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 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.

Precision Ground Ball Screw Manufacturer: Achieve C0-C3 Precision with OEM Customization in 4 Weeks

Q: 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.

As a U.S. operations manager, you're battling high costs and unreliable suppliers for linear motion components. YIDI Motion delivers precision ground ball screws that cut friction by 90% and boost machine uptime—tailored for CNC, robotics, and automation.

Why U.S. Manufacturers Struggle with Ball Screws Today

In 2026, supply chain disruptions hit 68% of U.S. manufacturers (per Deloitte's 2025 report), amplifying pain points for precision components like ball screws.

1. Skyrocketing Prices: Imported ball screws cost 40-60% more due to tariffs and markups from competitors.
2. Inconsistent Quality: Rolled alternatives fail C5 precision standards, causing 25% higher wear in high-speed CNC apps.
3. Prohibitive Shipping Delays: 8-12 week lead times from Asia inflate inventory costs by 30%.
4. Limited Customization: Off-the-shelf options ignore your OEM needs, leading to integration failures.
5. Reliability Gaps: Poor backlash control increases downtime by 15% in automation lines.
