A selection of Tungsten Carbide Checking Balls. Tungsten Carbide RC 65-68

  • Checking balls are precision balls used in various applications for dimensional checking, calibration, and verification of sizes and dimensions.
  • These balls are typically made of high-quality materials with tight tolerances to ensure accurate measurements.
  • Checking balls are often used in coordinate measuring machines (CMM) and other metrology equipment to verify the accuracy of machined parts and components.
  • Ball and shank are concentric within 5 microns (0.0002 in.) TIR.
  • Weld between ball and shank is designed so the ball will fall off if subject to unusually heavy lateral force, preventing set up and inspection errors that may occur because of a bent shaft.
