- Integrated, low-profile, XY, ball-screw stage
- Long-life linear motion guide bearing system
- Optional low thermal expansion glass linear encoder
- Cost-effective, high-precision planar performance
Robust, High-Precision DesignThe PlanarSL comes standard with a precision-ground and preloaded ball screw. Unlike competitive designs where the ball screw is positioned on the side or off-center, the PlanarSL is designed to drive directly through the centers of friction and stiffness resulting in superior geometric performance and accuracy.
High-precision linear motion guide bearings provide excellent straightness and flatness performance while supplying optimal support of the moving carriage over the entire XY travel. Using careful design and years of experience in precision motion systems, the PlanarSL structural elements have been optimized for the highest possible planar performance.
Optional Low Thermal-Expansion Linear EncoderUnlike competitive designs using steel (13 ppm/˚C) or glass scales with 8 ppm/˚C thermal expansion coefficients, the PlanarSL is available with low-thermal expansion (3.3 ppm/˚C) precision glass scales on both axes allowing for high-accuracy and repeatable positioning over long periods of time. The linear encoder, available with amplified sine (1 Vpp) or 0.1 µm TTL digital outputs, is mounted near the centers of action, again providing an optimized stage solution for high-accuracy positioning.
Configuration OptionsThe PlanarSL is available standard with a 24 VDC bipolar stepper motor. Aerotech can also provide brushless and brush DC motors with high-resolution rotary encoders preconfigured for use with Aerotech controls.

Aerotech offers both standard and custom integration services to help you get your system fully operational as quickly as possible. The following standard integration options are available for this system. Please consult Aerotech if you are unsure what level of integration is required, or if you desire custom integration support with your system.
|-TAS||Integration - Test as system
Testing, integration, and documentation of a group of components as a complete system that will be used together (ex: drive, controller, and stage). This includes parameter file generation, system tuning, and documentation of the system configuration.
|-TAC||Integration - Test as components
Testing and integration of individual items as discrete components that ship together. This is typically used for spare parts, replacement parts, or items that will not be used together. These components may or may not be part of a larger system.
