MS-Graessner Gears: Gearing precision with performance.

PowerGear Miniature

PowerGear MiniatureNEW Icon

The Revolution among Miniature Gears.
Forget everything you know about miniature gears. Dimensions, weight, precision – the new PowerGear Miniature sets new standards. PowerGear Miniature has a sensationally small installation size, an extremely light-weight aluminium housing, maximum performance and precision as well as many other advantages. The unique design of PowerGear Miniature will open up a vast range of applications in drive technology.


MS-Graessner – Engineering

We realize any gear.
Nearly any.

For everyone who expects more: special gearboxes from the specialist

Our engineering and special manufacturing techniques have helped us become precision manufacturer of tooth systems and bevel gearboxes for almost 60 years, as well as specialist in special gearboxes.
For us, individual solutions are standard. And instead of offering expertise that‘s confined to certain areas, like pure development for instance, we offer comprehensive know-how in all relevant areas – from the specifications and the first sketch up to the manufacturing of the zero series including intensive test operations.
Our expertise also extends to a special in-house developed workflow management system: for optimal processes between all areas involved and the customer. Our quality management system thus guarantees highest quality and cost certainty.

We use modern software tools – GEARFOX – KISSsoft – Gleason – and own software solutions.
