Four-row cylindrical roller bearings are the most widely used bearings in various rolling mill bearings in the metallurgical industry.
The main features are:
1. The bearing has the maximum rated dynamic load value within the effective installation controls;
2. The bearing can be used for high speed;
3. Bearings are allowed to have tighter limit tolerances;
4. The inner ring is allowed to be assembled with the outer components, which is conducive to quick roll change;
5. The bearing can only bear radial load.
Bearing structural form
Based on the three basic structures, there are the following deformed structures:
FC…A type: There is no oil groove and oil hole in the outer diameter, and there is an oil groove on the end face of the outer ring;
FC…B type: There is an oil groove and oil hole on the outer diameter, and an oil groove on the end face of the outer ring;
FC…E type: No oil groove and oil hole in the outer diameter, oil groove on the end face of the outer ring, no center rib on the outer ring, and integral window cage;
FCD…A type: no oil groove and oil hole in the outer diameter, and an oil groove on the end face of the outer ring;
FCD…B type: There is an oil groove and oil hole on the outer diameter, and an oil groove on the end face of the outer ring;
FCD…2LS type: No oil groove and oil hole in the outer diameter, sealed type.
FCDP…E type: There is an oil groove and oil hole on the outer diameter, an oil groove on the inner end face, a pin type cage (hollow roller) or a solid window type cage.
