Abstract An effective method of preventing machine failure loss due to accidents that occur during rolling operation and protecting surrounding equipments at such times is to install an over-loading prevention device (torque limiter) in the steel rolling mill. A torque limiter for rolling mills requires such performance features as high accuracy, high durability, high rotational performance both before and after torque release operation, and excellent maintenance features. JTEKT has developed a hydraulic expansion type torque limiter to satisfy these requirements by making use of its experience as a leading manufacturer of driveshafts and bearings.
