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 allow the radial clearance to be adjusted when the bearing is installed. The double-row cylindrical roller bearing allows a certain axial displacement between the shaft and bearing housing and can be used as a non-locating bearing.
The advantages of the double-row cylindrical roller bearings are high stiffness and high precision, so they are usually used as main shaft bearings of precision machine tools.
