A Pneumatic Stationary Expanding Collet Chuck is a non-rotating, air-operated internal workholding system that clamps components from the inside diameter with dead-length accuracy. It ensures zero axial movement, excellent concentricity, and distortion-free holding, making it ideal for thin-wall rings, sleeves, bushes, and bearing housings in CNC lathes, SPMs, transfer lines, and automated production cells.
Product Overview
Pneumatic Stationary Expanding Collet Chuck is a non-rotating, air-operated internal clamping system that grips components from the inside diameter (ID). Its dead-length design ensures no axial movement during clamping, delivering consistent length control, excellent concentricity, and distortion-free holding—ideal for thin-wall rings, sleeves, bushes, and bearing housings.
Designed for CNC lathes, SPMs, transfer lines, and automation cells, this chuck provides fast pneumatic actuation, high repeatability, and long service life.
