Double row cylindrical roller bearings are separable bearings, easy to install and disassemble.
Double row cylindrical roller bearings have two types of structure: cylindrical and tapered bores (post code K). There are two main types: NNU design and NN design. The NN design has inner ring with two flanges and outer ring without flange, and the NNU design has inner ring without flange and outer ring with double flanges. Tapered bore structure can adjust radial clearance during installation. A certain of axial displacement between the bearing and the bearing housing is allowed in the double row cylindrical roller bearing, which can be used as the non-positioning bearing.
With good rigidity and high accuracy, double row cylindrical roller bearings are usually suitable for spindle bearings of precision machine tools.
