Reversing Screws and Housing Assemblies

We have been the leader in manufacturing reversing screw assemblies for over 40 years. Reversing screw assemblies create a continuous uniform linear motion in two directions without changing the rotational direction of the shaft. To eliminate the high cost and long production time, Wedin International developed design standards that allow us to provide a simple, economical and functional product. With over 1500 variations of reversing screws, Wedin International is able to provide you with a fast and efficient replacement solution for your ball screw products. If our stock of reversing screws does not meet your requirements, our knowledgeable and skilled team can manufacture them to your specifications.

  • Stock sizes ¾ inch to 2 inches in diameter Custom sizes from 2” to 6” diameter
  • Length can be adjusted to customer specifications

In-Stock Acme Screws and Nuts

At Wedin International, we understand the need for fast turnaround time, which is why we keep a selection of our Acme screws along with standard and adjustable style Acme nuts in stock at all times. These assemblies are designed to be machined to customer requirements, if necessary, to custom mounting requirements. Our stock Acme screws are manufactured from “stress proof” steel, a material that is easily machinable, stable, and has good longevity characteristics.

Wedin has introduced a stock adjustable nut assembly for application where control of backlash is essential for precision movements. Available in both “Pillow Block” and “Flange” mountings our adjustable nut assemblies are pre-set when they are shipped. Our adjustable nut design has been quality tested and provides optimum wear and accuracy for the life of the assembly, giving our customers a large value on the return on their investment in ball screw products.
