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 Linear Motion Stage Selection

1. Balancing Precision vs. Cost

High-accuracy stages (e.g., ±1µm repeatability) often come with premium price tags from brands like Thorlabs or Parker. You need sub-micron performance without the 50-100% markup.

YIDI’s Solution: German/Japanese-machined components at 30% lower costs via direct factory supply chains.

2. Compatibility with Existing Systems

Mismatched encoder resolutions, motor interfaces, or mechanical mounts can derail integration. 68% of engineers report delays due to incompatible stages (2026 Automation World survey).

YIDI’s Solution: Plug-and-play adapters for 90% of major motion control brands, plus custom CAD modeling.

3. Lead Times & Supply Chain Risks

Global shortages (e.g., ball screws, servo motors) extend lead times to 12-20 weeks for custom stages. Your production line can’t wait.

YIDI’s Solution: 10,000+ sq. ft. warehouse in Shijiazhuang with 2,000+ SKUs in stock. 15-day delivery for standard models.

Frequently Asked Questions

❓ What’s the difference between a linear stage and a linear actuator?

A linear stage is a precision positioning system with guided motion (e.g., dovetail, linear guides) and often includes feedback encoders. A linear actuator is a mechanical device that converts rotary to linear motion (e.g., screw, belt, or piston) but may lack precision guidance.

YIDI offers both—our stages integrate actuators with high-precision rails for sub-micron accuracy.

❓ How do I choose between a ball screw and lead screw stage?

Ball Screw: Best for high precision (±0.5µm), high loads (up to 500kg), and long life (50,000+ hours). Ideal for CNC, semiconductor, and metrology.

Lead Screw: More cost-effective (40% cheaper), quieter, and self-locking. Suitable for light loads (<50kg) and low-speed applications.

YIDI’s recommendation: Use our configuration tool or consult our engineers for a free assessment.
