 About Linear Stages

Need to know a little bit more before you can make your XYZ translation stages decision? Below is additional information about linear stages and how they work. Contact us to speak with our staff who can answer any of your technical questions.

What are linear stages?


Linear motion stages provide precise automated positioning and are typically available as either single axis, an XY stage, or XYZ translation stages. Each axis of a linear stage must constrain the six degrees of freedom (X, Y, Z, roll, pitch, and yaw) of the payload to only one, producing translation along a straight line. This is accomplished with a set of linear bearing guideways which are attached to a base structural member that provides a stiff support.

The linear bearing guideways can be implemented in a number of ways, including:

  • Ball and crossed roller bearings
  • Recirculating bearings
  • Cam followers or vee wheels
  • Air bearings

How do linear translation stages work?

Once the payload has been constrained to a single degree of freedom, the system’s next mission is to actuate the payload and provide precise incremental linear motion along the guideway.

Linear actuator methods include:

  • Friction screws with anti-backlash nuts
  • Ball screws
  • Belt and pulley
  • Rack and pinion
  • Piezo actuators
  • Linear motors

Using a linear motor is generally considered to be optimal for high speed motion systems and is the most precise and repeatable linear motion actuation technology.

A linear translation stage with a linear motor requires a linear feedback device as well as a servo drive and control to close a position feedback loop. With a high-resolution linear encoder, linear actuators can provide position control down to the nanometer level. A typical application for high precision linear actuators is to control the focus of a microscope objective in a digital imaging system.
