The Alternative in Linear Technology
Rolled ball screws from Steinmeyer are in most of the cases a highly attractive alternative compared with other driving solutions, like rack and pinion or belt-drive systems.
Steinmeyer rolled ball screws are used in linear modules in handling applications, in medical applications, and also on the feed axis in woodworking machining centers.Through a highly efficient and fully automated deformation process in the manufacturing of the screw shafts, Steinmeyer rolled ball screws exhibit a very attractive price-to-performance ratio, along with high precision. This product is available as a ready-made ball screw, with the nut mounted and bearing journal machined, or delivered as an unmounted shaft and nut.
The hardened and tempered screw shafts can be produced in lengths up to 3m, for nominal diameters of 20mm or below, and up to 6m in diameters of 25mm and above.
Steinmeyer rolled ball screws are executed in an accuracy class up to T5, looking at the lead error and also at all other specified tolerances in geometry and position.
Using either a liner or an axial deflector system, the single nuts are designed with a flange according to ISO 3408 dimensions or with a connecting thread.![[Translate to English:] Kontakt](/fileadmin/media/steinmeyer/kontakt.jpg)
