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.

The Hidden Costs Plaguing Your Rotary Stage Operations

You're a purchasing manager in the USA manufacturing sector, dealing with automation lines that demand pinpoint rotation accuracy. But subpar rotary stages from competitors are costing you dearly. Here's why:

High Prices Without Value: Premium brands charge 30-50% more for similar specs, squeezing your ROI in tight budgets.
Low Quality Leading to Downtime: Inferior build causes ±10 arc-sec backlash, resulting in scrap rates up to 15% in precision assembly, per IndustryWeek reports.
Skyrocketing Shipping Costs: Delays from overseas suppliers average 8-12 weeks, with duties inflating costs by 25% – imagine your production halt at $47,000/hour (Uptime Institute data).
No Customization: Off-the-shelf rotary positioning tables fail to integrate with your linear guides or ball screws, forcing expensive retrofits.
Unreliable After-Sales: No local support means weeks for repairs, disrupting your supply chain.
Compliance Headaches: Non-USA compliant stages risk FDA/CE violations in regulated industries like optics and pharma.

These issues compound: a single failed batch can erase quarterly profits. Ready for a fix? Scroll to our solution.

Key Performance Notes: Resolution refers to the smallest angular step (e.g., 0.01 arc-sec = 1/360,000 degree), measured via laser interferometer. Accuracy is positional repeatability under 1kg load. All models support vacuum-rated options for cleanrooms and IP65 sealing for harsh environments. Backlash <0.5 arc-sec via preloaded worm gears. Torque up to 50Nm on larger models, integrating seamlessly with our ball spline or linear actuators.
