The Dalton ROSDC (Rigid Overload Safety Device Coupling) provides overload protection through the use of an OSD unit combined with a rigid coupling half counterbored to fit the OSD flange. All steel rigid coupling half is bolted to a basic OSD unit to form a rigid coupling with the overload feature.

The ROSDC can be set with a torque wrench for maximum load desired. The unit funcitons as a rigid coupling until an overload occurs, causing the ROSDC to disengage. The device is automatically reengaged when the overload is eliminated.

FORMULA FOR TORQUE-HORSEPOWER (Foot Pounds)

TORQUE (Foot. Pounds) = (HPx5252)/RPM
HORSEPOWER = (Torque x RPM)/5252

Important Note:
The "ROSDC" overload safety device can be made to suit your application. Send us your blueprints or specifications, for recommendations by our engineering department.
