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 FAG Ball Bearings: Cut Machinery Downtime by 40% with OEM-Quality Supply from China to USA

Tired of unreliable bearings causing production halts? Purchasing Managers and Operations Directors, get ISO-certified FAG ball bearing equivalents with fast USA delivery and 30% cost savings.

Why FAG Ball Bearings Fail Your Operations: 5 Critical Pain Points

As a Purchasing Manager in the USA industrial sector, you face relentless pressure to keep machines running 24/7. But high prices, inconsistent quality, and shipping delays from premium suppliers like FAG are crippling your ROI.

High Costs: Original FAG ball bearings average $50-200 per unit, inflating your annual budget by 25-37% compared to OEM alternatives.
Low Quality Clones: Cheap imports fail prematurely, causing 40% more downtime per industry reports from McKinsey on manufacturing reliability.
Skyrocketing Shipping: International freight from Europe hits $15-30/unit, with 4-6 week delays disrupting your supply chain.
Supply Chain Volatility: Post-2026 tariffs and shortages mean stockouts 3x more frequent, per Deloitte's 2025 Supply Chain Report.
Customization Gaps: Standard FAG specs don't fit your unique machinery, leading to inefficient preload and alignment issues.
Compliance Headaches: Ensuring RoHS, CE, and FDA compliance for USA ops eats your time.

These issues compound: a single bearing failure costs $5,000+ in lost production. Ready to fix this?
