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 Guides Are Costing You Dearly

As a US operations manager, you face relentless pressure to boost ROI on automation equipment. But subpar high precision linear guides derail that goal.

High Prices Eating Margins: Imported guides from competitors hit 25-40% above market, squeezing your budget without proportional quality.
Low Quality Leading to Failures: Inferior materials cause 28% more friction and wear, triggering unexpected breakdowns in CNC mills or robotic arms.
Skyrocketing Shipping Costs: Delays from unreliable China suppliers add $5K+ per order in expedited freight to the USA, plus customs headaches.
Inconsistent Precision: Positional errors over 0.01mm ruin tolerances in high-speed applications like semiconductor assembly.
Long Lead Times: 12+ week waits halt production lines, costing $10K/day in lost output.
No Customization: Off-the-shelf options fail to match your OEM needs, forcing expensive workarounds.

These issues compound: a single guide failure cascades into 40% downtime spikes. Ready for a fix? Discover YIDI's solution below.
