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.

Your Biggest Challenges with Cheap Ball Screws

As a purchasing manager in the USA manufacturing sector, you're under pressure to cut costs without sacrificing machine uptime. Here's what you're facing:

High Prices Eating into Margins: Premium brands charge $200+ per meter for ball screws, forcing you to overpay by 50-70% compared to market averages.
Low-Quality Imports Failing Prematurely: Cheap knockoffs from unreliable suppliers lead to backlash errors up to 0.05mm, causing 25% more downtime per IndustryWeek reports.
Skyrocketing Shipping Costs: Overseas delays add $50-100 per unit in freight, plus customs headaches for USA-bound linear motion parts.
Inconsistent Quality & No Customization: Off-the-shelf options don't match your CNC router or robotic arm specs, leading to redesigns and lost productivity.
Long Lead Times Disrupting Production: Waiting 8-12 weeks for delivery means stalled assembly lines and missed deadlines.
Lack of After-Sales Support: No local compliance (CE, RoHS) or warranties, risking FDA/ISO audits in regulated industries.

These issues result in 37% higher overall costs per ball screw assembly, per McKinsey supply chain analysis.
