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 Ring Bearings Are Causing Headaches for US Manufacturers

You rely on ring bearings (also known as slewing ring bearings or turntable bearings) for smooth rotation in cranes, excavators, wind turbines, and robotics. But current suppliers fall short.

High Prices: Premium brands charge up to $5,000+ per unit, eroding your ROI.
Low Quality: Inferior materials lead to premature failure rates of 25-30% within the first year.
Skyrocketing Shipping Costs: Delays from distant suppliers add $1,200-2,500 per shipment amid global disruptions.
Inconsistent Service: OEM/ODM requests ignored, with lead times stretching to 12+ weeks.
Quality Variability: China's supply chain issues mean mismatched specs, causing 37% higher maintenance costs.
Compliance Risks: Non-CE/FDA certified products risk fines in the USA.

These issues spike downtime and budgets. Ready for a fix? Scroll to solutions.
