This New & Improved Design of Worm Gear Units have the same dimensions of the Bonfigiloli W63-75-86 sizes and can be supplied complete with a motor or as a Pam type with a Hollow Input shaft and motor Flange, hence dimensional replaceable and therefore no need for redesign or drawing changes, but offering the following improved design features:
1- A Seperate Motor Mounting Flange that does not include the Oil Seal so as to avoid any seal damage when replacing the Motor Flange eliminating the need for the O Ring!
2- The Worm has a ZI involute profile to improve performace and reduce Temperature!
3- Gear castings are in Aluminium and painted with RAL 9022 Aluminium colour epoxy power to protect against oxidation and any miro blowholes that may have been present during the pressure die-casting process!

Lubrication:
All CH Series sizes are pre-filled with Synthetic Lubricant to ISO VG320 -25C/+50C and are maintenance free with sufficent lubricant for mounting in any position!.
Tips:
Non Standard Input Flanges:
As the Input shaft seal is now mounted in the gear casing rather than the Input Flange, then it is now possible to fit none IEC Motor Flanges as required for DC or Brushless Motors?
