From iron ore to finished steel
In the field of heavy load applications, such as in the steel industry – from iron ore mining to steel rolling mills – mayr® power transmission stands for future-orientated solutions with high performance density as well as high torques and speeds. Where stones burst, hot steel steams and heavy loads have to be held and braked, only robust, resistant and sturdily-dimensioned clutches and brakes can cope with the extreme conditions. In the drive line, they guarantee a secure connection between the shafts, ensure permanently reliable overload protection and can, in case of emergency, absorb peak loads with extremely high friction work: The clutches and brakes by mayr® power transmission ensure maximum operational safety and productivity in the large systems.
