Mechanical Friction Torque Limiter Mechanisms with Adapters
Continuously Engaged, Momentary Overload Protection
Function: Overload Protection
Drive Arrangement: Shaft to Adapter Mounted Component
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
- Through/Mid Shaft or End of Shaft.
- 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
- Momentary overload protection.
- 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.
Design Features
- No reset required.
- Bored to suit up to the maximum shown (US & Metric) for easy installation.
- Machined face and bolt circle on adapter facilitate connection to bearing mounted pulley or gear.
Customization Options
All Mach III products can be customized to meet the needs of your application.
