Crafted with precision, this bearing measures 37mm x 49mm x 6.5mm and features a 45° contact angle, making it a perfect fit for high-quality bike headsets. The use of 440C stainless steel balls and races ensures exceptional resistance to corrosion, ideal for riders who frequently encounter wet or harsh environments.\u003c\/p\u003e\n\n\u003cp\u003eUnlike typical stainless steel bearings, Enduro employs 440C stainless steel, renowned for its high strength, hardness, and wear resistance. This material undergoes advanced heat and cryogenic treatments to enhance its mechanical properties, delivering long-lasting reliability. The bearing’s design includes dual-lip LLB seals paired with CRC Marine Grease, providing an additional layer of waterproof protection against sweat and environmental elements. This combination guarantees smooth steering and longevity, even under demanding conditions.\u003c\/p\u003e\n\n\u003cp\u003eEnduro Bearings' angular contact headset bearings are crafted to evenly distribute force across all balls, reducing friction and wear while maximizing lifespan. This model is widely recognized in the bicycle industry, also known as part number HD446K, and is compatible with many premium headset brands. Whether you’re a casual rider or a competitive cyclist, these bearings offer the perfect balance of strength and corrosion resistance to keep your bike’s steering precise and responsive.\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 conditions\u003c\/li\u003e\n  \u003cli\u003eEnsuring smooth and precise steering for improved handling\u003c\/li\u003e\n  \u003cli\u003eWithstanding rigorous use thanks to high-strength 440C stainless steel construction\u003c\/li\u003e\n  \u003cli\u003eOffering long service life with advanced heat-treated and cryogenic material processing\u003c\/li\u003e\n  \u003cli\u003eProtecting against sweat and environmental debris with dual-lip seals and marine-grade grease\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWhat It’s NOT Good For\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003eHeavy load applications requiring higher static load capacity than 917lbf\u003c\/li\u003e\n  \u003cli\u003eSituations where maximum hardness and load capacity of chromium steel (52100) are preferred\u003c\/li\u003e\n  \u003cli\u003eUse outside of bicycle headset and steering component applications\u003c\/li\u003e\n  \u003cli\u003eEnvironments with extreme impact or shock loads beyond normal cycling conditions\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 has the highest hardness, strength, and wear resistance among the 440-series alloys due to its higher carbon content and specialized heat treatments, making it ideal for corrosion resistance and long-lasting performance in demanding environments.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eCan I use these bearings in all bike headsets?\u003c\/strong\u003e\u003cbr\u003eThis bearing size is commonly compatible with many headset brands, often referred to as HD446K in the industry.
