Rolling mill gearboxes

Mill gearboxes and drive trains

Nobody watches the gearbox. Until it stops.

In most mills, every kilowatt that reaches the rolls passes through a gearbox.

Hour after hour, with a shock load each time a billet bites. A mill gearbox has to be built for that moment, not for an average day.

BEISCO designs and manufactures mill gearboxes around the torque, speed and layout of your stands, so the drive train is matched to the mill rather than to a catalogue.

Send us the motor data and the torque at the stand. We will design the gearbox.
