1. Introduction
1.1 Product Description
The PPS-28 is a low profile, high-precision linear stage outfitted with a linear or
stepper motor. Miniature cross-roller bearings assure high stiffness and guiding
accuracy for loads up to 50N (horizontal orientation). The PPS-28 SMLM is
available in travel lengths of up to 102mm, and an optional linear encoder
provides submicron repeatability. High Vacuum (10-6 mbar) compatible versions
are available.
Features:
▪Stepper Motor travel ranges of 26mm, 51mm, 76mm, and 102mm
▪Linear Motor travel ranges of 26mm, 51mm, and 102mm
▪Load capacity up to 5 kg (Stepper Motor)

3. Preparing to Install the PPS-28
3.1 Installation Preparation
When mounting the stage, it is important to consider the flatness of the mounting
surface, as the stage will conform to the shape of that surface. A surface that is
not flat can adversely affect the performance and structural integrity of the
stage.
The stage is calibrated and guaranteed to be within specification at 20°C ± 5°C.
Be sure to use the stage under the following conditions:
▪Mount to a clean and flat surface which is free of debris, burrs or dings
▪An indoor atmosphere free of corrosive gases, excessive dust, and
condensation
▪Temperature range of 0-40°C
▪Relative humidity between 20-80%
▪Locate away from water, heat, and electrical noise
