Mastergear “M” series worm gear actuators

The cast iron construction and rugged design of the Mastergear ‘M’ series manual valve actuators has been engineered to meet the arduous requirements demanded of industrial environments. Through corrosion resistant treatment of bare metal surfaces, a grey epoxy paint finish and the use of lip seals with multiple sealing surfaces, the ‘M’ range is sealed to IP 67 and achieves exceptional durability.
Models M07 to M 16 use high performance axial needle roller bearings, which combined with a one piece input wormshaft, maximises the available mechanical advantage and overall unit efficiency. Mastergear now have an “M” series for virtually all applications, the all new M60 is rated to a maximum torque capacity of 113,000Nm.
