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 Your Current Housed Bearings Are Costing You More Than You Think

As a purchasing manager in the USA manufacturing sector, you're under pressure to cut costs while maintaining uptime. But subpar housed bearings (also known as pillow block bearings) lead to frequent failures.

High Prices from Western Suppliers: Premium brands charge 2-3x more, eroding your ROI—industry data shows average bearing costs up 25% in 2025.
Low Quality & Frequent Failures: Cheap imports fail prematurely, causing 40% unplanned downtime per McKinsey reports.
Skyrocketing Shipping Costs: Delays from overseas without optimized logistics add 15-20% to total landed costs.
Inconsistent Quality from China's Supply Chain: Varying standards lead to misalignment in linear motion systems.
Limited Customization: Off-the-shelf units don't fit OEM needs, forcing expensive modifications.
Poor After-Sales Support: No quick replacements mean weeks of production halts.
