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.

3 Critical Challenges in Precision Motion Systems

1. High Costs of Premium Rails

OEMs pay 20–40% markups for branded MGN12H rails. YIDI’s factory-direct model cuts middlemen, passing savings to you.

2. Inconsistent Tolerances

Low-grade rails cause ±0.05mm deviations, ruining CNC precision. Our German/Japanese equipment ensures ±0.01mm accuracy.

3. Long Lead Times

Competitors take 120+ days. YIDI’s 100-employee team + automated lines deliver in 90 days or less.

YIDI solves these with: Factory prices | High-precision manufacturing | Rapid delivery
