Seizure (Complete Lock-Up)
Cause: This is a catastrophic failure, typically the end stage of severe contamination, total lack of lubrication, or ignored progressive damage. The bearing welds itself together due to heat and friction.
Water, Mud, and Debris Ingestion
Cause: Damaged, worn, or degraded seals allow environmental contaminants to enter the bearing assembly. Water is particularly damaging as it causes rust, washes away grease, and drastically reduces lubricating effectiveness.
This 267-6788 slewing bearing is used for 365L excavator.
