Cylindrical roller bearing are widely used at present market is very hot, and in this process, the field of machine tools use some relatively wide.
Scope of application: this bearing needle roller bearings are used for gearbox, motorcycle, automobile, Cylindrical roller bearing the small end of connecting rod. Gear. Because the cylinder temperature reducer, increase, so the bearing high temperature. With thin and long needle bearing roller (roller length is 3~10 times the diameter, the diameter is generally not more than 5mm), so the radial structure is compact, its diameter size and load capacity compared with other types of bearings at the same time, minimum diameter, especially for radial installation support results in limited size. full complement cylindrical roller bearing According to the use of different occasions, can be used without inner ring bearings or Cylindrical roller bearing and cage assemblies, the shaft neck surface and the surface of shell holes matched with a bearing directly as bearing inner and outer rolling surface, to guarantee load capacity and operating performance and have the same ring bearing, shaft or housing holes raceway surface hardness, the machining precision and the surface quality of bearing ring raceway and similar.
Backing bearings are particularly thick outer ring of the rolling bearing, when used to form a group to be mounted on the shaft of a stationary support rollers. Pressure on the work roll through the intermediate roller and the support roller is passed to the system to the rack through the saddle. Generally used for multi-roll cold rolling mill equipment can also be used for other occasions, such as straightening machine.
