Seizure or Complete Lock-Up:
Cause: This is a catastrophic failure, usually the end result of ignored earlier symptoms like noise and roughness. It occurs when wear or damage is so severe that the rolling elements can no longer move freely.
Water or Mud Ingestion:
Cause: Damaged or worn-out seals allow water, mud, and other contaminants to enter the bearing assembly. Water causes rust and corrosion, which accelerates wear and breaks down the grease's lubricating properties.
This 393-6547 slewing bearing is used for 328D excavator.
