The HLSML provides strokes of up to 1000mm (39") with high precision motion maintained throughout the stroke. The HLSML is also chosen for shorter strokes where ultimate stability is required.
- Up to 1m stroke
- Smooth kinematic motion
- Reliable and rigid construction
- 'Plug and play' production solutions
- True UHV performance
- Bakeable to 250°C
- Demountable bellows
The HLSML series of long travel Linear Shift Mechanisms, incorporates an upgraded structure with rear spine and large bore shafts and supports. The rigid structure maintains precise motion and unrivalled stability with strokes up to 1m.
High duty cycle production HLSMLs are available providing reliable, smooth and rigid motion with long operational life. Production ready HLSMLs can be supplied with pre-wired switches and connectors for 'plug & play' operation.

The series can be actuated via a manual handwheel, DC motor or stepper motor.
Motorised HLSMLs are fitted with bakeable limit and home switches, pre-wired to a single, bakeable connector mounted on the frame. HLSMLs are compatible with UHV Design's SADC and Stepper motor controller range.
Each HLSML can be supplied with a digital linear scale, offering visual position indication with 10 micron resolution.
|H||Manual||A manual handwheel provides the most basic method of actuation.|
|SD||DC Motorized||A 24V DC motor provides the motion and is mounted to the side of the LSM.|
|SADC||DC Motorized||A 24V DC motor side-mounted with controller and pre-wired switches.|
|SS||Stepper Motor Driven||A stepper motor provides the motion and is mounted to the side of the LSM.|
Position Readout/Feedback Options
|ES||Engraved Shaft||Linear Shift Mechanisms can be fitted with a scale with 1mm increments for visual positioning.|
|DLA||Digital Linear Scale||Digital scale displays are fitted to Linear Shift Mechanisms via a kinematic mount ensuring precise and repeatable location, which is critical for accurate repositioning after bakeout. The scale features large, easy to read characters that can be switched between metric and imperial units. The readout has a resolution of 10 microns (0.01mm). Users can set the ‘Origin’ at any position of its stroke, from which it will provide a plus/minus scale in the units selected. The ‘Origin’ is retained in its memory until re-set by the user, even when switched off. A second temporary ‘Zero’ facility is offered to enable one-off measurements to take place, which resets to the ‘Origin’ setting when turned off.|
|EN||Linear Encoder||The linear encoder (EN) option is selected where position feedback of the Linear Shift Mechanism traveling flange is required for closed-loop control applications. The EN is a contactless high-speed linear magnetic encoder which features a compact sealed read head providing resolution of 10 microns. Designed for extreme environments, the EN can be interfaced to a number of analog devices such as a PLC or motor controller. The EN is attached to the LSM frame with a kinematic mount enabling it to be removed if bakeout is required.|
