This CMH Box was scraped due to bearing failure with resulted in the shaft ripping up the box end, center  plates & the shaft it self rendering it useless.

A closer look at the damage of the bearing failure.

This is a re-conditioned CMH Wheel assembly with no standard sealing arrangement except for the bearing seal itself be it 6314 2RS.

No standard sealing arrangement as can be seen on this photograph. Leaving a clear space between the wheel and box end.
