Enduro Bearings manufactures some series of bearings using 440C stainless steel balls and races. This material provides maximum corrosion resistance in applications and environments where critical. Depending on the application, they are designed to ABEC-3 or ABEC-5 tolerances. Stainless steel has 20% less load capacity than the 52100 chromium steel, used in most of our bearings, but with far superior corrosion resistance. When the rain won’t go away, and your bicycle is more often used as a boat rather than a land craft, you may want to consider 440C stainless steel bearings. While a little softer than chromium bearing steel, 440C stainless steel is a good alternative in constant wet conditions, or where sweat becomes a problem such as headset bearings. Enduro Bearings uses LLB type seals and CRC Marine Grease in these bearings to additionally water proof against the elements.
