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.

Your Core Pain Points with Traditional Bearing Suppliers

In 2026, USA industrial managers like you face escalating pressures: machinery downtime costs average $260,000 per hour (per Aberdeen Group research), yet suppliers fail to deliver.

High Prices: Premium special bearings from competitors hit $150-300/unit, eroding your margins by 25-37%.
Low Quality: Inferior materials lead to 20-30% failure rates within 6 months, causing unplanned shutdowns.
High Shipping Costs: Ocean freight from Asia adds $50-100/unit + 4-6 week delays, disrupting your supply chain.
Lack of Customization: Off-the-shelf bearings don't match your high-load, high-speed needs, forcing compromises.
Poor Service: No OEM/ODM support means endless iterations and communication barriers.
Reliability Gaps: Without quality assurance, you're risking warranty claims and recalls.

Imagine slashing these issues—read how our special bearings deliver.
