Double Row Cylindrical Roller Bearing

Double row cylindrical roller bearings have two structures: cylindrical inner bore and conical inner bore (the bearing code is added with K). The bearing has the advantages of compact structure, high rigidity, large carrying capacity, and small deformation after being loaded. It is especially suitable for the support of machine tool spindles. The conical inner hole can also play the role of micro-adjustment of the clearance, and can simplify the structure of the positioning device and facilitate installation and disassembly. Commonly used Double row cylindrical roller bearings are: NN, NNU, NNF type.
