Quality Control Process
1
Incoming Material Inspection
Chemical composition analysis, hardness testing, and metallurgical structure verification of all raw steel materials.
2
In-Process Dimensional Inspection
Continuous monitoring of bore, OD, width, and raceway geometry using precision measuring instruments during production.
3
Surface & Roundness Measurement
Roundness, waviness, and surface roughness measurements on critical raceway and rolling element surfaces.
4
Final Audit & Testing
100% inspection for noise, vibration, radial clearance, and rotational accuracy before packaging and shipment.
Inspection Equipment
Roundness measuring machines
Surface roughness testers (Ra, Rz)
Hardness testers (Rockwell / Vickers)
Vibration & noise measuring instruments
Profile projectors and CMM
Bore gauges, micrometers, height gauges
