Description:
Rolling Mill bearings are mainly double-row angular contact ball bearings, four-point angular contact ball bearings, double-row taper roller bearings, four-row cylindrical roller bearings
Roll mill bearings accommodate extreme radial loads and in order to carry huge draught pressure, the journal diameter of the mill roll should be broader, in the mean time, the external diameter of bearings couldn't be too bigger. Thus, roll neck bearings must improve the loading capacity of bearings according to the width of the mounting position and always adopt multi-row bearings.
FC: Double outer races, single inner race, no rib on the inner race
FCD: Double outer races, double inner races, no rib on the inner race
FCDP: Double outer races, with only middle rib on and loose rib on the outer race, double inner races, no rib on the inner race.

Applications:
They are suitable for the accommodation of combined (radial and axial) loads and can locate a shaft
axially in both directions with a given axial clearance or a given preload. Their main use is in gearboxes,
hoisting equipment, rolling mills and machines used in the mining industry, e. G. Tunnelling machines.
FEATURES:
1. The maximum dynamic load rating can be achieved with a limited mounting space;
2. They are applicable for high speed operation
3. They permit more accurate limiting tolerances
4. Bothe inner ring and outer ring assembly(outer ring with a set of rollers) are interchangeable, which is helpful for quick roll replacement
5. They can only accommodate radial load
