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.

Why Your Current CNC Linear Rails Are Costing You Thousands

As a purchasing manager in the USA manufacturing sector, you face relentless pressure to cut costs while maintaining precision. But subpar CNC linear rail types from low-quality suppliers lead to disaster.

High Prices Eating ROI: Imported rails from competitors average $150-300 per meter, inflating your project budgets by 25-40% without proportional quality gains.
Low Quality Causing Downtime: Inferior ball or roller bearings wear out 2-3x faster, leading to 37% more machine stops per industry reports from AMT (Association for Manufacturing Technology, 2025).
Skyrocketing Shipping Costs: Overseas delays and duties add $50-100 per unit, with lead times stretching to 8-12 weeks for non-optimized supply chains.
Vibration and Inaccuracy: Poor preload and rigidity cause 0.05mm+ deviations in high-speed milling, scrapping 15-20% of parts.
Limited Customization: Off-the-shelf options ignore your specific CNC spindle loads, forcing compromises on speed and load.
After-Sales Nightmares: No local support means weeks of waiting for replacements, disrupting your 24/7 operations.

These issues aren't hypothetical – a 2025 Deloitte survey shows 68% of US manufacturers cite linear motion failures as top supply chain risks. Ready to fix this? Discover YIDI's solution below.
