Automation 4 Less


Automation 4 Less has now broadened its selection of ball screws to include private-label PRECISION ROLLED PRODUCTS from a trusted source. The hallmark of this line is its lower cost (compared to ground screws) while still retaining accuracy levels (C7) that meet or exceed the requirements of most applications.

We are stocking a wide range of lengths of these assemblies in 16mm ø, 20mm ø, 25mm ø and 32mm ø (with your choice of 5mm and 10mm lead). All assemblies come with ends already machined for the economical BK/BF or FK/FF mounts that we also supply. We also offer many other accessory items. Our commitment to a stocking program means you can order products today and have them in your hands tomorrow (if you need them that fast).
