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.

Your Planetary Screw Challenges: High Costs, Failures, and Delays

In 2026, US manufacturers struggle with planetary screw sourcing amid rising tariffs and supply chain disruptions. Here's what you're likely facing:

High Prices: Premium US/EU brands charge 2-3x more than needed—up to $500 per unit for standard high-load models.
Low Quality & Early Failures: Inferior rollers cause 37% higher downtime per industry reports from AMT, eroding ROI.
High Shipping Costs: Overseas freight from scattered suppliers adds $200-500/unit, delaying projects by weeks.
Long Lead Times: Custom planetary roller screws take 12-16 weeks, missing tight production schedules.
Limited Customization: Off-the-shelf options fail high-load automation needs, forcing compromises.
Compliance Risks: Varying RoHS/CE standards lead to import headaches in the USA.

These issues cost operations managers like you thousands in lost productivity. Ready for a fix? Read on for YIDI's solution.
