-capacity bearings, double row bearings, multi-row bearings, single, double and multi-row full complement bearings (without a cage) and split bearings.
    There are different types designated NU, NJ, NUP,N,NF for single-row bearings, and NNU, NN for double-row bearings depending on the design or absence of side ribs. The outer and inner rings of all types are 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.

    Some cylindrical roller bearings have no ribs o either the inner or outer ring. So the rings can move axially relative to each other. These can be used as free-end bearings. Cylindrical roller bearings, in which either the inner or outer rings has two ribs and the other ring has one, are capable of taking some axial load in one direction. Double-row cylindrical roller bearings have high radial rigidity and are used primary for precision machine tools.

    Our company can provide 3 different types of cylindrical roller bearing:
    ■ Single row Cylindrical roller bearings : N , NF, NU, NJ, RN, NUP
    ■ double row Cylindrical roller bearings: NN, NNU
    ■ Full complement cylindrical roller bearing:SL, NNF
