Level winder screws are often used in offshore industries to spool heavy cables on winches. A self-reversing screw then guides the cables evenly from flange to flange. The harsh conditions offshore – the constant contact with salt water and extreme weather fluctuations – pose a particular challenge. Optimum precision and the very best quality can literally save lives.
We manufacture self-reversing screws out of various materials such as 1.4057, 1.4301, 1.4404, 1.4418, 1.4571, 1.7225, 34CrNiMo6V but also Inconell and Titanium for special equipment in polar and marine research, where intergranular corrosion must be excluded in extreme depths.
Apart from large off-shore winches a self-reversing screw can also be used as a level winder screw for winding up ropes in crane construction or for spooling yarns in textile production.
Self-reversing Screws / Diamond Screws
We manufacture custom-made diamond screws or self-reversing screws based on your drawing or sample. Self reversing screws are often referred to as level winder screws, reverse spooling screws or diamond screws. They are used in hoisting winches in spooling equipment known as level winders for neatly winding layer upon layer of extremely heavy cables that are often thousands of meters long.
Whether extra-large or super-small, we manufacture self reversing screws or diamond screws according to your individual requirements based on your technical drawings – even in non-standard sizes.
