PRECISION LEVEL

The precision level of steel balls is typically measured in terms of their dimensional accuracy and surface finish. The international standard used to specify the precision level of steel balls is ISO 3290.

ISO 3290 provides a classification system for steel balls based on their dimensional tolerances. The standard defines several grades, ranging from G10 to G1000, with G10 being the highest precision level. The G10 grade indicates that the diameter of the ball has a tolerance of ±0.25 micrometers.

Here is a breakdown of the ISO 3290 grades and their corresponding dimensional tolerances:

G10: ±0.25 micrometers
G16: ±0.4 micrometers
G25: ±0.5 micrometers
G40: ±0.8 micrometers
G60: ±1.2 micrometers
G100: ±2.5 micrometers
G200: ±5.0 micrometers
G500: ±12.5 micrometers
G1000: ±25.0 micrometers

It's worth noting that higher precision levels require tighter dimensional tolerances, resulting in more accurate and consistent ball sizes. This precision is important in applications like bearings, valves, measurement instruments, and precision machinery where the balls need to fit precisely and provide reliable performance.
