Manufactured from induction-hardened and ground 42CrMo4 steel, they offer superior precision and strength. Their modular design allows for various tooth configurations (internal, external, or toothless according to DIN 3967), specific sealing systems, and diverse mounting options.
Tecma Drive’s comprehensive manufacturing: Design, machining and thorough internal control, guaranteeing reliable and durable solutions for advanced engineering.
