QIBR - 691X Deep Groove Ball Bearing Quality Control

Dimension measurement: Multiple high-precision instruments are used to measure various dimensions of the bearing, with an accuracy of up to 0.001mm.

Rotation accuracy: A dial gauge measures minor surface flaws or deviations, with measurement accuracy reaching 0.001mm.

Hardness measurement: The surface hardness of the bearing is measured using a hardness tester, with an accuracy of ±0.5HRC.

Metallographic analysis: A professional metallographic microscope is used to analyze the internal metallographic structure of the metal.

Geometric tolerance: A profilometer is used to measure the geometric shape and relative position of the bearing.

Noise monitoring: A vibration meter monitors vibrations during operation, providing noise data with a noise vibration level not lower than Z3V3.

Raw material control: Steel and parts are sourced from ISO 14001-certified suppliers, ensuring product stability while promoting sustainable development.
