In recent years, ball screws have been looked at more and more favorably as replacements for hydraulics. They offer higher efficiency and speed, and can be controlled more precisely with servo loops. And who wants to deal with the unavoidable maintenance and disposal hassle of hydraulics?

Proper functioning wipers are an essential element of any ball screw system. Their first job, of course, is to shield the contact surfaces from contamination. But some wipers may also serve as a lubricant reservoir, thereby lengthening service intervals. Fortunately, Steinmeyer offers the industry’s widest choice in wipers:
