Beginning with these considerations, we've a gearbox with a motor mounting flange that is separable from the housing which incorporate the oil seal; in this manner we avoid any threat of damaging the essential oil seal in case of 
All the aside covers, swinging and with foot, 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 apart covers permit the lateral flanges to be fitted on both sides with basic fixing screws.
The worm screw has a ZI involute profile: with this worm-wheel coupling we shall get a much worm gear unit 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 present in the catalogue of CHM) can also be mounted with this range, obtaining a gear ratio up to 1 1:300. For bigger reductions is possible to have two gears jointly using a proper kit
