NTN Cylindrical roller bearing

NTN cylindrical roller and raceway are linear contact bearings. Large load capacity, mainly bearing radial load. The friction between the rolling element and the retaining edge of the ferrule is small, which is suitable for high-speed rotation. According to whether the ferrule has retaining edge or not, it can be divided into single row cylindrical roller bearings such as Nu, NJ, NUP, N and NF, and double row cylindrical roller bearings such as NNU and NN. The bearing is a separable structure of inner ring and outer ring

for cylindrical roller bearings without flange on the inner or outer ring, the inner ring and outer ring can move relatively axially, so they can be used as free end bearings. A cylindrical roller bearing with double retaining edges on one side of the inner ring and the outer ring and a single retaining edge on the other side can bear a certain degree of axial load in one direction. Generally, steel plate stamping cage or copper alloy turning solid cage are used. However, some use polyamide formed cages
