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.

Teflon Linear Bearings: Cut Friction by 70% and Maintenance Costs in Half – Free USA Shipping Samples

As a US-based operations manager or purchasing director, you're battling high downtime from lubricated bearings that seize under load. YIDI Motion's Teflon linear bearings deliver self-lubricating, maintenance-free performance for your automation lines.

The Hidden Costs Draining Your Linear Motion Budget

You know the drill: traditional metal or ball bearings demand constant upkeep, leading to unexpected failures in your CNC machines or robotic arms.

High Prices from US Suppliers: Premium brands charge up to $50 per unit, squeezing your ROI.
Low Quality from Cheap Imports: Inferior materials wear out 3x faster, causing 37% more downtime per industry reports.
Skyrocketing Shipping Costs: Cross-Pacific freight adds 20-30% to landed costs for bulk orders.
Frequent Lubrication Headaches: Downtime for re-greasing eats 15 hours per machine annually.
Friction-Induced Failures: High coefficients (0.2+) lead to heat buildup and premature wear in high-speed apps.
Supply Chain Delays: Lead times stretch to 12 weeks from competitors.
