Double Row Cylindrical Roller Bearing

The double-row cylindrical roller bearing is one separable type bearing and easy to assemble and disassemble. The double-row cylindrical roller bearing has two optional structures: cylindrical bore and tapered bore(suffix K), and two optional designs: NNU and NN. The NN design has an inner ring with two ribs and an outer ring without ribs. The NNU design has an inner ring without ribs and an outer ring with two ribs.

The tapered bore structure can adjust the radial clearance when the bearing is installed. The double-row cylindrical roller bearing allows axial displacement between the shaft and bearing housing and can be used as a non-locating bearing.
