Four row bearing
Four row cylindrical roller bearings are mainly used in cold, hot-rolled machine, Bloom machine, such as rolling mill machinery, bearings for the separation structure, bearing rings and rolling body components can be easily separated, therefore, the bearing cleaning, inspection or installation and disassembly is very convenient.
FC-type bearings are made up of two outer rings and one inner ring, each side of which has a middle retaining edge and an inner ring without flanges.
FCD type bearings are actually made of two of nn-type bearings.
FC-Type and FCD-type bearings can allow the shaft to produce two-direction displacements between the bearing housings. Therefore, this kind of structure is suitable for the swimming end bearing. The cage of the type bearing is more than 13:58 of the vehicle system.
