TEDISA is a company that manufactures hirth crown gears. Founded in 1988, our company has become a world leader thanks to the precision of its hirth serrations (+1" division precision), and to its strict compliance of delivery times.
We have a large stock of Standard crown gears, whose measurements can be consulted in our "Standard Series" section.
We also make sets of crown gears, in two and three parts, to the customer’s plans, up to a maximum diameter of 1500 mm. Our facilities are over 3500 m², fitted with the latest production and verification resources on the market.
As a complement to our hirth crown gears, TEDISA also produces rectifiers up to 2000 mm in diameter, used to rectify parts with great precision.
