Backgrounds:

The majority of bearing manufacturers use the traditional inspection method- hiring inspection workers to find surface defects. But this is tedious work that requires high strength and is very inefficient. Inspectors often miss inspection and misjudge due to fatigue. 

Detectable products:
CR, TR, SR, railway roller, wind power roller, piston pin, piston ring, rocker roller ring, etc.

Detectable types of defects:
crack, miss superfinishing, under superfinishing, notch, grinding mark, light scratch, spiral mark, padding mark inside dimple, missing material on chamfer, burr, corrosion, mixed material, chipping.
