Product Description

We are professional Integral Self Reversing Screws factory from china
The material is ASTM 4140 and HB 240-270 or according to the customer's individual specification.

The length is less than 5000mm and the diameter is less than 300mm.

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 customer. Besides the standard pitches we can also process many non-standard pitches to meet the design requirements.

The surface of our spooling shaft can be finished by two methods. The surface can be grinded by a grinding machine and the surface is smoothed. The surface can also be rolled by a special tool and the surface is smoothed and also hardened.
Please send us the drawing of Integral Self Reversing Screw that you need, we are glad to quote the best price for your side
