IF IT’S ABOUT PRECISION…

mg technical ceramics stands for competence and quality – look and see! For more than 20 years we have been working with national and international ball manufacturers focusing on consulting and sales with particular regard to balls and ball bearings made from ceramics and different special materials.

If highest quality, competence and innovation are the items that count you should contact us. We advise and (accompany) WORK WITH you from product choice until project finish.

We are please

to advise you in person and look forward to receiving your enquiries.
