Precision Engineered Gear Cutting Parts

Gear cutting parts for fine mechanical assembly groups and precision engineering systems

The gear has been around for more than 2000 years and today remains almost completely unchanged. The technical principle has remained the same and its elegance is hard to beat with its simplicity and efficiency.

As individual components or gear units, gear wheels and gear components form an indispensable part of many machines, such as – in our case – fine mechanical assembly groups, fine mechanical systems and measuring movements.

Gear Cutting Parts

Tried and tested gear quality. Precision you can rely on.

What is essential is the precision of the production of all gear cutting parts. This is a non-negligible factor – because after all, even the smallest wheel can bring the entire machine to a standstill. We offer gear wheels and toothed segments, through to pinions, involute splines and axels.

At Engelbert Sellmaier Feinwerktechnik GmbH, you can be sure that you will receive only tried and tested quality made exclusively in Germany.

Our range of fine mechanical gear cutting parts

With our gear cutting machines from the Swiss timepiece industry, we manufacture straight serrations such as gears, gear segments, pinions, involute splines, pulleys and other gear cutting parts with diameters ranging from 1.5 mm to 64 mm and modules from 0.15 to 1.0. Post-production processing, such as rolling of bearing points to strengthen and smooth the surface, is available upon request at Sellmaier.

With this process, we can achieve accuracies of < = 0.005 mm.
Additionally, we offer gear cutting parts made of plastic which we produce with plastic injection moulding. Plastic parts with metal inserts (hybrid) are also available.
