LDS Linear Drives

Precision UHV Linear Drives

UHV Linear Drives can be used for a range of applications requiring small distance travel such as moving electron optics nearer to a loaded sample. The LDS are our most popular range of linear drives and offer 20μm resolution and repeatability. Available in 2 conflat flange sizes, 34mm and 70mm OD. The product range utilise high quality edge-welded bellows and have a linear motion range from 25mm to 150mm which can be fully motorised with encoder and limits.
