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 Cam Roller Followers in US Manufacturing

As a purchasing manager or technical director in the USA, you face relentless pressure to keep production lines running 24/7. But subpar cam roller followers from unreliable suppliers are sabotaging your operations.

High Prices Eating into ROI: Imported components cost 30-50% more from European suppliers, straining your budget without proportional quality gains.
Low Quality Leading to Failures: Cheap alternatives wear out in under 6 months, causing 37% average downtime increase per industry reports from McKinsey.
Skyrocketing Shipping Costs: Delays from overseas freight average 45 days, with costs up 25% post-2026 tariffs—disrupting your just-in-time inventory.
Inconsistent Performance: Mismatched tolerances lead to vibration, noise, and reduced machine lifespan by 25%.
Lack of Customization: Off-the-shelf options don't fit your automation setups, forcing expensive modifications.
Poor After-Sales Support: No local presence means weeks for replacements, costing $5,000+ per incident in lost productivity.

These issues aren't hypothetical—AMT surveys show 62% of US manufacturers cite supply chain quality as their top concern in 2026. Ready to fix this? Discover YIDI's solutions below.
