The trend in industry is to design and incorporate more automa­tion into production processes. Machines are becoming more accurate, requiring a higher degree of precision. They are becoming faster, using servo and DC drive technology, and they are more rigid to withstand the dynamic loads necessary to increase capacity and productivity.

Torque overloads caused by material jams, operator error, or a whole host of unforeseen reasons pose a significant threat to

machine downtime.

Machine downtime in an automated production environment is very costly. Broken components, expensive technicians, and long lead times for custom components can make the difference bet­ween operating profitably or not. Torque overload couplings are an inexpensive insurance against downtime.

This catalog contains many different torque overload coupling designs. They all incorporate the patented R+W design principle. The couplings are all torsionally rigid with absolute

zero backlash.

The use of a patented R+W Torque Limiter will isolate the driving from the driven elements within a matter of milliseconds, once the torque reaches a preset overload value. Incorporating R+W Torque limiting couplings into modern machine design will help insure high productivity and higher profits.
