CH 6902 LLB - ABEC-5, Ceramic-Hybrid, Radial Bearing (C3 Clearance) - 15mm x 28mm x 7mm

Upgrade your bicycle's performance with the Enduro Ceramic Hybrid 6902 LLB Sealed Cartridge Bearing, a component engineered for durability, precision, and smooth operation. Crafted specifically for demanding enduro and mountain biking applications, this bearing offers exceptional performance under rigorous riding conditions. Materials & Engineering Excellence Constructed with Grade 5 Silicon Nitride (Si3N4) ceramic balls, the Enduro Hybrid 6902 delivers superior hardness, reduced weight, and enhanced wear resistance compared to traditional steel bearings. The ceramic balls provide lower friction, increased speed capabilities, and improved thermal stability for a more responsive ride. The races are made from cryogenically treated 52100 chromium steel, which undergoes three specialized cryogenic processes to optimize hardness, fatigue life, and resistance to deformation. Advanced Components & Technology Featuring a light-contact, two-lip LLB Nitrile Butadiene Rubber (NBR) seal, this bearing ensures minimal friction while maintaining effective dust and moisture exclusion. The seal rides smoothly within a groove, providing low-contact sealing performance-ideal for mountain biking environments where dirt, mud, and water can impact bearing longevity. The nylon and graphite retainer further reduces weight and friction, contributing to a more efficient and durable bearing assembly. Designed for Performance & Versatility With precise ABEC 5 tolerances, the Enduro Ceramic Hybrid bearing guarantees optimal alignment, reduced vibrations, and prolonged service life. Its compact dimensions (15mm inner diameter, 28mm outer diameter, and 7mm width) make it suitable for a variety of critical bike components, including hubs, suspensions, and cranksets. Whether for upgrading your mountain bike or enhancing your downhill setup, these bearings deliver consistent, high-performance results.
