What Is an Inverted Translating Ball Screw Actuator?

An inverted translating ball screw actuator converts rotary motion into linear motion by translating the screw while the housing remains stationary.

Ball screw actuators move loads more efficiently than traditional machine screw actuators, allowing for:

  • Faster operation
  • Reduced friction
  • Lower power requirements
  • Longer life under load

When This Actuator Is the Right Choice

Use an inverted translating ball screw actuator when your application requires:

  • High-speed linear motion
  • Efficient force transmission
  • Precise, repeatable positioning
  • Frequent or continuous operation

Typical Applications

Used in applications where speed, efficiency, and precise control are critical.

  • Automation and material handling systems
  • Industrial machinery requiring high efficiency
  • Positioning and alignment systems
  • Applications with dynamic or continuous movement

Built to Match Your Application

To accommodate varying application requirements, multiple configuration options are available, including screw end types and travel control features.

Customization options include:

  • Lifting capacity (500 lbs to 50 tons)
  • Motor type (electric, hydraulic, pneumatic)
  • Stroke length
  • Screw end configurations (plain, threaded, clevis, top plates)
  • Limit switches for travel control

Multiple actuators can be synchronized for applications requiring coordinated movement.

Common Questions

A ball screw actuator is a good choice when your application requires faster motion, higher efficiency, and more precise positioning than a traditional machine screw actuator.

An inverted translating design allows the screw to move linearly while the housing remains stationary. This can be useful when the application requires compact installation, precise movement, or controlled motion in a specific direction.

Ball screw actuators are more efficient, faster, and better suited for dynamic movement. Machine screw actuators are typically slower but may be preferred when self-locking or static load holding is required.

Yes. Multiple actuators can be synchronized for applications that require coordinated lifting, positioning, or movement across multiple points.

Key factors include load capacity, travel length, speed, duty cycle, input RPM, mounting configuration, and whether the application requires braking or load holding.

Yes. Actuator speed, load capacity, duty cycle, and configuration should be reviewed carefully. The actuator should not be overloaded, and input speed limits should be followed to protect the system and application.
