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.

Struggling with Miniature Linear Stage Sourcing? You're Not Alone

In 2026, USA operations managers face skyrocketing demands for compact precision motion in automation, medical devices, and semiconductors.

High Prices: Competitors charge 40-60% more for imported mini linear stages, eroding your ROI.
Low Quality: Cheap alternatives fail prematurely, causing 25% downtime in production lines per industry reports from SEMI.org.
High Shipping Costs: Delays from China suppliers add $500-2000 per unit in fees and weeks in transit.
Inconsistent Precision: Backlash and poor repeatability exceed 5μm, ruining micron-level applications.
No Customization: Off-the-shelf options don't fit OEM needs, forcing redesigns.
Supply Chain Risks: Geopolitical tensions disrupt deliveries, as seen in 2025 shortages.
