4.5" CF Long Travel Linear Shifts

4.5" CF Long Travel Linear Shifts

The Kurt J. Lesker LSML is the long travel series of UHV linear Z shifts, providing strokes of up to 1m (39"). The series incorporates an upgraded structure, to maintain performance throughout their stroke. LSMLs can also be selected for shorter strokes, where ultimate stability is required.

The LSML is the most sophisticated product in the range offering a complete solution to linear motion, with numerous "plug-and-play" features.

Linear transfer mechanisms are UHV clear-bore bellows assemblies in which the top flange moves toward or away from the bottom flange, maintaining parallelism.

• Rugged design ensures smooth and precise motion along the Z-Axis
• Support high loads, but the actuator should be carefully chosen to suit the physical effort and precision required for positioning
• Flange options: 2-3/4" or 4-1/2"CF with straddled bolt-hole orientation, metric tapped holes as standard
• Demountable bellows assembly
• Precision stainless steel ACME leadscrew
• Precision-ground stainless steel guide system

Features

• Designed for the linear movement of large flange-mounted instruments with minimum tilt or wobble in the movement, and allowing precision alignment before and after pump-down
• Manual units operated handwheel drives
• Motorized units driven by stepper motor or DC motor mechanisms
• Drives support bellows assemblies in a precision kinematic guide system, complete with anti-rotation and anti-deflection systems
• Standard travel distances of 200mm through 1000mm (custom units available)
• Ideal for manipulation of surface science tools with respect to a sample's position, manipulation of evaporation and sputter sources, substrate and source shutters, sample heating stage adjustment, sample transfer applications, and general sample manipulation
