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.

3 Critical Pain Points US Buyers Face with Linear Guide Rails

You're not alone: 68% of US operations managers report downtime from rail failures, per a 2025 Automation World survey.

High Prices: Imported HGR15 linear rails from premium brands cost 2-3x more, squeezing your ROI amid 2026 tariffs.
Low Quality & Failures: Cheap China-sourced options warp under load, causing 37% higher scrap rates in CNC ops.
Skyrocketing Shipping Costs: Delays average 6-8 weeks, with fees up 25% post-pandemic – disrupting your supply chain.
Inconsistent Service: No OEM/ODM flexibility means custom fits take months.
Quality Variability: Rails lack certifications, risking non-compliance in US factories.
Slow Delivery: Competitors' lead times hit 45 days, halting production lines.

These issues cost you $50K+ annually in lost productivity. But there's a fix – keep reading.
