Precision Balls
High‑speed
steel balls

High‑precision high‑speed steel balls offer excellent fatigue resistance, even when operating at elevated temperatures, making them a preferred choice for demanding environments.

Manufacturing high‑precision
high‑speed steel balls for critical applications

Main applications:

  • M50 balls: intended for ball bearings and ball screws, mainly in the aerospace sector. The material is produced according to AMS 6491 (VIM‑VAR), and the heat treatment is NADCAP‑certified, ensuring compliance with aerospace quality standards.

  • M2, T15 and M62 (CPM® REX® 20) balls: used in X‑ray tubes where precision is essential. Our manufacturing process allows us to achieve Grade 3 quality and an excellent surface finish—two key requirements for this application.

PRECISION LEVEL: Grade 10 balls, Grade 100 balls, Grade 200 balls, Grade 500 balls
