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 Core Challenges Sourcing Small Electric Motors in 2026

As a US operations manager, you're under pressure to optimize automation lines. But unreliable suppliers create headaches.

High Prices: Competitors charge 40-50% premiums for basic small DC electric motors, eroding your margins. Industry data shows average motor costs rose 25% in 2025 due to supply chain disruptions.
Low Quality: Cheap imports fail prematurely—60% downtime risk in high-load apps like robotics, per IEEE reports.
High Shipping Costs: Slow ocean freight from Asia adds $5-10K per order, delaying your production by weeks.
Inconsistent Performance: Motors overheat or lose torque in linear actuators, causing 37% efficiency loss in real-world tests.
Limited Customization: Off-the-shelf options don't fit OEM needs, forcing redesigns.
Poor After-Sales: No local support means weeks of downtime for repairs.

These issues cost US firms $2.5B annually in automation failures (McKinsey 2025). Ready for a fix?
