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 Curved Rack and Pinion Systems

In 2026, US manufacturers demand flawless curved motion for automation. Yet, sourcing a reliable curved rack and pinion gear remains a headache.

High Prices Eating ROI: Competitors charge 40-50% premiums for off-the-shelf parts, squeezing your margins.
Low Quality Leading to Failures: Inferior materials cause 25% downtime in high-speed applications like packaging lines.
Skyrocketing Shipping Costs: Delays from overseas suppliers add $5K+ per order and weeks to lead times.
Customization Gaps: Standard straight racks don't fit curved paths in robotics or solar trackers, forcing costly redesigns.
Integration Nightmares: Poor tolerances (DIN 8+) lead to backlash and vibration in precision systems.
Supply Chain Risks: China's volatile logistics disrupt your operations—37% of managers report delays per recent Gartner data.

These issues cost you time and money. What's your next move? Discover how YIDI Motion fixes them. Scroll to solutions →
