We don’t just manufacture new products. We modify and improve existing gear assemblies. Amendments to gear tooth geometry and careful material selection increase flank durability and root strength service factors, while ensuring fitment compatibility with your original gear unit or set.

All calculations are aligned with the latest American Gear Manufacturers Association (AGMA) calculation standards and are subjected to finite element analysis to identify potential stress areas. The latest in gear calculation software, including KISSsoft and Inventor modelling, are essential tools in our design process.


World-class gear grinding technology

Our state-of-the-art gear grinding technology enables us to supply gears of the highest quality. Precision gear components and pinions are manufactured to standards.

Features & Benefits

Girth Gears


In our manufacturing process, precision and quality are paramount. We employ a vacuum degassing furnace as a crucial step before casting ingots, ensuring that the resulting forgings exhibit superior mechanical properties. Additionally, our commitment to excellence is reflected in our gear grinding operations, which adhere to a minimum accuracy standard of AGMA Q12 class or higher. This meticulous approach guarantees the production of high-quality components with precise specifications, meeting the stringent standards required for optimal performance in various applications.
