The worm shaft is manufactured from case-hardened steel, featuring a specially designed and profile-corrected gear arrangement that delivers higher efficiency, increased load carrying capacity, and precise accuracy. The worm gear is constructed from a special non-ferrous alloy with high anti-wearing properties.
A unique profile on the worm gear ensures improved gear engagement between the worm gear and worm shaft, guaranteeing enhanced accuracy, reduced wear & tear, and uniform load distribution. This advanced transmission mechanism is utilized in all standard 4th axis and 5th axis worm gear rotary tables.
