Cylindrical roller bearings are rolling bearings composed of a disc-shaped roller and a cylinder, which are mainly used to bear radial loads, but can also bear axial loads and torsional loads. The rollers of cylindrical roller bearings are arranged in parallel, and there is a spacer between the rollers, which can effectively avoid the inclination of the rollers or the friction between the rollers, and reduce the increase of rotating torque.
NJ、NF Type
NJ Type :The NJ type bearing has a guard on both sides of the outer ring and a guard on one side of the inner ring. It can withstand a certain amount of unidirectional axial load.
NF Type:The outer ring of NF type has a guard on one side, and the inner ring has a guard on both sides. It also bears a certain amount of unidirectional axial load.
Therefore, this type of structure is suitable for use as a single directional axial positioning bearing.
Advantage
1, with excellent radial load characteristics, strong bearing capacity, suitable for bearing heavy loads.
2, can withstand large axial impact load, and can be kept parallel with the shaft.
3, with excellent radial rigidity, and shaft contact will not produce excessive displacement.
4, at high temperature can also withstand a certain axial load, and has self-lubricating ability.
5, the friction coefficient is small, suitable for high-speed rotation, the limit speed is close to the deep groove ball bearing.
6, cylindrical roller bearings are separated bearings, inner or outer rings can be separated, easy to install and disassemble.
