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 Core Challenges with Traditional Roller Rails

In the demanding world of US industrial manufacturing, sourcing reliable roller rail linear guides isn't straightforward. Corporate purchasing managers like you face mounting pressures in 2026.

High Prices Eating into ROI: Premium brands charge up to $150 per meter, squeezing your budgets by 25-40% compared to optimized supply chains.
Low Quality Leading to Failures: Inferior linear roller rail systems from low-tier suppliers fail under heavy loads, causing 37% more downtime according to IndustryWeek reports.
High Shipping Costs from Overseas: Delays from Asia-Europe-US routes add $500-2000 per shipment, with lead times stretching 8-12 weeks.
Inconsistent Supply Chain: Competitors reliant on fragmented Chinese suppliers deliver mismatched specs, risking 15% scrap rates.
Lack of Customization: Off-the-shelf roller rails don't fit your CNC machines or robotic arms perfectly, leading to 20% efficiency loss.
Poor After-Sales Support: No local compliance or quick replacements, violating US standards like RoHS and FCC.

These pain points aren't just numbers—they halt production lines and erode profits. Discover how YIDI Motion solves them below.
