Product Quality Inspection

Bearing Quality Inspection

In terms of bearing quality control, the company always adheres to the principle of “high requirements, strict control, and quality first”. The company has set up a quality testing center, with more than 50 quality inspection and testing instruments, such as metallographic microscope, roundness meter, wheel gallery, JD-18 universal length measuring instrument and so on.

Bearing quality inspection project

For each batch of products produced, we will first check the basic dimensions. The tools used for on-site testing are: caliper 0.02mm, micrometer 0.01mm, dial gauge 0.01mm, dial gauge 0.001mm, torsion spring table 0.001mm\0.002 Mm, fan-shaped table 0.01mm, etc.;

Samples are then taken from each batch and professional instruments are used for more detailed quality testing.
