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 High-Cost, Low-Quality Miniature Linear Guides?

In 2026, USA manufacturers face intensified pressure from rising material costs and supply chain disruptions. Your operations demand reliable mini linear guides for compact robotics and medical devices, but competitors from China often fall short.

High Prices: Premium brands charge up to $150 per unit, eroding your ROI on high-volume automation projects.
Low Quality: Inferior small linear guides fail prematurely, causing 37% more downtime according to a 2025 McKinsey report on linear motion failures.
High Shipping Costs: Delays from overseas suppliers add 20-30% to landed costs, especially post-tariff hikes.
Limited Customization: Off-the-shelf options don't match your OEM needs for precision tolerances under 5 microns.
Unreliable Supply: Stockouts disrupt production lines, with 42% of managers reporting delays per IndustryWeek surveys.
Compliance Risks: Non-USA certified products risk FDA or RoHS violations in medical/semiconductor apps.
