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.

Common Pain Points in Sourcing Mini Ball Screws

Engineers and procurement managers face critical challenges when sourcing mini ball screws for precision applications. Here’s what keeps them up at night:

Inconsistent Precision: Many suppliers fail to maintain ±0.01mm tolerances, leading to positioning errors in CNC machines or robotics.
Long Lead Times: Waiting 12+ weeks for custom mini ball screws disrupts production schedules—especially for urgent OEM projects.
High MOQs: Most manufacturers enforce 100+ unit minimums, forcing buyers to overstock or compromise on specifications.
Limited Customization: Off-the-shelf options rarely fit unique lead, diameter, or material requirements (e.g., stainless steel for medical devices).
Hidden Costs: Unexpected fees for tooling, testing, or expedited shipping inflate budgets by 20-40%.
Quality Control Gaps: 30% of buyers report receiving defective batches due to inadequate inspection (source: 2026 B2B Industrial Buyers Report).

At YIDI Motion, we solve these issues with German/Japanese machined components, 100% pre-shipment testing, and MOQs as low as 10 units.
