we've a gearbox with a motor mounting flange that is separable from the housing which incorporate the oil seal; in this way we avoid any threat of damaging the oil seal in the event of alternative of the insight flange and the O-Ring could be eliminated. All the apart covers, swinging and with foot, have O-Rings instead of CH WORM GEARED MOTORS AND WORM GEAR UNITS traditional smooth gaskets. The sizes 03-04-05 permit the rotation of your feet without disassembling them; furthermore the variations with swinging aside covers allow the lateral flanges to end up being installed on both sides with simple repairing screws. The worm 
screw includes a ZI involute profile: with this worm-wheel coupling we shall get a better functionality with a temperature decrease. The gearboxes and motors are painted with RAL 9022 aluminium colour epoxy powder to protect the parts from oxidation and against micro-blowholes that can come during the pressure of die-castings. The CHPC pre-stage gears (already present in the catalogue of CHM) can also be mounted with this range, finding a gear ratio up to 1 1:300. For larger reductions is possible to have two gears with each other using a proper kit
