Product Description

Bearing Failure Modes:

Excavator bearings can experience different failure modes, including fatigue failure, wear, brinelling (indentations on raceways), corrosion, and damage from external impacts.

Fatigue failure occurs due to repeated loading and unloading cycles, leading to the development of cracks and eventual bearing failure.

Wear can result from insufficient lubrication, contamination, or abrasive particles in the operating environment, causing surface damage to the bearing components.

Brinelling occurs when excessive loads or improper handling cause indentations on the bearing raceways, reducing performance and potentially leading to premature failure.

Corrosion can occur in corrosive environments or due to inadequate sealing, leading to damage and decreased bearing lifespan.

External impacts such as shocks or overloads can cause immediate bearing failure or accelerate fatigue damage.
