Mechanical Friction Torque Limiter Mechanisms with Adapters - Mach III

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.

Torque Limiter slides on shaft and is fixed with set screws and customer supplied key.
Adapter connects to a fully supported, bearing mounted pulley, gear, or sprocket.
Note: Mechanism DOES NOT support Adapter.

Applications

For continuous slip or tension control applications, a SensiFlex® clutch or brake should be used.
Maximum RPM varies by model. Please consult the detail sheets (below). Consult engineering if the intended application exceeds the listed maximum RPM.
