Stainless steel and chrome steel are normally corrosion-resistant, not easy to rust. However, improper storage or handling at high humidity, condensation environment will reduce bearing life.
How does the corrosion of bearings happen?
If the bearing is prolonged exposure to water can cause rust. With the passage of time can cause peeling and crack formation, which are premature bearing failures.
In addition, if the bearing is too loose or improper installated, contact corrosion will occur..
Bearing corrosion will reduce the machine performance and productivity, increasing the cost of operation.
Common raceway corrosions include, bearing contact corrosion, corrosion of the outer surface and the inner ring of holes.
How to prevent bearing corrosion?
Prevention is the main thing. Here are some methods which can prevent bearing corrosion
Use waterproof grease, it can form a protective barrier in the wet environment
Add some protective coatings, such as chrome, nickel, zinc
Adjust bearing, if it is suspected of contact corrosion
Try to use a different material, in extremely corrosive environment, you can use ceramic bearings for example.
