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 Challenges with Linear Motion Systems

Purchasing managers and engineers often face these linear actuator screw pain points:

High Costs: Ball screws offer precision but come at a premium (up to 40% more than lead screws). Balancing budget and performance is critical.
Precision Loss: Lead screws may suffer from backlash (>0.1mm), compromising accuracy in CNC or robotics applications.
Premature Wear: Low-quality screws degrade after 5,000 hours, causing downtime. Lifespan depends on material (e.g., stainless steel vs. carbon steel).
Compatibility Issues: Mismatched screw pitch (e.g., 5mm vs. 10mm) or diameter (12mm–60mm) can derail entire motion systems.
Lead Times: Custom screws from overseas suppliers often take 4–6 months, delaying production.

Solution: YIDI Motion’s linear actuator screws deliver German-Japanese precision at Chinese production costs, with 30-day expedited shipping.

Ball Screw vs. Lead Screw: Which is Right for You?

Choosing between ball screws and lead screws depends on your application:

✅ Ball Screws

Efficiency: 90% (vs. 20–40% for lead screws).
Load Capacity: Up to 50kN dynamic load.
Lifespan: 10,000+ hours with proper lubrication.
Best For: High-speed, high-precision CNC machines, semiconductor equipment.

✅ Lead Screws

Cost: 60% cheaper than ball screws.
Self-Locking: No back-driving (ideal for vertical applications).
Maintenance: Lower lubrication needs.
Best For: Low-speed, high-torque applications (e.g., 3D printers, lab equipment).

YIDI Tip: For hybrid needs, our rolled ball screws offer 80% of precision at 50% of the cost of ground ball screws.

FAQ: Linear Actuator Screw Selection & Customization

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

Answer: Opt for a ball screw if you need high precision (>0.01mm), high speed, or long lifespan. Choose a lead screw for cost-sensitive, low-speed, or self-locking applications.

❓ What’s the maximum load capacity for your screws?

Answer: Our ball screws handle up to 50kN dynamic load (e.g., 20mm diameter, C5 grade). Lead screws support 10kN (varies by material and pitch).

❓ Can you customize screw pitch and diameter?

Answer: Yes! We offer pitches from 1mm–20mm and diameters from 6mm–80mm. Submit a drawing for a quote.

❓ How fast can you deliver custom orders?

Answer: Standard orders: 90 days. Expedited: 30–45 days (additional fee applies).

❓ Do you provide samples?

Answer: Yes! We offer free samples (shipping costs apply). Request via our contact form.

❓ What payment methods do you accept?
