Gripper Style Wobble Sticks

Lesker Gripper Style Wobble Sticks

The term "wobble stick" describes a manually operated device that enables motion in up to four axes (X, Y, Z, and rotation) without gears or mechanisms.

• Used to transfer samples and sample cassettes from one position to another inside a UHV chamber
• Can operate a shutter or variable orifice that has no external actuator
• Position a measuring probe or thermocouple

The magnetically coupled wobble stick series is built on a modular concept. The basic WSL series provides lateral and tilt movement through a robust hydro-formed bellows adapter and linear push-pull motion through a magnetic coupling. The WSLR series adds continuous rotation to the WSL series.

This design eliminates the need for long edge-welded bellows stacks employed with conventional wobble sticks. This reduces the risk of leaks and does not subject the device to the thrust due to vacuum resulting in smooth, free-moving operation.
