Haydon Kerk G4 36 mm linear actuator

The Haydon Kerk G4 36 mm linear actuator is claimed to have a 20% higher output force that allows the 36 mm to replace larger 42 and 46 mm units. It includes a special adaptor plate to allow ‘drop-in’ replacement of larger units.

More power in a smaller physical package is of great benefit where space is critical and the 36 mm unit offers a price advantage of the larger units. When replacing a larger unit, the adaptor plate allows the G4 to be mounted using the same bolt pattern, which simplifies installation of the upgrade.

Force output for the G4 is from 70 to 260 N and the unit is available in three configurations: captive, where the screw is held from rotation by the actuator; non-captive, where the screw drives through the motor; and external linear, where the motor drives the screw with the load nut running externally on the screw.
