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 Current Linear Actuators Are Costing You More Than You Think

As a purchasing manager or operations lead in the USA, you're under pressure to optimize supply chains amid rising costs. But unreliable linear actuators from generic suppliers create hidden headaches.

High Prices from Western Brands: Premium European or US actuators charge 2-3x more, eating into your ROI—up to $500 extra per unit.
Low Quality from Budget Chinese Suppliers: Cheap imports fail prematurely, causing 37% higher downtime according to industry reports from Automation World (2025).
Skyrocketing Shipping Costs: Delays from overseas factories mean 4-6 week waits, inflating logistics by 25% amid 2026 global disruptions.
Poor Customization: Off-the-shelf designs don't match your automation needs, leading to integration failures.
Unreliable Service: No OEM/ODM support means you're stuck with stock limitations and zero after-sales help.
Compliance Risks: Non-certified products risk FDA/CE violations in regulated industries like packaging and medical devices.

Imagine slashing these issues—keep reading for proven fixes.
