Winch diamond screw is an important part of winch spooling device. It can ensure to wind the wire rope onto the winch drum correct and evenly. That can Improve winch technology level and extend the wire rope life.
There is not a standard range for this shaft type. They are designed and manufactured to meet the customer's individual specification.
The material is ASTM 4140 and HB 240-270 or according to the customer's individual specification.
We suggest clients to select diameter, length and pitch of spooling shaft according to below list (unit mm)

We are specialized in the spooling technology of winches. We know winch spooling device operation rule and design key. If the customer provides the distance between two flanges of winch drum and the diameter of rope and the diameter of spooling shaft to us, we can design the pawl travel distance, pitch, turns, under-cut, drive ratio of chain transmission for the customers.
Besides the selectable pitches in the list we can also process many more special pitches to meet the design requirements.
We have manufactured many winch self reversing screw shafts and spooling nuts for our clients. Our customers are mainly distributed in eastern Europe, Western Europe, Southeast Asia, and Oceania, etc.
