The ST series safety couplings are available for rated torques of 1,000 -160,000 Nm in four different body sizes and shaft diameters from 40 to 290 mm. The safety couplings are completely backlash and maintenance free.
Large systems are mostly safe in normal operation. Large systems made up of heavy machines must be put back into operation as quickly as possible. This is where mechanical safety coupling offer ultimate protection against destruction of components in the drive train.
The maintenance free design of the safety couplings in combination with its re-engaging function makes a return to normal operation possible in a remarkably small amount of time. The mechanical design of ST safety couplings has distinct advantages over other coupling choices such as shear pin or hydraulic couplings.
RR Fisher will be exhibiting the Series ST Torque Limiters at the upcoming Newcastle - Hunter Coal Mining Expo, to be held at the Newcastle Exhibition Centre. Also on display will be RR Fisher’s comprehensive range of power transmission, vibratory and materials handling equipment.
