Not all stainless steel is of the same quality. Easybikeparts sets itself apart by using 440C stainless steel for both the balls and races in its bearings, an alloy known for its durability and exceptional resistance to corrosion, making it perfect for tough applications and harsh environments. Recognised for its outstanding strength, hardness, and wear resistance, 440C stainless steel has a high carbon content. This makes it the priciest of the 440-series stainless alloys, but it justifies the cost through its advanced mechanical properties, which are developed via comprehensive heat treatments and cryogenic processes.

Despite stainless steel bearings having a 20% lower load capacity and being slightly softer than Easybikeparts's standard steel bearings, they are superior for use in moist environments, frequent washing conditions, or areas where sweat exposure is likely. These bearings are further fortified against the elements with LLB type seals and Mobil grease.
