Crafted from 440C stainless steel, this bearing offers exceptional corrosion resistance, making it ideal for demanding environments where moisture and sweat are concerns. Its dimensions of 50x62x8 mm and 36 x 45 degrees contact angle make it a perfect fit for high-performance steering systems, including those specified for Giant Reign e+ series bikes.\u003c\/p\u003e\n\n\u003cp\u003eUnlike standard stainless steel, the 440C alloy used in these bearings has the highest strength, hardness, and wear resistance within the 440-series stainless steels. Achieving these superior mechanical properties involves meticulous heat and cryogenic treatments. Enduro Bearings complement this robust material with LLB type seals and CRC Marine Grease, ensuring reliable waterproofing and long-lasting performance. This combination provides peace of mind for riders who frequently wash their bikes or ride in wet conditions.\u003c\/p\u003e\n\n\u003cp\u003eDesigned with the largest possible balls and dual lip seals riding in a micro-groove, these angular contact bearings spread forces evenly across all balls, reducing pressure and wear. Filled to 90% with high-pressure waterproof grease, they guarantee consistent lubrication and protection against the elements. Enduro’s 440C stainless steel headset bearings are trusted by many top headset brands and come with an impressive reputation for longevity and reliability.\u003c\/p\u003e\n\n\u003ch3\u003eWhat It’s Good For\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003eProviding superior corrosion resistance in wet or humid environments\u003c\/li\u003e\n  \u003cli\u003eEnsuring smooth and precise steering through angular contact design\u003c\/li\u003e\n  \u003cli\u003eWithstanding heavy static loads up to 935lbf \/ 4.15kN\u003c\/li\u003e\n  \u003cli\u003eOffering long-lasting durability with high-quality 440C stainless steel construction\u003c\/li\u003e\n  \u003cli\u003eMaintaining optimal lubrication thanks to 90% filled high-pressure waterproof grease\u003c\/li\u003e\n  \u003cli\u003eProtecting against sweat and environmental elements with advanced dual lip seals\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWhat It’s NOT Good For\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003eApplications requiring the highest possible load capacity beyond stainless steel limits\u003c\/li\u003e\n  \u003cli\u003eEnvironments where pure chromium steel bearings are preferred for maximum hardness\u003c\/li\u003e\n  \u003cli\u003eUses where budget constraints favor less expensive bearing options\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eWhat makes 440C stainless steel better than other stainless steels for bearings?\u003c\/strong\u003e\u003cbr\u003e440C stainless steel combines high carbon content with advanced heat treatments, resulting in superior hardness, strength, and wear resistance compared to other 440-series alloys.
