Enduro only uses 440C stainless steel balls and strives for long life and superior corrosion resistance in applications and environments that may be less than ideal. 440C has the highest strength, hardness, and wear resistance of all standard high-carbon 440 series stainless alloys. As expected, it is also the most expensive of the 440 series alloys and requires multiple rounds of heat treatment and cryogenic treatment to achieve its superior mechanical properties. Although stainless steel has 20% less load capacity and is slightly softer than our standard 52100 chrome steel used in most of our bearings, stainless steel is an excellent alternative for use in wet conditions, if you wash your bike frequently, or where sweat can be an issue. Enduro Bearings also uses LLB type seals and CRC Marine grease in these bearings to be extra water resistant against the elements. Enduro 440C stainless headset bearings are the same bearings found in many popular headset brands, including those with 110-year warranties.
