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 Sourcing Small Gear Motors Frustrates U.S. Buyers in 2026

You need compact, reliable drives for automation lines, but traditional suppliers fall short. Here's what corporate purchasing managers like you face daily:

High Prices Eating ROI: Premium U.S./EU brands charge $50-150/unit, inflating your BOM by 25-40% vs. benchmarks from McKinsey's 2025 supply chain report.
Low Quality & Failures: Cheap imports fail after 1,000 hours, causing 37% unplanned downtime per Deloitte manufacturing study – your production halts, costs soar.
Skyrocketing Shipping: Delays of 8-12 weeks from Asia, plus tariffs, add 30% to landed costs. No quick prototypes for urgent projects.
No Customization: Off-the-shelf sizes don't fit your linear actuators or robotics arms, forcing redesigns.
Compliance Headaches: Missing UL/CE/RoHS certs block FDA-regulated apps in medical devices.
Unreliable Service: Poor communication, no after-sales – you're left with excess inventory of duds.
