Like all motion control devices based on contact friction, ball screws require lubrication for proper functionality. The reason is that lubrication is required for smooth recirculation of the rolling elements.
Customers often ask us: what type of lubricant is best for my ball screw application? And which is better, oil or grease? The truth is that both oil and grease can perform well in a variety of situations.
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:
Hah – got your interest with that title, right? But is there really such as component as a ball screw that requires zero maintenance? First we should establish exactly what we mean by “zero” maintenance. This can be one of two scenarios: either the ball screw has absolutely no lubrication, that is it runs dry; or the ball nut includes enough lubricant and is sufficiently protected such that no further maintenance is required for its lifetime. BTW for either scenario the answer is pretty much “NO, it’s not possible!” Continue reading
A question that often comes up for miniature ball screws – how do I lubricate it if there is no port on the ball nut? Good question! If you check our web site there is quite a lot of detailed information on lubricant types and wiper types, including precise amounts to use when re-lubricating:
There is certainly a wealth of information on lubrication on our web site – here is a link to the main page regarding oils and greases: http://www.steinmeyer.com/en/technology/drive-technology/lubrication-and-wipers/
There are however two issues that should be emphasized: Continue reading
