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 Top Challenges You're Facing with Small Rack and Pinion Systems

As a purchasing manager or technical director in the USA, you know small rack and pinion components are critical for compact linear motion in robotics, automation, and precision machinery. But sourcing them often leads to frustration.

High Prices: Imported small rack and pinion from competitors average 40-50% higher due to markups and tariffs, squeezing your ROI.
Low Quality & Failures: Cheap alternatives wear out 2x faster, causing 25% unplanned downtime per industry reports from McKinsey on manufacturing reliability.
Skyrocketing Shipping Costs: Delays from overseas suppliers add $500-2000 per order, especially post-2026 supply chain disruptions.
Lack of Customization: Off-the-shelf miniature rack and pinion doesn't fit your OEM needs, forcing redesigns.
Compliance Headaches: Ensuring RoHS, CE, and USA standards compliance without proper certs risks fines.
Slow Lead Times: Waiting 8-12 weeks kills project timelines in fast-paced industries like automation.

These issues compound: a single failure can cost $10,000+ in lost production. Ready for a better option? Keep reading.
