Our standard Model 450, 650 and 800 (3-jaw) Air Chucks with .0001 T.I.R. repeatability with a self-contained actuating cylinder now offers even more. The chuck is energized with air pressure via a quick connect fitting. This Pressure-Lok™ air chuck is charged with air by a special handle and holds air pressure for over 2 weeks.These chucks can be mounted to rotary tables with no thru-hole, tombstones, pallets, transfer systems, etc. The Pressure-Lok™ air chuck is useful in any machining operation that does not have access to a continuous air supply. Unlike spring clamping, the chuck's grip force is infinitely adjustable by adjusting the air pressure from 5 - 80 PSI. The chucks were tested and held pressure with no drop for 3 weeks. All of Northfield's chucks can be adapted with this system.
