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 Core Pain Points: Why Traditional Bearings Fail US Operations

As a purchasing manager in the US manufacturing sector, you know the stakes. High-speed applications demand bearings that won't quit under pressure—but competitors fall short.

1. Skyrocketing Prices: Premium ceramic bearings from European suppliers cost 30-50% more, eroding your ROI amid inflation pressures.
2. Inconsistent Quality: Low-grade imports lead to premature failures—a 2026 US industry report notes 25% of bearings fail within 6 months due to material flaws.
3. Crushing Shipping Costs: Delays from unreliable chains add $5,000+ per shipment to your bottom line, especially post-tariff hikes.
4. Long Lead Times: Waiting 12-16 weeks disrupts production schedules, costing up to $10K daily in downtime.
5. Limited Customization: Off-the-shelf options ignore your OEM needs, forcing compromises on precision.
6. Compliance Headaches: Navigating RoHS, FDA, and US import regs with unverified suppliers risks fines and recalls.

These issues hit hard in industries like aerospace, EVs, and pumps. Ready for bearings that solve this? Explore YIDI's advantages below.
