Martin SPH-31, Shear Pin Hub

Description

Martin SPH-31, Shear Pin Hub
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.

The new ebay buyer protection program has inspired us to offer all of our items “as-is”.
This does not mean that you are buying a machine with deficiencies, known or unknown.
What it means is that some of our items will be tested and will include the results in the description and others will be untested but described accurately to the extent that is possible without actually powering up the machine.
In addition to this written description you will have the opportunity to view high quality photos of the item.
With these two sources of information you will have as much information as possible without being physically here to inspect the machine.
Feel assured that we will make a diligent effort to give you an accurate description of the equipment.
As a buyer you should be aware that you are buying an expensive piece of equipment at a greatly reduced price and as such you may have to deal with certain unknowns and defective components which were not known and could not be known without full scale setup and operation of the machine.
Our experience in dealing with many specialized pieces of equipment has proven this to be a rare occurrence however it is a risk inherent in buying used equipment.
The very few times we have had to deal with these issues we have been very helpful in resolving the problem.
