Crafted from high-quality 440C stainless steel, this bearing features precise dimensions of 20mm x 37mm x 9mm, making it ideal for front hub use and pivot points. Its C3 clearance ensures smooth rotation and reduced friction under load, while the dual-lip seals and Mobil XHP 222 high-pressure waterproof grease provide excellent protection against water and dirt, extending the bearing’s lifespan even in harsh conditions.\u003c\/p\u003e\n\n\u003cp\u003eEngineered with 440C stainless steel balls and races, the 6904 LLB C3 offers superior corrosion resistance and wear performance compared to standard stainless steel alloys. This material choice guarantees strength and hardness, essential for maintaining reliable function during frequent exposure to moisture, sweat, and other environmental factors. Unlike typical stainless steel bearings, Enduro’s 440C series undergoes multiple heat and cryogenic treatments to enhance mechanical properties, making it a top choice for cyclists who demand both longevity and smooth operation.\u003c\/p\u003e\n\n\u003cp\u003eEnduro Bearings are known for their innovative design, incorporating deep groove races to accommodate larger balls and maximize load capacity. The labyrinth-style sealing system ensures dirt and moisture stay out, significantly reducing maintenance needs. With a static load rating of 661lbf \/ 2.94kN, this bearing balances strength and lightweight construction at just 37.2g, making it effective for a wide range of cycling components including bottom brackets, hub spares, and transmissions.\u003c\/p\u003e\n\n\u003ch3\u003eWhat It’s Good For\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003eProviding reliable, smooth rotation in front hubs and pivot points.\u003c\/li\u003e\n  \u003cli\u003eWithstanding exposure to water, dirt, and sweat due to superior corrosion resistance.\u003c\/li\u003e\n  \u003cli\u003eEnhancing performance in bottom brackets, hub spares, and transmission components.\u003c\/li\u003e\n  \u003cli\u003eReducing maintenance needs with durable dual-lip seals and waterproof grease.\u003c\/li\u003e\n  \u003cli\u003eOffering long-lasting durability thanks to 440C stainless steel and advanced heat treatments.\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-duty suspension applications better suited for MAX-type bearings.\u003c\/li\u003e\n  \u003cli\u003eEnvironments requiring higher load capacity than the stainless steel series can provide.\u003c\/li\u003e\n  \u003cli\u003eSituations where standard chromium steel bearings’ higher hardness is necessary.\u003c\/li\u003e\n  \u003cli\u003eUse in components incompatible with 9mm width bearings.\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?\u003c\/strong\u003e\u003cbr\u003e440C stainless steel offers the highest strength, hardness, and wear resistance among 440-series alloys, due to its high carbon content and specialized heat treatments.
