LMC Workholding offers the Energy series large-bore air chucks, featuring a built-in air cylinder and extra-large through-hole. The full spindle bore of the lathe can be utilized for through-hole work and long jaw travels provides more clearance for through feeding pipe. These large pneumatic chucks are available in standard and extended jaw-stroke models.

Other features include self-contained construction that allows these chucks to be installed on the front and back of the lathe spindle for producing high quality threads. Extended jaw stroke for processing pipe with upset ends and extended jaw travel features both a rapid and a clamping stroke. External or internal clamping of the workpiece is also possible.
