Detailed Description

The rollers of the cylindrical roller bearing are usually guided by two flanges of a ring. Because this assembly part composed of cage, roller and guide ring can be separated from another ring, the cylindrical roller bearing belongs to separable bearing. This type of bearing can be easily mounted and dismounted. Its advantages are obvious especially when there is interference fits between the inner, outer ring and the axis, housing. This bearing is usually subjected to radial load, only the single-row bearing with inner& outer rings flanges can bear small steady axial load or great intermittent axial load. It has a high requirement on the processing of the fitting parts such as axis and housing bore, etc. The main bearing types produced by KHZZ include: cylindrical roller bearing without inner or outer ring flange (NN type and NU type), four - row cylindrical roller bearing (FC type, FCD type , FCDP type, etc). This type of bearing is widely used in electric motor, chief axis of machine tool, speed reducer, oil driller , steel rolling mill etc
