Linear Ball Screw & Lead Screw Actuators

Benefits of Using a Ball Screw Stage in Automation

Screw-driven linear actuators—whether ball screw or lead screw type—offer an excellent balance of performance, cost, and integration flexibility for OEMs, machine builders, and integrators. At Valin Corporation, our portfolio of linear ball screw and lead screw actuators delivers proven performance for a wide range of applications—from high-thrust, long-travel modules to compact, light-duty embedded systems.

Screw-driven actuators convert rotary motor motion into linear translation via a screw and nut assembly. In ball screw designs, recirculating balls reduce friction and deliver higher efficiency and load capacity; lead screw designs offer simpler, cost-efficient solutions for moderate loads and lower duty cycles.

Use these actuators when you need:

  • Controlled, repeatable motion with moderate to high force
  • Defined travel length (including rod, rodless, slider, stage, and other form-factors)
  • Flexibility of motor mounting, feedback integration, custom stroke, and mounting interfaces
  • Cost-effective performance when ultra-high speeds or sub-micron, direct-drive control are not required
  • Because Valin supports both ball screw and lead screw technologies, we help you select the right screw drive train for your performance, cost, and reliability trade-offs.

How to Choose the Right Actuator for Your Application

Knowing which actuator to select starts with understanding your loading, speed, travel and precision requirements.  The LOSTPED acronym is very handy with this.  Learn more about the Load, Orientation, Speed, Travel, Precision, Environment and Duty Cycle requirements in LOSTPED: What to Know About Selecting Mechanics.

Maintenance Tips to Extend the Lifespan of Your Actuator

  • Make sure it is sized properly.
  • Minimize the moment loading applied to it.
  • Lubricate it periodically if it doesn’t include self-lubricating mechanical components; consult the user or maintenance manual for the specific actuator.
  • Keep it free from contamination.
  • If the shorts are repeated very short strokes that are less than the circumference of the ball bearings, then occasionally move it with longer travel to properly lubricate the ball bearings.

Q & A

Linear Ball Screw & Lead Screw Actuators Q & A

+ How do ball screw and lead screw actuators differ from linear motor and belt & pulley actuators? 
Screw-driven actuators use a rotating mechanism with grooves to move a nut linearly.  Linear motor actuators use copper coils to control linear motion along magnets laid out in a linear track.  Belt & pulley actuators use a rotary gear or pinion, or pulley to move a belt that moves a carriage and load along linear bearings.  Learn more in Episode 15 of The Motion Control Show: Ball screw Actuators vs Belt Pulleys vs Linear Motors
 
+ What is the difference between ball screw and lead screw actuators? 

A ball screw actuator uses recirculating ball bearings in the nut-screw interface with U-shaped grooves to convert rotational motion to linear, resulting in lower friction, higher efficiency, better life, and typically less backlash. Lead screw actuators may use sliding or rolling contact with a threaded nut on a screw with V-shaped grooves, which is simpler and more cost-effective but may have higher friction or wear.

Under enough load, such as vertical applications, ball screw actuators will back-drive if there is no holding torque or brake on it.  Lead screws will not which is why, especially for vertical loads, lead screw actuators are more attractive.

 
+ When should I choose a ball screw actuator over a lead screw?  

Choose a ball screw when your application demands long life, high duty-cycle, higher thrust, low friction, and high repeatability. Choose a lead screw when cost, simpler mechanism, lower speed/force, or smaller size are more critical. The best choice depends on your application metrics (force, speed, travel, cycle life, cost) rather than a one-size-fits-all. 

+ Are screw-driven actuators suitable for multi-axis stacks and gantry systems?  

Yes. Screw-driven actuators (ball screw or lead screw) can be integrated into X-Y, X-Y-Z, or gantry configurations, with proper guidance, motors, control, and cabling. While linear motors often dominate ultra-high-speed or sub-micron axes, screw-driven actuators provide excellent value for many machine motion axes.  

+ What about backlash and maintenance in screw actuators? 

Backlash is a common concern—ball screw pre-load or anti-backlash nuts mitigate it. Maintenance depends on environment and duty; ball screws typically require less frequent service than sliding-nut lead screws. The correct sizing and interface selection is key.  

+ Why choose Valin as your partner for screw-driven linear actuators?  

Valin brings deep motion-control system expertise (the three-tier framework: basic → precision → beyond), a broad actuator product portfolio (ball screw, lead screw, linear motors), OEM application know-how (especially in the Western US region), integration support, custom sizing & engineering assistance. We help you avoid selecting “because it looks cheap” and instead select “because it meets the real motion system metrics”.  

+ What are the key components and their roles in motion systems? 

Each ball screw and lead screw positioning system consists of essential components that directly impact performance and reliability:

  • Ball screw or lead screw: converts rotary motion into linear motion.
  • Guide rails: ensure smooth and precise linear travel.
  • Carriage, Stage, or Slide Table: supports the load and attaches to the end-effector or tooling.
  • Motor and Drive system: determines the motion profile, speed, and control interface.
  • Linear encoder: an option feedback device that enhances system accuracy in closed-loop systems.
