What are the forms of bearing damage?

Bearing damage can occur due to various reasons, and there are several forms of bearing damage. Here are some common types:

1.Abrasive Wear:

Occurs when foreign particles, such as dirt or debris, come into contact with the bearing surfaces, leading to the removal of material from those surfaces.

2.Adhesive Wear:

Caused by the metal-to-metal contact between the bearing surfaces, resulting in the transfer of material from one surface to another.


Chemical reactions between the bearing material and its environment can lead to corrosion. This can weaken the bearing material and result in surface damage.


Repeated cyclic loading and unloading can cause fatigue in bearing materials, leading to the development of cracks and eventual failure.


Excessive friction or insufficient lubrication can cause overheating, leading to thermal damage and degradation of the bearing material.

6.False Brinelling:

Microscopic wear caused by small oscillations or vibrations in the bearing assembly, which can result in indentations on the raceways.

7.Electrical Pitting:

Electric currents passing through the bearing can lead to damage known as electrical pitting, where small craters or spots develop on the bearing surfaces.

8.Plastic Deformation:

High loads or shock loads can cause plastic deformation in the bearing material, leading to permanent changes in shape.


The presence of contaminants such as water, dust, or chemicals in the lubricant or operating environment can lead to various forms of damage.

10.Cavitation Erosion:

Common in rolling element bearings, cavitation erosion occurs when bubbles form and collapse within the lubricant, causing localized damage to the bearing surfaces.


Large, visible indentations on the bearing surfaces caused by heavy loads or impact.

12.Circumferential Cracks:

Radial or circumferential cracks in the bearing races or rolling elements, often resulting from excessive loading or improper mounting.

13.Lubrication Issues:

Inadequate or improper lubrication can lead to various problems, including increased friction, overheating, and accelerated wear.
