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 Wholesale Arc Linear Guides Are a Headache for US Buyers in 2026

In the fast-paced world of industrial manufacturing, arc linear guides – essential for curved path applications like robotic arms and packaging lines – come with escalating challenges. Here's what you're likely facing:

High Prices: Traditional suppliers add 25-40% markups, driving up your ROI timeline. Industry reports show US buyers pay 30% more than direct factory sourcing.
Low Quality & Failures: Inferior curved linear rails lead to 45% higher downtime in precision tasks, per McKinsey automation studies.
Skyrocketing Shipping Costs: Delays from Asia average 4-6 weeks, with costs hitting $500+ per pallet due to tariffs and logistics bottlenecks.
Limited Customization: Off-the-shelf options don't match your OEM needs for arc radius or load capacity.
Supply Chain Risks: Competitors' unreliable China's supply chains cause stockouts, disrupting your operations.
Compliance Hurdles: Navigating CE, RoHS, and USA import regs eats into your time.
