types of vibrating screen bearing failures

Bearing failures and their causes

The life of a rolling bearing is de-fined as the number of revolutions the bearing can perform before incipient flaking occurs. This does not mean to say that the bearing cannot be used after then. Flaking is a relatively long, drawn-out process and makes its pres-ence known by increasing noise and vibration levels in the bearing. There-
