Double row cylindrical roller bearing

Double row cylindrical roller bearings have cylindrical and conical bore (rear designation K) two structures. There are two main types :NNU design and NN design. The NN design has double baffle in the inner ring and no baffle in the outer ring. The NNU design has no flanges in the inner ring and double flanges in the outer ring. The conical hole structure can adjust the radial clearance during installation. Dual row cylindrical roller bearings allow a certain axial displacement between the shaft and the bearing seat and can be used as non-positioning bearings. This kind of bearing has the advantages of compact structure, large rigidity, large bearing capacity and small deformation after loading, especially suitable for machine tool spindle support.

 

Two - column cylindrical roller bearing holders are usually car - made solid holders.
