Difficult or Stiff Swing
Symptom: The excavator struggles to swing, the swing motor labors, or the machine swings unevenly.
Cause: Severe damage to the raceways or rolling elements, seized rolling elements, or severe corrosion that has "locked up" the bearing.
Seal Damage
Symptom: Visible grease leaking from the seals or dirt and debris being pulled into the bearing cavity. This is often a precursor to more severe internal damage.
Cause: Worn, torn, or hardened seals due to age, exposure to harsh chemicals, or physical damage.
