Enduro Bearings 3802 W LLB - CXD - 15x24x10 is a top choice for cyclists seeking durability and performance. This bearing features a unique XD-15 Ceramic-Hybrid design, combining corrosion-resistant nitrogen steel races with Grade 3 Silicon Nitride ceramic balls. This combination ensures a high-performance setup that stands the test of time. The deep-groove raceways in the Enduro Bearings 3802 W LLB - CXD - 15x24x10 allow for larger ceramic balls, enhancing contact area and boosting both performance and longevity. The dual-lip labyrinth (LLB) seals offer excellent protection against the elements, while the 90% fill Kluber NBU52 grease ensures smooth operation and resistance to washout. One standout feature of the XD-15 ceramic-hybrid bearings is their ability to improve with use. As they wear in, the ceramic balls polish the races, making them even smoother over time. This means that while other bearings may slow down, the Enduro XD-15 bearings continue to get better, offering a lifetime of reliable performance. We back this with an unlimited lifetime warranty on both the bearing and race. Primarily used by White Industries in their rear hubs, this bearing's extra-wide double-row design reduces axle flex, fitting perfectly in the space of two 6802 single-row bearings. Enduro Bearings offers a range of materials, including High-Carbon Chromium Steel, 440C Stainless Steel, Ceramic-Hybrid, and XD-15 with Ceramic or Stainless Balls. All bearings are designed with deep groove races to accommodate the largest balls possible, and feature dual-lip seals for maximum protection. Static Load: 520 lbf, 2.31 Kn Weight: 10.5g
