The Enduro Bearings 6904 LLB C3 is a premium stainless steel radial bearing designed for durability and exceptional performance in demanding cycling applications. 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.
Engineered 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.
Enduro 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.
What makes 440C stainless steel better than other stainless steels?
440C stainless steel offers the highest strength, hardness, and wear resistance among 440-series alloys, due to its high carbon content and specialized heat treatments. This ensures longer life and better corrosion resistance in wet or harsh environments.
Can these bearings be used in suspension pivots?
While these bearings can be used as pivot bearings, Enduro recommends the MAX-type version for suspension applications due to its enhanced design for that purpose.
