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.

Why Your Current Pillow Block Linear Ball Bearings Are Failing USA Operations

As a purchasing manager in the USA manufacturing sector, you face relentless pressure to maintain uptime while slashing costs. But subpar bearings from competitors lead to disaster.

High Prices Eating ROI: Imported generics cost 20-40% more per unit without matching performance, per 2025 AMT industry reports.
Low Quality Causing Downtime: Inferior materials fail under loads over 5,000N, leading to 37% unplanned shutdowns – a $50K hit per incident for mid-size factories.
Skyrocketing Shipping Costs: Slow ocean freight from distant suppliers adds $2-5K per pallet, delaying projects by weeks.
Inconsistent Sizing: Mismatched tolerances cause vibration and wear, reducing machine life by 25%.
No Customization: Off-the-shelf units don't fit OEM needs, forcing expensive modifications.
Poor After-Sales: No local support means weeks of wait for replacements. Discover how YIDI fixes this →
