REQUEST MORE INFO

This is an unused Martin SPH-31 shear pin hub. Shear pin sprockets provide simple, dependable protection against expensive machinery damage caused by overloads or jamming. Torque is transmitted by a single pin, necked to shear when the safe load is exceeded. When an overload occurs, the pin shears, disconnecting the drive immediately. This must be used with Martin SPA-31 to be mounted on a sprocket. Includes 3 shear pins.

This was removed from a large sprocket. Despite being removed, it was never mounted on machinery.
