<strong>Linear</strong> translator shifts are heavy duty translators<br />
designed to move large objects accurately in and<br />
out of a vacuum system. Three sizes of bellows<br />
and a variety of Z stroke lengths are available.<br />
The unit is intended primarily for vertical operation<br />
with the load supported load on the Z axis.<br />
The <strong>VG</strong> <strong>Scienta</strong> technical department should be<br />
consulted for alternative orientations.<br />

<strong>Linear</strong> Translator Shift - LTS Series<br />
The Z motion is provided through three equispaced<br />
lead screws which are synchronously<br />
driven by a drive chain. Manual operation is<br />
provided by a nut attached to the chain tensioner,<br />
or alternatively by an optional handwheel<br />
assembly operating through a wormdrive reduction<br />
system.<br />
The lead screws are firmly mounted to the fixed<br />
base flange to provide cantilever and strut support<br />
as well as providing Z motion. All translators<br />
have additional stainless steel precision<br />
guide rods running in bronze bushings.<br />
