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 CNC Operations Are Suffering from Poor Stepper Motor Choices

In 2026, U.S. manufacturers face intensified pressure: supply chain disruptions from competitors in Price, Service, and Quality, plus China's efficient supply chain advantages you're missing out on.

Pain Point 1: High Prices – Overpaying 30-50% for branded NEMA motors from U.S. distributors, eroding your ROI.
Pain Point 2: Low Quality – Motors with weak holding torque fail under load, causing 15-20% downtime in CNC routers and mills.
Pain Point 3: High Shipping Costs – Slow ocean freight adds $500+ per order, delaying your production timelines.
Pain Point 4: Inconsistent step resolution leads to imprecise cuts, scrapping 10% of parts.
Pain Point 5: Limited OEM/ODM options force generic fits, not optimized for your CNC spindle or axis needs.
Pain Point 6: After-sales headaches – no quick replacements for faulty drivers or windings.
