we’ve a gearbox with a motor mounting flange that’s separable from the housing which incorporate the oil seal; in this way we avoid any threat of damaging the essential oil seal in case of alternative of the insight flange and the O-Ring can be eliminated. All the aside covers, swinging and with foot, have O-Rings instead of CH WORM GEARED MOTORS AND WORM GEAR UNITS traditional toned gaskets. The sizes 03-04-05 allow the rotation of your feet without disassembling them; furthermore the versions with swinging apart covers permit the lateral flanges to end up being fitted on both sides with basic fixing screws. The worm screw includes a ZI involute profile: with this worm-wheel coupling we shall get a better overall performance with a temperature reduction. The gearboxes and motors are painted with RAL 9022 aluminium colour epoxy powder to safeguard 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 installed with this range, finding a gear ratio up to 1 1:300. For larger reductions is possible to have two gears collectively using an appropriate kit
