Enduro Bearings manufactures bearings using 440C Stainless Steel balls and races. 440C is superior to the more commonly used 440A or 440B that other bearing manufacturers use interested in saving money. 440C stainless steel alloy has a higher Carbon content giving it maximum hardness and corrosion resistance after heat treatment and cryogenic treatment. 440C material achieves the highest corrosion and wear resistance in applications and environments where critical. Depending on the application, they are designed to ABEC-3 or ABEC-5 tolerances. While stainless steel is not as hard as bearing steel, Enduro uses only the best 440C Stainless and processes to bring about superior results and longevity, especially compared to other bearing manufacturers using cheaper materials.
When the rain won’t go away, and your bicycle seems more often to be used as a boat rather than a bicycle, you may want to consider 440C stainless steel bearings. While not quite as hard as chromium bearing steel, 440C stainless steel is a good alternative in constant wet conditions, or where sweat and sticky drinks become a problem with components such as headset bearings and Bottom Brackets. In fact, Enduro Stainless Steel bearings have become so successful we are now one of the largest suppliers to premium component makers interested in having no warranty problems and the best performance for their customers. Enduro Bearings uses LLB type seals and CRC Marine Grease in the 440C Stainless Steel bearings to additionally water proof against the elements.
