The Rotary Pincer Wobble Stick Multi-Motion Feedthrough is a high-precision manual actuator offering full rotary, linear, and angular motion combined with an integrated pincer mechanism. Built with a ball-and-socket joint shaft design, it provides 360° continuous rotation, 4-1/2 inch (114.3 mm) of linear travel, and 22° of angular wobble. The pincer jaws, operated by shaft-mounted finger grips, securely hold samples up to 0.880 inch (22.35 mm) in diameter. Designed for real-time operation through vacuum viewports, this device includes independent linear and angular position locks for secure manipulation. Constructed from UHV- and HV-compatible stainless steel and sealed with welded bellows, it mounts via 2-3/4 inch (69.85 mm) Conflat® CF or ISO KF Kwik-Flange™ ports.

Industry Applications

This rotary pincer wobble stick is ideal for precise sample manipulation, component placement, and in-situ inspection in vacuum systems. Commonly used in surface science, semiconductor R&D, materials analysis, and vacuum assembly, it enables three-axis manual control with grip functionality in UHV and HV environments.
