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 U.S. Buyers Struggle with Super Precision Ball Bearings

In 2026, with supply chain disruptions persisting, 68% of U.S. manufacturing firms report bearing failures causing over $50K annual downtime (per Deloitte Industrial Report). Your team faces these core pain points:

High Prices: Premium brands charge 2-3x more for ABEC-7 equivalents, eroding your ROI.
Low Quality: Off-spec tolerances lead to vibration, heat buildup, and spindle crashes in CNC machines.
High Shipping Costs: Delays from Europe/Asia average 8-12 weeks, inflating logistics by 25%.
Inconsistent Supply: China's fragmented chains mean batch variations, risking production halts.
Limited Customization: No OEM/ODM for specific spindle speeds over 20,000 RPM.
Poor After-Sales: No U.S.-friendly support for failures in high-precision apps like robotics.

These issues compound: a single bearing failure can halt a $1M CNC line for days. Ready to fix this? Discover our solution below.
