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 Biggest Challenges with Custom Ball Screw Bearings

In high-precision manufacturing, custom ball screw bearings are critical for linear motion systems. But US buyers face ongoing issues.

High Prices: Domestic suppliers charge 30-50% more due to labor costs, squeezing your ROI. 37% of managers report budget overruns from premium pricing (IndustryWeek 2025).
Low Quality: Off-the-shelf bearings fail prematurely, causing 40% more downtime in CNC spindles and robotic arms.
High Shipping Costs: Long lead times from Europe add $5K+ per order, delaying projects by weeks.
Inconsistent Customization: OEM/ODM specs rarely match, leading to vibration and accuracy loss in high-speed apps.
Supply Chain Disruptions: Post-2025 tariffs hit 25% of imports, inflating costs unpredictably.
Poor After-Sales: No local support means weeks for replacements.
