Four row cylindrical roller bearings
Four row cylindrical roller bearing is usually use in rolling mill’s work roll or back-up roll. It mainly take much radial load, which is extensively used on the work roll of wire rod mill, section mill and bloomer mill , as well as the back-up roll of dressing machine, cold rolling mill and hot rolling mill.There are three kinds of structures: FC, FCD, FCDP. There are three grades for tolerance : 0 , 6 , 5.
FC： double outer ring, single inner ring, inner ring without rid;
FCD： double outer ring, double inner ring, inner ring without rid;
FCDP：double outer ring, double inner ring, inner ring without rid
★ Product Features of bearings:
The rollers of the cylindrical roller bearing are usually guided by two flanges of a ring.
Because this assembly part composed of cage, roller and guide ring can be separated from
another ring, the cylindrical roller bearing belongs to separable bearing. This type of bearing
can be easily mounted and dismounted. Its advantages are obvious especially when there is
interference fits between the inner, outer ring and the axis, housing.
This bearing is usually subjected to radial load, only the single-row bearing with inner& outer
rings flanges can bear small steady axial load or great intermittent axial load. It has a high
requirement on the processing of the fitting parts such as axis and housing bore, etc.
★Product Application of bearings:
Cylindrical roller bearings are mainly used for:
- Iron and steel metallurgical industry
- medium and large motor
- combustion engines
- gas tuibine
- machine tool spindle
- speed reducer
- loading and unloading machinery and all kinds of industrial machinery
