Sealed Air Chucks

Sealed air chucks feature a stainless steel cover that seals the jaw slides. This design prevents contamination from grit and swarf and minimizes chuck maintenance for high volume production operations. Sealed air chucks are available in rotating and stationary configurations and are ideal for cylindrical grinding operations as well as machining abrasive materials such as powdered metal, ceramic, or carbide.

QC precision located top jaw system is standard on sealed air chucks.

Chuck Accuracy

.00005" (0.0012mm) TIR is standard
