R+W Coupling Technology has just released a new range of safety couplings - the

• Series ST Torque Limiters

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 couplings are absolutely backlash and maintenance free.

For the most part, large systems are safe in normal operation.  But what happens beyond the scope of normal operation?  What happens when an individual component breaks due to previously undetected material fatigue?   It is the profitability of the entire system which is at stake.  Large systems made up of heavy machines must be put back into operation as quickly as possible.  This is where a mechanical safety coupling from R+W Coupling Technology offers maximum protection against destruction of components in the drive train.  The coupling‘s maintenance free design, above all in combination with its re-engaging function, makes a system‘s return to normal operation possible in a remarkably small amount of time.  The mechanical design of the ST Safety Coupling has distinct advantages over other coupling choices such as shear pin or hydraulic couplings.  To read a full description of how the ST Series can help prevent expensive machinery downtime, please click on RWSTPressRelease.pdf.   To view the technical specifications of the ST Series range please click on RWSTTorque-Limiters.pdf.

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 and materials handling equipment.
