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 Rotary Hydraulic Actuators Are Costing You Dearly

In 2026, US manufacturers report 42% downtime from subpar rotary hydraulic actuators, per IndustryWeek data. You're likely facing these pain points:

High Prices: Premium brands charge $2,500+ per unit, eroding your ROI amid inflation.
Low Quality: Frequent leaks and failures lead to 37% higher maintenance costs, halting production lines.
Skyrocketing Shipping Costs: Overseas delays add $1,200/unit in logistics from unreliable suppliers.
Inflexible Designs: Off-the-shelf options fail in custom automation, causing redesign expenses.
Slow Delivery: 12+ week lead times disrupt your supply chain timelines.
Compliance Risks: Non-CE/FDA certified units risk fines in regulated US markets.
