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 Linear Motion Challenges You Face

As an operations manager or technical director, you need motion solutions that won't fail under pressure. Here are the top 5 pain points we solve daily:

1. Premature Wear

Low-quality rack and pinion systems degrade after 10,000 cycles. YIDI's hardened steel lasts 5x longer with proper lubrication.

2. Positioning Errors

±0.1mm inaccuracies cost you in precision applications. Our linear rack and pinion maintains ±0.02mm repeatability.

3. Load Capacity Limits

Standard systems buckle at 500kg. YIDI's heavy-duty versions handle 2,000kg+ with ease.

4. Maintenance Downtime

Weekly lubrication requirements kill productivity. Our sealed designs need maintenance every 6 months.

5. Integration Headaches

Custom mounting plates add $5,000+ to projects. We offer free CAD models and pre-engineered adapters.

Linear Rack and Pinion FAQs

❓ What's the difference between a linear rack and pinion and a ball screw?

The main differences are in load capacity, speed, and stroke length. Linear rack and pinion systems offer:

Higher speeds (up to 5 m/s vs 1 m/s for ball screws)
Unlimited stroke length (ball screws are limited by screw length)
Better cost-performance for long strokes (30-50% cheaper)
Lower maintenance requirements

However, ball screws offer better positioning accuracy (±0.01mm vs ±0.02mm for rack and pinion).

Rack And Pinion Driven Module

❓ How do I select the right module for my application?

Module selection depends on:

Load requirements: Higher modules (4-10) for heavier loads
Speed needs: Lower modules (1-3) for higher speeds
Precision: Smaller modules offer better precision
Noise levels: Helical racks (module 1-2) are quieter
