Detections of seal lip peeling and scratches

The lip part of seals is easy to peel off, so the LJ-V is used to inspect for this problem. Also, because the location where the peel started from is unknown, the bearing must be rotated to inspect its entire circumference. Due to the miniaturisation of bearings and the increase in the number of bearings produced, there are demands for both improved inspection takt time and improved inspection capability. The LJ-V Series boasts the highest speed in the world at 64000 profiles/s, which makes it possible to perform extremely fast processing. Also, because the LJ-V has 16 outputs, a variety of inspections can be performed—such as measurements of the overall height and shape of the seal and the surface runout of the inner and outer races—simultaneously with the lip peeling inspection.
