Dimension measurement: Various high-precision instruments are used to measure multiple dimensions of the bearings, achieving a maximum accuracy of 0.001mm.

Rotation accuracy: A dial gauge is employed to measure small defects or deviations on the bearing surface, with measurement accuracy reaching 0.001mm.

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

Metallographic analysis: Professional metallographic microscopes are used to analyze the internal metallographic structure of the metal.

Geometric tolerance: A profile projector is used to measure the geometric shape and relative position of the bearings.

Noise monitoring: Vibration monitors are utilized to track the vibration conditions during operation, providing noise data.

Raw material control: Steel and components are sourced from suppliers with ISO 14001 certification, ensuring product stability while promoting sustainable development.
