O-Ring_Connected_Torque CouplingUsed 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.
