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 Biggest Challenges as a USA Operations Manager Sourcing Ball Screws

In 2026, with supply chain disruptions still echoing from recent global events, 68% of USA manufacturers report delays in linear motion components like DFU ball screws.

High Prices Eating into ROI: Premium USA suppliers charge up to 40% more, squeezing your budgets without proportional quality gains.
Inconsistent Quality Leading to Failures: Low-grade imports cause 25-30% higher failure rates in high-precision applications, resulting in costly recalls.
Prohibitive Shipping Costs & Delays: Ocean freight from Asia averages $5,000+ per pallet with 45-day waits, halting production lines.
Lack of Customization: Off-the-shelf ball screws don't match your CNC or robotic specs, forcing inefficient workarounds.
Compliance Nightmares: Navigating RoHS, CE, and FCC for USA imports risks fines and customs holds.
Poor After-Sales Support: No local tech assistance means weeks of downtime troubleshooting.

These issues compound, driving up total ownership costs by 52% according to a 2025 McKinsey report on industrial automation.
