Grades - DIN 5401 2002

Product catalog summary
Overview: This document outlines the specifications for spherical balls as per the DIN 5401 standard from Germany, dated 1st August 2002. It provides detailed information on the grades, nominal ball diameters, and various allowances and deviations.
Specifications:
  • Grades: The document lists multiple grades (G3, G5, G10, etc.) with specific nominal ball diameters and associated tolerances.
  • Nominal Ball Diameter (Dw): The standard specifies the nominal diameter for each grade.
  • Gauge Allowance (VDws): Maximum allowable variation in the single diameter of a ball.
  • Surface Roughness (Ra): Maximum allowable surface roughness for each grade.
  • Deviation from Ball Gauge (∆S): Specifies the allowable deviation from the nominal gauge.
  • Deviation from Spherical Form (tDw): Maximum allowable deviation from a perfect spherical form.
Procedures and Norms:
  • Sorting Gauges (IG): Guidelines for sorting balls based on their gauges.
  • Mean Allowances: Each grade has specified mean allowances for deviations, ensuring consistency in manufacturing.
Key Data from Tables:
  • The table provides detailed measurements for each grade, including nominal diameters, maximum deviations, and surface roughness values.
  • Grades range from G3 to G700, with increasing tolerances and deviations as the grade number increases.
Critical Information:
  • Each grade has specific requirements for diameter variation, surface roughness, and spherical form deviation, which are crucial for quality control in manufacturing processes.
  • Understanding these specifications is essential for ensuring the precision and reliability of spherical components in various applications.
