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 Systems

Industrial engineers and procurement managers face recurring issues when sourcing linear pillow blocks for precision applications:

❌ Premature Wear & Friction

Low-quality materials or poor lubrication lead to increased torque and shortened lifespan, causing costly downtime.

❌ Misalignment Issues

Standard pillow blocks lack self-aligning capabilities, requiring excessive adjustments during installation.

❌ Limited Load Capacity

Many suppliers offer generic solutions that fail under heavy radial or axial loads, risking system failure.

YIDI Motion addresses these with German/Japanese-grade materials, self-lubricating designs, and load ratings up to 5,000 N.

YIDI Linear Pillow Blocks: Engineered for Performance

Our mounted linear bearings outperform competitors like THK and HIWIN in three key areas:

Linear Pillow Block FAQ

❓ What’s the difference between a linear pillow block and a linear guide?

Linear pillow blocks are mounted bearings for radial loads on round shafts, ideal for low-cost, simple motion. Linear guides use recirculating balls on rails for higher precision/loads but cost 3–5x more.

❓ How do I select the right shaft diameter?

Match the shaft to your load: 12–20mm for light-duty (3D printers), 25–30mm for CNC routers, and 40mm+ for heavy machinery. Use our load calculator.

❓ Can you provide CAD models for custom designs?

Yes! We offer STEP/IGES/DWG files for all OEM orders. Turnaround: 24–48 hours.

❓ What’s your MOQ and lead time?

MOQ: 10 units (mixed models accepted). Lead time: 7–15 days for stock items, 20–30 days for custom orders.
