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 USA Manufacturers Struggle with Curved Gear Racks in 2026

As a purchasing manager in automation or robotics, you face mounting pressures: supply chain disruptions up 25% YoY (per Deloitte 2025 report), escalating tariffs, and inconsistent supplier quality. Here's what hits hardest:

High Prices: Standard racks cost $150+/meter, squeezing your ROI amid inflation.
Low Quality: Inferior steel warps under load, causing 15-20% failure rates in curved applications like robotic arms.
Skyrocketing Shipping Costs: Delays average 45 days from Asia, with fees hitting $5,000/container post-2025 port strikes.
Poor Customization: Off-the-shelf racks don't match your curved path radii (e.g., 500-2000mm), leading to redesigns.
Compliance Headaches: Missing RoHS/CE certs block USA imports, risking FDA/ISO audits.
Service Gaps: No OEM/ODM support means you're stuck iterating prototypes solo.

Scenario: Your CNC machine jams on curved tracks, halting production for 8 hours/day – that's $12,000 lost revenue weekly. Sound familiar?
