Double Row Cylindrical Roller Bearing

Double row cylindrical roller bearings have small cross-section, high load capacity and high rigidity. Therefore, these bearings are mainly used for machine tools, rolling stands, plastic drums, grinding machines and large gear boxes. There are two basic type of double row cylindrical roller bearing. They are NNU type bearings and NU type bearings which can be separated. These bearings have cylindrical bores and tapered bores, the NN type bearing are generally have cylindrical bores. Double row cylindrical roller bearings are mainly used for machine tools, rolling stands, plastic drums, grinding machines and large gear boxes.
