TRACTION DRIVE
The worm shafts of our gears are cut from case hardened forgings of alloy steel. These hardened worms are ground and polished to provide perfect tooth profile and maximum smoothness of surface, thus, minimizing friction, conserving power and reducing wear. The rims of the worm wheel are made from centrifugal cast bronze, machined to mate precisely with the worm.
Through centrifugal casting we are able to obtain fine and perfect homogeneity of material structure with great fracture resistance and excellent sliding properties. Similarly, all our equipments are manufactured to exacting standards and precise tolerances. We use the finest  materials which are cut on the most modern machines.
