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 Rack and Pinion Setup is Costing You Dearly

As a purchasing manager in the US manufacturing sector, you're facing skyrocketing operational costs in 2026. High prices from domestic suppliers, inconsistent quality from cheap imports, and brutal shipping fees are eroding your ROI.

High Prices: Traditional US suppliers charge 2-3x more for standard rack and pinion for sale – up to $150/meter vs. our $50/meter equivalent.
Low Quality: Inferior steel warps under load, causing 25% more machine failures per industry reports from AMT (Association for Manufacturing Technology).
High Shipping Costs: Fragmented supply chains add $500-2000 per order; delays average 8-12 weeks from competitors.
Poor Customization: Off-the-shelf parts don't fit your CNC or robotic arms, leading to redesigns and 15-20% waste.
Unreliable Delivery: Supply chain disruptions hit 37% of US firms in 2025 (per Deloitte), halting production lines.
Weak After-Sales: No local support means weeks of downtime for minor issues.

These issues compound: a single rack failure can cost $10,000 in lost production. Ready to fix this? Explore our solutions below.
