Torque Limiter Mechanisms with Couplings Operation Mechanically adjustable, continuously engaged friction torque limiter slips in the event of an overload Torque at which limiter will slip is field adjustable through the tightening or loosening of a nut Adjustment nut is locked in place by set screws when desired torque setting is established Mounting Set screws and customer supplied key connect the torque limiter mechanism to one shaft and the coupling hub to a second fully supported shaft Shafts must be accurately aligned to prevent premature failure of the torque limiter Note: Torque Limiter Mechanism DOES NOT support Coupling Applications Momentary overload protection Torque limiters are not recommended in continuous slip or tension control applications. A SensiFlex® clutch or brake should be used instead. Maximum RPM varies by model. Please consult the detail sheets (below). Consult engineering if the intended application exceeds the listed maximum RPM. Design Features No reset required after torque limiter slips Both torque limiter mechanism and coupling bored to suit up to the maximum shown (US & Metric) to accept differing shaft sizes

Additional Information

Mach III torque limiter mechanisms with couplings are solidly constructed to provide reliable power transmission. Torque limiter models can be adapted to accommodate customer needs. See our Custom Design Solutions page for more information. Mach III encourages contact with our engineering department before purchasing a torque limiter mechanism with coupling for use in a new or retrofit application.
