Used for installing switching mechanisms on railway lines, the drill press to which this torque limiting coupling is attached sinks large screws into railroad ties made of various materials such as steel, concrete, plastic and wood. Each material requires a different size of screw and a different amount of drive torque. The railroad workers are able to manually adjust the slip torque setting of the coupling to the value needed for each material by loosening or tightening the adjustment nut. The output shaft allows for the quick interchange of sockets to accommodate the various screw sizes.
Mach III provides rapid turn-around for application adapted designs. This torque limiter was designed and quoted within 24 hours of the initial discussion between the client and our engineers. The units were manufactured within 3 weeks.

Commonly used to open and close gate valves in water treatment and irrigation systems, this friction torque limiter coupling connects to a power drill with a #3 Morse taper socket. A variety of output options are available including different sized squares and keyed bores. The coupling is pre-set at the factory to a torque value you specify and may be adjusted in the field if needed. When the torque setting is exceeded, the coupling slips to prevent over tightening.
