SDS Low-Profile, Single-Row Ball Bearing Stainless Steel Linear Stages

SDS Series linear translation stages feature the lowest profile while supporting single- and multi-axis linear travel of moderate load capacities on a specialized groove profile for the stainless steel ball-bearings. Designed with industrial OEM systems in mind, the stainless steel body provides sturdy motion and long-term stability using a minimal number of machined parts.

Exceptionally low profile
Side mounted actuators for an even smaller footprint
Ball-bearings and optimized gothic arch contact profile
Smooth and rigid travel with <150 µrad angular deviation
Non-influencing locking mechanism

Features

Sturdy Travel for Moderate Loads

Our novel manufacturing methods, based on fewer machined parts, allows for a low-profile design with higher performance for moderate load capacities up to 36 lbs. (160 N). They can be stacked into multi-axis configurations with 90° angle brackets available for vertical motion. (To mount M-SDS25 and SDS40 stages to optical tables having 1 in. (25 mm) or larger grid, Slotted Bases are needed and sold separately.)

Optimized Bearing Contact Profile for Smooth Travel

Compared to classic single-row ball bearing V-groove profile, SDS stages feature unique bearing way profile which provides extended contact with the stainless steel ball bearings to achieve improved stiffness, higher load capacity and optimized stress distribution at the end of the contacts.

Side Mounted Actuators for Minimum Footprint

Side-mounted micrometers minimizes the overall stage footprint while maintaining a low profile. These stages also feature an easy access locking mechanism for each axis. SDS Stages are available in three square sizes with sides measuring 25 mm, 40 mm, and 65 mm, and are supplied with a BM Series Micrometer already installed.

Slotted Base Plates

Slotted base plates are available for versatile mounting of SDS stages to optical tables or other stages. Please see the accessory section for more information.

Multi-Axis Configurations

Two SDS stages can be easily stacked to provide XY translation. A 90 degree angle bracket can be used to build XYZ configuration. (3) SDS40 stages in XYZ assembly with SDS40-BK bracket is shown on a B-2B base plate.
