we’ve a CH WORM GEARED MOTORS AND WORM GEAR UNITS gearbox with a motor mounting flange that’s separable from the housing which incorporate the essential oil seal; in this way we avoid any threat of damaging the oil seal in case of replacement of the insight flange and the O-Ring can be eliminated. All the aside covers, swinging and with ft, have O-Rings instead of traditional smooth gaskets. The sizes 03-04-05 allow the rotation of your feet without disassembling them; furthermore the versions with swinging aside covers permit the lateral flanges to become fitted on both sides with basic repairing screws. The worm screw has a ZI involute profile: with this worm-wheel coupling we will get a better functionality with a temperature decrease. The gearboxes and motors are painted with RAL 9022 aluminium color epoxy powder to protect the parts from oxidation and against micro-blowholes that can come through the pressure of die-castings. The CHPC pre-stage gears (already present in the catalogue of CHM) can also be installed with this range, obtaining a equipment ratio up to 1 1:300. For bigger reductions can be done to possess two gears collectively using an appropriate kit
