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 High Precision Ball Screws

As a purchasing manager in the USA manufacturing sector, you face relentless pressure to cut costs while maintaining precision. But unreliable suppliers lead to headaches.

High Prices Eating into ROI: Premium ball screws from competitors cost 30-50% more, squeezing your margins in competitive bids.
Low Quality Causing Failures: Inferior screws with poor lead accuracy (C5 or worse) result in 25% higher machine downtime per industry reports from AMT.
Skyrocketing Shipping Costs: Delays from overseas without optimized logistics add $5K+ per order in expedited fees.
Inconsistent Supply Chains: Stockouts during peak seasons halt production lines, costing $10K/hour in lost output.
Lack of Customization: Off-the-shelf options don't match your CNC or robotic arm specs, forcing expensive reworks.
Compliance Nightmares: Non-CE/RoHS certified parts risk FDA recalls or export bans to Europe.

Imagine your automation line grinding to a halt mid-shift. Don't let this happen. Scroll to see how YIDI solves it. Learn more now.
