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 Screw Support Units Are Failing You

In 2026, with U.S. manufacturing ramping up under reshoring initiatives, downtime from poor linear motion components can cost you $50,000+ per incident. Here's what purchasing managers like you face daily:

High Prices from Premium Brands: Name-brand supports cost 2-3x more, eating into your ROI without proportional gains.
Low Quality from Budget Suppliers: Cheap imports fail prematurely, leading to 37% higher failure rates per industry reports from AMT.
High Shipping Costs & Delays: Overseas sourcing without optimized chains means 4-6 week waits and 15-20% extra logistics fees.
Inconsistent Tolerances: Misalignments cause vibration, reducing precision by up to 25% in high-speed apps.
Limited Customization: Off-the-shelf units don't fit OEM designs, forcing workarounds.
Poor After-Sales Support: No quick replacements, leaving your lines idle.

These issues aren't hypothetical—78% of U.S. manufacturers report linear motion failures as top concerns (Rockwell Automation 2025 Survey). Ready for a fix? Discover YIDI's solution below.
