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 US Manufacturers Struggle with Miniature Linear Motors

As a purchasing manager in the USA, you're under pressure to optimize automation lines while cutting costs. But sourcing miniature linear motors often leads to frustration.

High Prices: Domestic options cost 2-3x more – averaging $150+ per unit vs. our $50-80 range. A 2025 McKinsey report notes US firms overpay by 37% on precision components.
Low Quality: Cheap imports fail prematurely, causing 25% downtime in robotics, per IEEE data. Vibration and heat lead to 40% rejection rates.
Skyrocketing Shipping Costs: Delays from Asia average 45 days + $20-50/unit freight. Supply chain disruptions hit 68% of US ops managers in 2025 (Gartner).
Inconsistent Quality Assurance: No OEM customization – forcing redesigns that eat 20% of your budget.
Slow Delivery: Competitors' lead times exceed 60 days, missing your Q1 deadlines.
Compliance Headaches: Non-CE/FCC certified motors risk FDA recalls in medical apps.

These issues inflate your ROI timeline from 6 to 18 months. Ready to fix this? Read on for our proven solution. Jump to specs →
