Worm wheel sets 16 / GFC Product Catalog 2012 Design properties of GFC worm wheel sets: >> worm shaft made of 16MnCrS5, case-hardened and ground >> splining according to DIN 3976, clockwise-ascending, (quality according to DIN 3974: worm shaft 6, worm wheel 7, others by request) For non-run-in worm shafts and worm wheels of the same type, we warrant full exchangeability. The only exceptions to this rule are worm wheel sets with a narrowed backlash. Such wheel sets are adjusted to the actual dimension of the housing-centre-point- distance and labeled in pairs. Dimension sheets Size 40 – 80 Requirements for the flawless function of GFC worm wheel sets: >> correct tooth-bearing setting >> corresponding storage >> sufficient lubrication >> running-in has already been performed The worm sets are operable in both rotation directions. Please enquire as to wheel sets with counterclockwise-ascending splining and custom splining.
