FAQ1: How does stainless steel prevent bearing rust and corrosion?
Stainless steel prevents rust and corrosion primarily through the formation of a passive chromium oxide layer on its surface. Here’s a more detailed explanation:
Chromium Content: Stainless steel contains a minimum of 10.5% chromium. For bearing grades like AISI 440C, the chromium content is typically 16-18%.
Passive Layer Formation: When chromium is exposed to oxygen (either in the air or water), it rapidly reacts to form a very thin, stable, and invisible layer of chromium oxide (Cr2O3) on the surface. This layer is called the “passive layer” or “passive film.”
Protective Barrier: This passive layer acts as an extremely effective barrier that prevents further oxidation (rusting) of the iron atoms within the steel. It essentially seals the surface from the corrosive environment.
Self-Healing: A remarkable property of this passive layer is its self-healing capability. If the surface is scratched or damaged, exposing fresh metal to oxygen, the chromium reacts almost instantaneously to reform the passive layer, maintaining its protective integrity.
Corrosion Resistance: This passive layer is highly resistant to many corrosive agents, including water, humidity, and mild acids/alkalis. The higher the chromium content (and sometimes other alloying elements like molybdenum), the more robust and resistant the passive layer becomes to more aggressive environments.

FAQ2: Difference between SS626ZZ and 626ZZ chrome steel bearings?
The key difference between SS626ZZ and 626ZZ (without the ‘S’ or ‘SS’ prefix) lies solely in the material composition of their rings and rolling elements, which then dictates their performance characteristics.
SS626ZZ is for applications where corrosion resistance and hygiene are critical, even if it means a slight compromise in load capacity and higher cost.
626ZZ is the standard workhorse bearing for general applications where high load capacity, durability, and cost-effectiveness are priorities, and the environment is dry and non-corrosive.
