This Range of Cast Iron Worm Gear Units have the same dimensions of the Motovario NRV/NMRV 110-130-150 sizes and can be supplied with a Motor or as a Pam type with 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- Gear casting is in Cast Iron and painted with RAL 9022 Aluminium colour epoxy power to protect against oxidation and any miro blowholes that may have been present during the Casting process!
2- As the Input Shaft seal is mounted within the casing then it is possible to fit a none IEC Motor Flange, therefore adaptable for none IEC DC & Brushless Motors!
