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 Roller Followers Are Failing Your Operations

As a purchasing manager in the USA manufacturing sector, you're under pressure to optimize ROI amid rising costs. High price from premium brands, low quality from cheap imports, and high shipping costs from distant suppliers plague your supply chain.

Pain Point 1: Frequent breakdowns – Inferior roller cam followers wear out 2x faster, causing 37% unplanned downtime per US industry reports (Source: McKinsey Manufacturing 2025).
Pain Point 2: Skyrocketing costs – Competitors charge 25-40% premiums without matching performance, eroding your margins.
Pain Point 3: Logistics delays – Shipping from Europe or Asia takes 6-8 weeks, halting production lines.
Pain Point 4: Inconsistent quality – China's supply chain variability leads to 22% defect rates in needle roller followers.
Pain Point 5: Limited customization – Off-the-shelf options fail to fit OEM/ODM needs for high-speed linear motion.

These issues cost USA firms $50B annually in lost productivity. Ready to fix them? Discover our solution below.
