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. Among them, the four rows of cylindrical roller bearings are mainly used in cold, hot binding machine, billet machine and other rolling machine machinery, bearings are separated structure, shaft sleeve ring and rolling body components can be easily separated, therefore, the bearing is clear, hard check goods installation and disassembly are very convenient.
Type FC and FCD :
The FC bearing is composed of two outer rings and an inner ring, and the two sides of the outer ring have a middle guard edge in the middle, and the inner ring has no guard edge.
The FCD bearing is actually a combination of two NN bearings.
The FC and FCD type bearings allow for two axial shifts between the shaft and the bearing seat. Therefore, this kind of structure is suitable for traveling end bearings. The cage of this type of bearing adopts a cart-made solid cage.
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.
