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 Sourcing Small Electric Motors Frustrates US Buyers

As a purchasing manager in the USA, you're under pressure to optimize supply chains amid rising costs. In 2026, 62% of industrial buyers report delays from unreliable suppliers (source: McKinsey Supply Chain Report 2025).

High Prices Eating ROI: Premium motors from US/EU brands cost 30-50% more, squeezing your margins without proportional performance gains.
Low Quality Leading to Failures: Cheap imports fail prematurely, causing 25% downtime in automation lines—your operations can't afford that.
Skyrocketing Shipping Costs: Post-2026 tariffs and logistics hikes add $5-15 per unit, turning bulk orders unprofitable.
Inconsistent Supply Chains: Competitors in China flood the market with subpar mini electric motors, lacking customization for your OEM needs.
Regulatory Headaches: Non-compliant motors risk FDA/CE rejection, delaying your projects by weeks.
No After-Sales Support: Generic suppliers vanish when issues arise, leaving you to handle returns alone.

These pain points hit hard: imagine 37% higher costs and frequent breakdowns derailing deadlines. Ready to fix this?
