Question:

What are the different precision grades available for stainless steel balls?

Answer:

Stainless steel balls are available in several precision grades, which are determined by their dimensional accuracy and surface quality. The most common precision grades for stainless steel balls are G10, G16, G25, G40, G60, and G100. G10 represents the highest precision grade, indicating a diameter tolerance of ±0.000025 inches and a sphericity tolerance of 0.000012 inches. It also has a surface roughness of approximately 0.00001 inches. The next precision grade is G16, which has a slightly larger diameter tolerance of ±0.000039 inches and a sphericity tolerance of 0.00002 inches. Its surface roughness typically measures around 0.000015 inches. Another commonly used precision grade is G25, with a diameter tolerance of ±0.000049 inches and a sphericity tolerance of 0.000025 inches. The surface roughness for this grade is usually around 0.00002 inches. Moving on to G40, this grade has a larger diameter tolerance of ±0.000078 inches and a sphericity tolerance of 0.000039 inches. The surface roughness is typically around 0.000025 inches. G60, with a diameter tolerance of ±0.000118 inches and a sphericity tolerance of 0.000059 inches, comes next. The surface roughness for this grade is usually around 0.000032 inches. Lastly, G100 represents the lowest precision grade, with a diameter tolerance of ±0.000197 inches and a sphericity tolerance of 0.000099 inches. The surface roughness typically measures around 0.000039 inches. These precision grades offer different levels of dimensional accuracy and surface quality for stainless steel balls, catering to various industrial applications that have specific precision requirements.
