This unit is essential in order to operate MK4 Self-Contained Power Chucks. It is designed to be interlocked with the machine spindle so that the chuck cannot be actuated while the spindle is under power. Care must be taken not to actuate the chuck while the spindle is decelerating.

Units are supplied complete with pressure gage, pressure regulator, oil mist lubricator, air filter and lines with fittings.

Unit is operated by air and 110 volt/60 cycle (24 volt DC on request).
