Beginning with these considerations, we have a gearbox with a electric motor mounting flange that is separable from the casing which incorporate the essential oil seal; in this manner we avoid any risk of damaging the oil seal in case of substitute of the insight flange and the O-Ring can be eliminated.
All the aside covers, swinging and with feet, have O-Rings 
rather than traditional flat gaskets.
The sizes 03-04-05 permit the rotation of your toes without disassembling them; furthermore the variations with swinging aside 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 will get a much better performance with a temperature worm gear unit 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 during 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 larger reductions can be done to have two gears jointly using an appropriate kit
