Case Study
Impact Crusher
Bearing 22236
Elevated Radial Vibrations were experienced in Pulley NDE Bearing.
Horizontal was 12mm/sec(1x) while Vertical was 4.5mm/sec. (3x dominant).
Upon inspection marking was done with white marker between inner race and shaft to confirm the looseness. On the next visit, the mark was clearly moved. Upon dismantling the shaft, it was heavily worn out and after shaft rebuilding see how 3x was dropped.
