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.

Options for MicroCentric Chucks

UP Ultra Precision Option

 N/A

Repeating accuracy to .000020" (0.0005mm) TIR

For applications which require extremely close chucking accuracy, MicroCentric will selectively fit and certify a chuck to an accuracy of .000050" (0.001mm) or .000020" (0.0005mm) depending on model.

Note that temperature variations, changes in air pressure, spindle runout, and the condition and design of top jaws will affect chuck accuracy.

BP Back Ported Option

 N/A

Air passages through the back cover provides a hole in the center of the chuck

For applications where the workpiece must be swallowed into the center of the chuck. The BP design also enables housings with part stops or parts ejectors to be mounted into the ID of the chuck.

Air is typically supplied to BP chucks through the mounting plate which can be supplied with the chuck.
