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.
NUP, NFP type
NUP Type：The NUP type of bearing has an outer ring with a guard, one side of the inner ring has a (fixed) single guard, and the other side is a separable flat stop ring. It can withstand a certain amount of two-way axial load.
NFP Type:The NFP type bearing outer ring has a single (fixed) guard on one side, while the other side is a separable flat stop ring, and the inner ring has a guard on both sides. It can also withstand a certain amount of two-way axial load.
This type of structural bearing can limit the displacement of the shaft relative to the bearing seat in both axial directions. Therefore, it is suitable for use as a fixed end 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.
