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.

Premium Sliding Contact Bearings: Reduce Friction by 40% and Cut Downtime – OEM Customization for USA Manufacturers, Free Sample Available

As a US operations manager facing high prices, low quality bearings, and soaring shipping costs, you need reliable sliding contact bearings that deliver ROI fast. YIDI Motion's precision-engineered solutions from our powerful Hebei factory ensure seamless linear motion for your machinery.

No obligation – Ships to USA with full compliance

Why Sliding Contact Bearings Are Failing Your Operations in 2026

You know the frustration: machinery grinding to a halt due to unreliable bearings. In the USA manufacturing sector, sliding contact bearing failures account for 28% of unplanned downtime, per recent NIST reports.

High Prices Eating ROI: Premium brands charge up to $150 per unit, squeezing your budgets amid inflation.
Low Quality Leading to Failures: Inferior materials cause premature wear in under 6 months, costing $50K+ in repairs annually.
Skyrocketing Shipping Costs: Overseas delays add 30-50% to landed costs from non-optimized supply chains.
Lack of Customization: Off-the-shelf bearings don't fit your linear motion needs, forcing inefficient workarounds.
Compliance Headaches: Navigating RoHS, CE, and FDA regs for USA imports wastes weeks.
Slow Delivery Times: Wait 8-12 weeks for restocks, disrupting production lines.

Imagine slashing these pains with a supplier that guarantees quality at competitive prices. Ready for the solution?
