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 US Manufacturers Struggle with Linear Actuators – Core Pain Points Exposed

As a US operations manager, you're under pressure to optimize production lines. But subpar linear actuators from competitors lead to headaches. Here's what you're facing:

High Prices Eating ROI: Premium brands charge $500+ per unit, slashing your margins by 25% without proportional performance.
Low Quality & Failures: Cheap imports fail after 10,000 cycles, causing 37% unplanned downtime per McKinsey automation reports.
Skyrocketing Shipping Costs: Delays from Asia average 45 days + $200/unit fees, disrupting just-in-time inventory.
No Customization: Off-the-shelf models don't fit unique automation needs, forcing expensive retrofits.
Poor After-Sales: No local support means weeks of downtime for repairs.
Compliance Risks: Actuators lacking UL/CE certs expose you to FDA/OSHA fines up to $14,000 per violation.

These issues cost US firms $1.2 trillion annually in manufacturing inefficiencies (Deloitte, 2025). Ready for a fix? Scroll to solutions.
