Fusing of the sliding layer
DESCRIPTION OF THE DAMAGE
- Material displacement and smearing visible in the sliding surface
- Accompanied by heat cracks and discolouration of the bearing shell

White fusion deposits are visible in the galvanic layer.
Possible causes
- Consequential damage due to increasing temperature development as a result of initial rubbing marks, seizure or edge wear
- Insufficient heat dissipation provided by the lubricant
Remedy
If overheating damage occurs, the bearing must be replaced and the causes investigated. In the event of consequential damage, the cause of the primary damage must be rectified. If no further damage to the bearing is visible, the lubricant circuit and the stress on the bearing must be checked.
