Linear Positioning Stage

Product Specifications

Technical details and manufacturing context for Linear Positioning Stage

Definition

A linear positioning stage is a precision mechanical component used in industrial machinery to provide controlled linear motion along a single axis. It is typically integrated into larger systems, such as correction units, where it positions optical elements, sensors, or other components with high accuracy. The stage enables correction of alignment errors, thermal drift, or other positional inaccuracies, ensuring reliable operation of the overall system.

The stage consists of a moving carriage mounted on linear guides, such as rails or ball screws. A drive mechanism, which may include a stepper motor, servo motor, or piezoelectric actuator, provides the force to move the carriage. A position feedback system, such as a linear encoder or laser interferometer, measures the actual position of the carriage. This feedback allows a controller to compare the actual position with the target position and make necessary corrections, achieving high-precision linear positioning.

Typical specifications for such stages include a travel range of 50–300 mm, load capacity of 10–50 kg, positioning accuracy of ±0.01–±0.05 mm (per ISO 230-2), and repeatability of ±0.003–±0.01 mm (per ISO 230-2). Maximum speed ranges from 100–500 mm/s. Drive types include ball screw or lead screw, and motor types include stepper or servo. Motor voltage is typically 24–48 V DC for stepper motors, while servo motors may require AC. Operating temperature is 0–50 °C, and ingress protection ranges from IP40 to IP54 (per IEC 60529). Materials are typically aluminum alloy or stainless steel, with weight ranging from 2–15 kg.

These values are reference ranges and must be verified with the manufacturer for specific models and applications. Standards listed are for verification purposes and do not imply certification. Always consult the supplier for detailed specifications and compliance information.

Working Principle

The linear positioning stage operates by converting rotational motion from a motor into linear motion of a carriage. The carriage moves along linear guides, and a lead screw or ball screw translates the motor's rotation into precise linear displacement. A position feedback device, such as an encoder, continuously monitors the carriage position. The controller compares this feedback to the desired position and adjusts the motor input to minimize error, enabling accurate and repeatable positioning.

Frequently Asked Questions

What is the typical travel range of a linear positioning stage?

The travel range is typically 50–300 mm, but custom lengths may be available. Confirm the exact range with the manufacturer for your specific model.

What factors affect positioning accuracy?

Positioning accuracy depends on the screw grade and the feedback system. The reference accuracy is ±0.01–±0.05 mm per ISO 230-2. Verify the actual accuracy with the supplier.

Can the stage be used in dusty or wet environments?

The ingress protection rating ranges from IP40 to IP54 per IEC 60529. Higher IP ratings are suitable for dusty or wet conditions. Check the specific rating for your application.

What materials are available for the stage?

The stage is available in aluminum alloy or stainless steel. Aluminum is lighter, while stainless steel offers higher rigidity. Choose based on your weight and stiffness requirements.
