What Is a Ball Screw and How Does It Work?

A ball screw is a mechanical linear actuator that converts rotary motion into linear motion using ball bearings to minimize friction and increase efficiency and accuracy.

What Types of Ball Screws Do You Offer?

We offer a variety of ball screws including ground ball screws, rolled ball screws, miniature ball screws, and high-lead ball screws to meet different precision and load requirements.

How Do I Choose the Right Ball Screw for My Application?

Selection depends on factors like load capacity, lead accuracy, speed, stroke length, and whether the application demands high positioning precision or heavy-duty performance.

What Is the Difference Between Ground and Rolled Ball Screws?

Ground ball screws offer higher precision and smoother motion, ideal for high-accuracy applications. Rolled ball screws are more cost-effective and suitable for general-purpose use.

What Maintenance Is Required for a Ball Screw?

Regular lubrication is essential. Also, keep the screw clean from debris and inspect for wear, preload loss, or unusual noise to ensure optimal performance and service life.

Why Your Current Precision Linear Actuator Setup is Costing You Dearly

As a US operations manager in 2026, you're under pressure to optimize automation lines amid rising tariffs and supply chain disruptions. But high prices, inconsistent quality, and exorbitant shipping from unreliable suppliers are eroding your ROI.

High Prices: Overseas actuators often cost 30-50% more due to middlemen and markups, squeezing your budget.
Low Quality: Backlash exceeding 0.1mm leads to 25% failure rates in high-cycle applications, per industry reports from Automation World.
High Shipping Costs: Delays of 8-12 weeks from Asia inflate logistics by $5K per pallet, disrupting just-in-time manufacturing.
Unreliable Precision: Thermal drift and wear cause positional errors, impacting 15% of output in precision assembly.
Limited Customization: Off-the-shelf units fail to integrate with US servo systems, forcing costly redesigns.
Poor After-Sales: No local support means weeks of downtime for repairs.

These issues compound: a single line failure can cost $10K/day. Ready to fix this? Explore YIDI's solution below.
