Every batch of GCr15 bearing steel is checked for chemical composition and metallographic structure before production begins.
In-process checks on turning, heat treatment and grinding keep every dimension within tolerance.
Micrometers, bore gauges and roundness testers verify inner/outer diameter, width and runout.
Rockwell hardness testers confirm proper heat treatment of rings and rolling elements.
Vibration analyzers grade every bearing for noise level before assembly sign-off.
Appearance, marking, clearance and rotation are verified on finished bearings.
