Ball screws (Precision)

Ball screws that have been cold rolled formed are ideal for applications that do not require the finite accuracy of the ground ball screw equivalents, but are still required to reliably transmit a linear load with high degree of accuracy.

Put simply, the rolling process forms a thread for less cost than grinding. However, we can still achieve accuracies of C7-20 (that's 52 microns per 300mm of lead accuracy - 20 microns of axial backlash) .

Standard thrust bearing machining detail

A complete end machining capability is available to you. Lets work together to reduce your scrap rates and supply the lead screw solutions that fit your application every time. We can work directly from your dimensional drawings or if they do not exist, why not supply us with a physical sample for us to copy.

 

Thrust and radial bearings to suit precision ball screws

Please do not forget to ask for our competitive support bearing prices !

 

Linear guides and rails

If you are interested in the using  ball screws, please do not forget that we also supply the full range of linear guides and rails which can provide the load support in your linear mechanism. Offering excellent rigidity and parallelism during operation the guides can be used in both vertical and horizontal planes.
