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.

Core Pain Points: Why Your Current Rotary Table Bearings Are Costing You Dearly

As a purchasing manager in the USA manufacturing sector, you face relentless pressure to cut costs while maintaining precision. But subpar rotary table bearings from competitors lead to hidden expenses.

High Prices Without Value: Premium brands charge 30-50% more, yet deliver average performance – eroding your ROI.
Low Quality & Frequent Failures: Inferior bearings cause 25% higher downtime, with vibration issues in CNC rotary tables leading to scrapped parts.
Escalating Shipping Costs: Overseas suppliers delay deliveries by 6-8 weeks, inflating logistics by 20% amid USA tariffs.
Inconsistent Precision: Off-spec tolerances (±10μm) ruin high-precision machining, forcing costly recalibrations.
Limited Customization: No OEM/ODM options mean retrofitting, adding 15% to project timelines.
Poor After-Sales: No local support means weeks of downtime for replacements.

Industry data from McKinsey's 2025 Manufacturing Report shows bearing failures cost USA firms $12B annually. Ready to fix this? Discover YIDI's solution below.
