Our promise to every clientOur slewing bearings keep heavy machinery turning across a wide range of sectors
A track record of steady growth since 2019, built on precision and continuous improvement.
Tecma Drive was founded by Marian Baisan and Mihaela Baisan with a small, dedicated engineering team, committed to delivering top-quality slewing rings tailored to each client's needs.
Just a year in, we earned our first ISO 9001 certification, reflecting our commitment to consistent quality across every manufacturing process.
We moved into new, modern facilities, expanding our production and storage capacity and equipping our lines with advanced testing and inspection technology.
We achieved ISO 14001 certification for environmental management, and expanded our facilities with new production lines and dedicated R&D space.
Every ring and drive we ship carries the same promise we started with: uncompromising quality, engineered around your application. The next chapter is yours to write with us.
