### FAG Rolling Bearings in Rolling Mills

the radial forces. Roller bearings have a higher load carrying capacity than ball bearings. As a result, the radial forces are supported by roller bearings only, namely cylindrical roller bearings, tapered roller bearings or spherical roller bearings. The material used for the bearing rings and rolling elements is through hardening rolling

### Understanding Rolling Process in Long Product Rolling Mill ...

Nov 27, 2015· Understanding Rolling Process in Long Product Rolling Mill ... Calculation of roll force is important because calculation of torque and power in a rolling mill is based on calculation of roll force. Accurate prediction of roll force for grooved rolling is considerably more difficult than predicting the geometry of the rolling stock.

### POWER IN ROLLING

The ratio λ = [ a/Lp] = [a/√R.∆t] is used to calculate the moment arm 'a' λ =0.5 for hot rolling and 0.45 for cold rolling. The torque is equal to the product of total rolling load and the effective moment arm. Since there are two work rolls Torque Mt = 2P.a Consider two high roll mill as shown in the figure.
