Why Can’t I Just Buy a Shaft and nut from you Guys and Machine the Ends Myself?

At least once a week we get such an inquiry – someone looking for a ball nut and separate shaft long enough so they can cut it and machine the journals themselves, usually thinking this will significantly reduce lead time.  And of course, compared to buying a completely custom ball screw, it may just do that.  There are several reasons why we do not offer separate shafts and ball nuts, or complete ball screw assemblies with unfinished ends.  Continue reading

Steinmeyer Ball Screws and End Users

Every week we get one or more calls from companies seeking support for their Steinmeyer ball screws.  If the call is from an OEM, we bend over backwards in our attempt to support them technically as well as commercially.  However if it is from an end user it’s a bit more complicated.  Why?

What is Steinmeyer Doing to Increase Capacity?

Most ball screws are used in machine tools and related products. Virtually each year that we have been producing ball screws (45+ years!) demand has increased.  And the last 2 to 3 years it was worse than ever. Why?  Several reasons:
1. generally robust business conditions for machine builders since the 2009 recession – the rebound exceeded everyone’s predictions Continue reading

Why Does Steinmeyer Rarely Make a Ball Screw by Cutting an Existing Shaft?

Some manufacturers of ground ball screws produce long threaded shafts in quantity and then cut them down as needed to make shorter units.  This is not our normal business model.  Steinmeyer will do that on very rare occasions to save some time but only if the quantity desired is one or two pieces, and of course provided the longer shaft is available.  Why?

Why are Ball Screw Deliveries so Long?

Steinmeyer manufactures more than 250,000 ground ball screws per year – or close to 5,000 per week.  We are often asked what some may consider a pretty simple question -“how long does it take to actually manufacture a ball screw?”  The reason we think this question is not so simple is because there are several issues to consider: machining time, assembly time, inspection time, machine maintenance time and the usual culprit for delays – production scheduling.  Continue reading

Ball Screw Repair

There are millions of Steinmeyer ball screws in use today and we are often asked “does Steinmeyer offer repair services for ball screws?”  And the answer is yes, for very limited situations.  However we are aware that many ball screw users routinely get screws repaired at companies whose main business is repair – and one has to be very careful about what to expect of such a repair.

Looking for a Replacement Ball Screw in Your Machine?

Steinmeyer is a global leader in ball screw manufacturing.  Our focus is on the OEM market, which to us means anyone who makes as few as several machines per year to those that build and ship thousands.  We do not focus on machine rebuilders or end users.  We are often approached by end users seeking replacement ball screws for their machines – and our reply is often a polite “sorry, no, we cannot sell you a Steinmeyer ball screw”.  Continue reading
