Hardness is a key factor in airsoft bearings longevity and resistance to wear and deformation. Higher hardness means better performance under stress and longer lifespan. Hybrid bearings with ceramic balls, such as the Modify - Bearing Set (7mm), offer a Vickers Hardness of 1550 compared to 730 for steel, resulting in much less wear and greater reliability at high speeds. All-steel bearings, like the Modify 8mm Steel Bearing Set, also provide strong hardness suitable for most applications. With a range of hardness levels available, users can choose the bearing that best suits their durability requirements.
