Linear Motion Stages | Griffin Motion
Griffin Motion linear stages are available in both ball screw and linear motor drives. Rotary or linear encoders are offered on most product families. Travels from 50mm up to 1000mm are available. Customized travel lengths are possible upon request. Braking mechanisms can be added to most ball screw driven linear stages for added safety while operating in a vertical orientation. Mounting holes on most stages allow for easy stacking to create many combinations of custom multi-axis systems. Different levels of accuracy and resolution are offered to ensure that your precision needs are met at the most effective price point. Error mapping of stages can be implemented to improve the accuracy of most stages for demanding applications.

Quick Guide to Precision Linear Motion Stages
Precision linear motion stages are critical components in advanced automation, providing highly accurate, repeatable, and smooth single-axis positioning. At Griffin Motion, our linear stages are engineered to deliver uncompromising performance across a wide range of demanding applications, from nanotechnology to light industrial applications.
Drive Mechanisms: Ball Screw vs. Linear Motor
We offer linear stages equipped with two primary drive technologies, allowing you to optimize for speed, force, and price point:
- Ball Screw Driven Stages: Ideal for applications requiring high thrust, stiffness, and precise positioning. They are highly effective for vertical payloads, especially since braking mechanisms can be added to most of our ball screw stages to prevent back-driving and ensure equipment safety during power loss.
- Linear Motor Driven Stages: The premier choice for high-speed, high-acceleration, and ultra-smooth continuous motion. Because linear motors utilize a direct drive mechanism with no mechanical linkages to wear out, they offer exceptional longevity and zero backlash.
Customization and Multi-Axis Integration
We understand that standard solutions don't always fit complex engineering challenges. Our linear platforms feature standard travel lengths ranging from 50mm up to 1000mm, but customized travel lengths are readily available upon request. Furthermore, standardized mounting holes across most of our product families allow for seamless stacking. You can easily combine our linear stages to build custom XY stages, XZ, or XYZ multi-axis gantry systems tailored to your exact spatial and motion requirements.
Unmatched Accuracy for High-Tech Industries
Different applications require different levels of precision. We offer various grades of accuracy and resolution—integrating either rotary or linear encoders depending on the product family—to ensure your specifications are met at the most cost-effective price point. For ultra-precision requirements in industries like semiconductor processing, laser processing, optical inspection, and photonics, advanced error mapping can be implemented to drastically improve the absolute accuracy of the stage.
Frequently Asked Questions
What is the maximum travel length of your linear stages?
Our standard precision linear stages offer travel lengths ranging from 50mm up to 1000mm. If your specific application requires a longer stroke, we can engineer customized travel lengths upon request to meet your exact specifications.
Can these linear stages be used in a vertical (Z-axis) orientation?
Yes. For vertical positioning, we highly recommend our ball screw driven stages. To ensure equipment safety and prevent back-driving in the event of a power loss, braking mechanisms can be added to most of our ball screw stages to hold your payload securely in place.
How do I combine linear stages to create a multi-axis system?
Most of our linear stages are designed with standardized mounting hole patterns. This allows for direct, seamless stacking to create custom XY, XZ, or XYZ configurations without the need for cumbersome adapter plates in most standard setups.
What type of encoders are used for positioning feedback?
Depending on the product family and your specific precision requirements, we integrate either rotary or linear encoders. We offer various levels of resolution to hit your ideal price-to-performance ratio. For applications demanding the highest possible precision, we also offer advanced error mapping.
