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 Robotics Hardware Sourcing is Failing Your Operations

As a purchasing manager in the USA robotics sector, you're under pressure to deliver high-ROI assemblies. Yet, common hurdles persist.

High Prices Eating Margins: Premium robotics hardware from US/EU suppliers costs 40-60% more, squeezing your budget amid 2026 supply chain inflation.
Low Quality Leading to Failures: Inferior ball screws and linear guides cause 25% downtime in robotic arms, per IEEE Robotics reports.
Skyrocketing Shipping Costs: Cross-Pacific delays add $5K+ per shipment, with tariffs inflating landed costs by 15%.
Customization Delays: OEM/ODM requests take 12+ weeks, missing your production deadlines.
Unreliable Suppliers: China's supply chain volatility leads to stockouts, impacting 37% of US importers (Gartner 2025).
Compliance Nightmares: Missing CE/RoHS certs block FDA-regulated robotics in med-tech.

These issues compound, raising total ownership costs by 50%. Ready for a fix?
