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 Biggest Challenges with Wholesale HGR20 Linear Rails

As a purchasing manager in the USA manufacturing sector, you're under pressure to cut costs while maintaining precision in linear motion systems. But unreliable suppliers lead to headaches.

High Prices: Competitors charge up to $15 per meter for HGR20 rails, inflating your ROI timeline by 6 months.
Low Quality: Cheap imports fail prematurely, causing 25% machine downtime and $50K annual losses per production line (per IndustryWeek 2025 report).
High Shipping Costs: Slow ocean freight from Asia adds $2-3K per pallet and weeks of delay, disrupting your supply chain.
Inconsistent Specs: Rails that don't match HIWIN HGR20 standards lead to vibration and 15% accuracy loss in CNC applications.
No Customization: Standard lengths force excess waste and machining, hiking costs by 20%.
Poor After-Sales: No local support means you're stuck with defective batches.
