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.

The Hidden Costs of Inferior Linear Guides in Your Operations

As a purchasing manager in the US manufacturing sector, you're under pressure to cut costs while maintaining precision. But sourcing recirculating ball linear guides from unreliable suppliers leads to real headaches.

High Prices from Western Brands: Premium guides cost up to $150 per meter, squeezing your ROI without proportional benefits.
Low Quality from Cheap Imports: Subpar ball linear guides fail prematurely, causing 37% higher maintenance costs per a 2025 AMT report.
Excessive Shipping Delays & Costs: Weeks of wait time from Asia inflate logistics by 20-30%, disrupting production schedules.
Inconsistent Precision: Variations in preload and ball recirculation lead to vibrations, reducing machine accuracy by up to 0.05mm.
Lack of Customization: Off-the-shelf options don't fit OEM needs, forcing expensive modifications.
Poor After-Sales Support: No local compliance or quick replacements, risking FDA/CE non-conformance in regulated industries.

These issues compound: a single guide failure can halt a $50K CNC line for 48 hours. Ready to break the cycle?
