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 Linear Bearings in 2026 USA Manufacturing

As a purchasing manager in the USA, you're under pressure to cut costs while maintaining precision in automation lines. High prices from competitors erode your ROI, low-quality imports fail prematurely, and shipping delays from overseas disrupt schedules.

High Prices: Premium brands charge up to $150 per unit, squeezing margins in competitive bids.
Low Quality: Inferior bearings seize under load, causing 25% unplanned downtime per industry reports from McKinsey 2025.
High Shipping Costs: Standard ocean freight adds $20-50/unit from Asia, with 45-day lead times.
Inconsistent Performance: Variations in tolerance lead to vibration and wear in CNC machines.
Limited Customization: Off-the-shelf options don't fit OEM designs for robotics or packaging lines.
Supply Chain Risks: Geopolitical tensions inflate costs by 15-20% annually.

These issues compound, leading to 37% higher total ownership costs. Ready to solve them? Discover our solution below.
