Overview
The Browning 187764 TP20X3/4 is a Torq/Pro ball detent overload clutch engineered to protect machinery from jamming and overload conditions. This release-type torque limiter features a single-position reset configuration, allowing automatic reset when the drive is cycled back to the set position after an overload is cleared. Ideal for conveyor drives, machine tools, and transmission shafts, it delivers consistent torque control with an accuracy of ±10% even after repeated tripping.
Key Features
- Ball Detent Design: Asymmetrical ball detent pocket pattern ensures engagement in only one position, eliminating confusion during setup and operation.
- Automatic Reset: Single-position reset mechanism automatically resets when the driving member rotates back; typically engaged by jogging the machine after overload is cleared.
- Precision Torque Accuracy: Trip torque remains within ±10% throughout the life of the unit, even with repeated tripping cycles.
- Adjustable Torque Range: Torque capacity easily set and adjusted by tightening or loosening adjusting nuts and bolts; visual torque meter and indicator confirm setting.
- Straight Bore Configuration: 3/4″ diameter bore with 3-1/2″ outside diameter and 1.85″ overall length fits standard shaft applications.
