we have a gearbox with a motor mounting flange that’s separable from the housing which incorporate the essential oil seal; in this manner we avoid any threat of damaging the essential oil seal in the event of alternative of the insight flange and the O-Ring can be eliminated. All the apart covers, swinging and with ft, have O-Rings rather than traditional toned gaskets. The sizes 03-04-05 permit the rotation of your feet without disassembling them; furthermore the versions with swinging apart covers allow the lateral flanges to be installed on both sides with basic fixing screws. The worm screw includes a ZI involute profile: with this worm-wheel coupling we will get a better performance with a temperature reduction. The gearboxes and motors are painted with RAL 9022 aluminium color epoxy powder to safeguard the parts from oxidation and against micro-blowholes that may come during the pressure of die-castings. The CHPC pre-stage gears (already within the catalogue of CHM) can also be installed with this range, finding a equipment ratio up to at least one 1:300. For larger reductions can be done to have two gears jointly using a CH WORM GEARED MOTORS AND WORM GEAR UNITS proper kit
