Product Description
UNION CB640 Max Double Row LLU Bearings | High-Load Hub & Pivot PerformanceCategory: Spare PartsSubcategory: HubsUpgrade your ride´s reliability and performance with the UNION CB640 Max Double Row LLU Bearings. Specifically engineered for high-stress applications, these premium bearings are the ultimate spare part for your bicycle´s hubs and full-suspension pivots. Designed to handle significantly higher radial and axial loads than standard single-row bearings, they ensure smoother rotation, enhanced durability, and a longer service life for your most critical components. Whether you´re rebuilding a worn-out hub or upgrading for maximum strength, the CB640 is the professional´s choice for uncompromising performance.The Max designation signifies a full-complement design, meaning these bearings are packed with the maximum number of ball bearings possible by forgoing a traditional cage. This ball against ball construction dramatically increases the contact points, allowing for a substantial boost in load-bearing capacity. This makes the CB640 exceptionally well-suited for demanding disciplines like mountain biking, enduro, and e-biking, where components are subjected to intense and repeated impacts.Key Benefits:* Exceptional Load Capacity: The innovative double-row, full-complement (Max) design distributes forces across a greater number of ball bearings, providing superior resistance to both radial and lateral forces. This reduces flex and wear, making it ideal for high-torque rear hubs and critical suspension pivots.* Superior Protection Against the Elements: Featuring advanced LLU full-contact rubber seals on both sides, these bearings create a robust barrier against water, mud, dust, and grime. This tight seal ensures the internal grease stays clean and contaminant-free, preserving smooth operation even in the harshest riding conditions.* Unmatched Durability and Strength: Constructed with high-grade Chromium Molybdenum (CrMo) steel for both the inner/outer rings and the ball bearings, the CB640 is built to last. The balls are hardened to an impressive HRC 61-66 rating, offering exceptional resistance to deformation and wear over thousands of miles.* Long-Lasting, Smooth Operation: Each bearing is pre-lubricated from the factory with premium Multemp SRL grease by Kyodo Yushi. This high-performance lubricant is renowned for its excellent water resistance and stable viscosity across a wide temperature range, ensuring minimal friction and consistent performance from the very first rotation.* Precision Engineering for Smooth Performance: Manufactured to a precise ABEC-3 tolerance standard, these bearings guarantee minimal play and runout. This level of precision translates directly to a smoother-feeling ride, reduced vibration, and more efficient power transfer through your drivetrain and suspension system.Technical Specifications and Attributes:These high-performance Bearings are defined by their top-tier technical features, ensuring a perfect fit and function for demanding repairs and upgrades.* Model: CB640* Measure (Inner x Outer x Width): 17x28x9 mm* Rings Material: CrMo Steel* Balls Material: CrMo Steel * Cage Type: None (Full Complement / Ball Against Ball)* Sealing: Double-Sided Rubber LLU (Full Contact Seal)* Grease (Fat): Multemp SRL (by Kyodo Yushi)* Tolerance: ABEC-3When standard bearings fail to meet the demands of aggressive riding, the UNION CB640 Max Double Row LLU Bearings deliver the strength, sealing, and precision you need.
