Beginning with these considerations, we’ve a gearbox with a engine mounting flange that’s separable from the housing which incorporate the oil seal; in this way we avoid any risk of damaging the oil seal in the event of alternative of the insight flange and the O-Ring can be eliminated.
All the apart covers, worm gear unit swinging and with foot, have O-Rings rather than traditional flat gaskets.
The sizes 03-04-05 permit the rotation of your feet without disassembling them; furthermore the versions with swinging aside covers allow the lateral flanges to become fitted 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 colour 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 within the catalogue 
of CHM) can also be mounted with this range, obtaining a gear ratio up to 1 1:300. For bigger reductions can be done to possess two gears collectively using an appropriate kit
