Eichenberger thread drives Standard range overview Thread drive types and their characteristics Cold-rolled precision The manufacturing core competency of Eichenberger Gewinde AG is thread rolling. That is why the thread profiles of Eichen- Eichenberger ballscrews are characterised by: Eichenberger leadscrews are characterised by: berger screws are exclusively made using this highly precise process. Thread rolling describes the cold-forming process of the surface load ratings, and are therefore suitable for high static of round components. A thread is created by deforming a part between two...

Eichenberger ballscrews Assembling of ballscrew units Production lengths In general, Eichenberger screws are produced as threaded rods Ballscrews are precision parts and must be protected from shock, Production / Handling / Lubrication dirt or moisture when transported or stored. Please do not unpack until ready for use. Please check for cleanness when mounting the ballscrew. Dirt or foreign matter on the ball race – especially inside the nut – may Ballscrew ends are without any machining cut by grinding cause increased wear and premature failure. Remove transport lock (O-ring) on one side....
