The Primatics PZA25 Linear Stage is a compact, high-precision vertical positioning system designed for applications requiring controlled Z-axis motion with sub-micron level stability. Unlike traditional vertical lift stages, the PZA25 uses an engineered inclined-plane (wedge-based) mechanism that converts horizontal motion into precise vertical elevation.
This design enables exceptionally smooth motion while maintaining a low overall profile, making it ideal for systems where vertical space is limited but accuracy cannot be compromised.
Built for demanding environments such as semiconductor inspection, fiber optic alignment, precision assembly, and machine vision systems, the PZA25 delivers stable, repeatable vertical positioning with excellent rigidity and minimal off-axis error.
Its structure is optimized so that the load remains centered over the bearing system, reducing deflection caused by cantilevered loads and improving long-term mechanical stability.
Features
PZA25 Linear Stage Features
- Precision-Engineered Vertical Motion
The PZA25 is designed to replace traditional Z-axis lift systems with a more stable and compact mechanical architecture that improves both performance and reliability. - Inclined Wedge Motion System
Instead of moving vertically through a direct screw lift, the PZA25 uses a precision ball screw to drive a wedge mechanism. This converts horizontal motion into vertical displacement, producing highly controlled elevation with excellent repeatability. - High Stiffness Mechanical Design
The stage structure is engineered so the payload remains centered over the support bearings throughout motion. This significantly reduces deflection, especially under uneven or cantilevered loads. - Sub-Micron Precision Performance
With precision machining and high-quality linear bearings, the PZA25 achieves sub-micron repeatability, making it suitable for optical alignment, wafer inspection, and other ultra-precise processes. - Integrated Motion Components
Standard features include limit switches and a home reference position, allowing seamless integration into automated control systems. These features improve safety, repeatability, and system calibration. - Flexible Motor Integration
The platform supports both stepper and servo motor configurations, giving engineers flexibility to balance speed, torque, and resolution depending on application needs. - Clean Mechanical Profile
The low-height structure allows the PZA25 to fit into compact automation systems while still maintaining high structural rigidity and precision alignment capability.
