Torque limiter when the overload or mechanical failure which led to more than the required torque setting, the form of restrictions on its transmission system by the spin torque transmission, when the overload on its own to restore the situation after the link. This will prevent mechanical damage, to avoid loss of expensive downtime. Torque limiter using spring-type friction surface of the load to adjust the nut or bolt spring, and the default of its sliding torque. Range of applications: electronic equipment industry, automated production lines, conveyor and other industries.
