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 Motor Shafting Challenges in 2026 USA Manufacturing

As a purchasing manager or technical director, you're under pressure to optimize supply chains amid rising costs and supply disruptions. Motor shafting failures amplify these issues.

High Prices from Local Suppliers: USA-sourced shafts cost 25-40% more, squeezing your ROI without superior performance.
Low Quality & Frequent Failures: Inferior materials lead to wear rates 3x higher, causing 37% unplanned downtime per industry reports from McKinsey 2025.
Skyrocketing Shipping Costs: Global logistics volatility adds 15-20% to landed costs, especially post-2026 tariffs.
Customization Delays: OEM/ODM requests take 8-12 weeks from competitors, halting your production lines.
Quality Inconsistencies: Variable tolerances cause vibration and misalignment in high-speed motors.
Regulatory Compliance Headaches: Ensuring RoHS, REACH for USA imports eats into your time.

Imagine slashing these pains—keep reading for proven fixes.

Technical Deep Dive (1/3 Article Focus): Our motor shafting excels in dynamic load applications. For instance, at 10,000 RPM, our SCM440 shafts maintain 0.001mm radial runout, per 100-hour endurance tests. Material microstructure analysis shows uniform martensite post-quenching, boosting fatigue strength to 600MPa. In linear motion pairings (e.g., with our ball screws), preload adjustments ensure zero backlash, ideal for high-precision motor shafting in robotics.

Performance data: Torque capacity scales with diameter—Ø20mm shaft handles 150Nm continuously. Heat dissipation modeling (FEA via SolidWorks) confirms <20°C rise under full load, preventing thermal expansion issues.
