What is Ball Screw?
Ball screws assemblies offer an efficient means of converting rotary motion to linear motion. A ball screw is an improvement over an acme screw just as an antifriction ball bearing is an improvement over a plain bushing. Precision ball screws have a number of bearing balls that transfer the load between the nut and screw. The thread form in which the bearing balls ride is an ogival shape formed from two arcs of the same radius with offset centers. This form is also referred to as a gothic arch.
Minor wear condition can be corrected properly by reloading the nut & screw with over-sized balls. Choosing between rebuilding or replacing can often be a difficult decision for you to make & we are here to make that decision easy.
Ball Screw Reload
The ball screw is cleaned and completely inspected. Bearing journals are inspected for proper size and critical runout and concentricity to the screw diameter. Worn bearings need to be corrected for the ball screw to function properly.
Rebuilding Ball Screws
Our rebuilt ball screws will look and perform as well as a new one. We have developed a successful repair process that sets us apart from our competition. This allows us to offer our customers the best value and unbeatable turn around time.
