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 US Manufacturers Struggle with Thin Wall Bearings

As a US operations manager, you're facing skyrocketing machinery downtime and budget overruns. High prices from domestic suppliers eat into your ROI, while low-quality imports fail prematurely.

Pain Point 1: Premium thin wall bearings cost 2-3x more from US brands, forcing compromises on precision robotics or aerospace apps.
Pain Point 2: Inferior alternatives lead to 45% higher failure rates per industry reports from ABMA (American Bearing Manufacturers Association), hiking maintenance by $50K/year.
Pain Point 3: Shipping costs from Asia average $15-20/kg, delaying projects by weeks and inflating landed costs by 25%.
Pain Point 4: Lack of OEM customization means off-the-shelf fits don't match your high-speed linear motion needs.
Pain Point 5: Unreliable supply chains cause stockouts during peak production, risking $100K+ in lost revenue.
