Northfield Precision Instrument Corporation offers mounting air chucks to rotary tables and pallets. Northfield’s engineering team has developed a brand-new chucking system that requires NO air tubes or hoses. This Pressure-Lok air chuck is charged with air by a special handle and holds air pressure for more than two 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 an air tube near the machine.
