ENDURO BEARINGS Cxd 688 llb - xd-15 ceramic (radial) - 8x16x5

Upgrade your cycling performance with the Enduro Bearings XD-15 Ceramic-Hybrid radial bearing, designed for ultimate durability and smooth operation. Featuring corrosion-proof, cryogenically treated nitrogen steel races combined with high-grade Silicon Nitride Grade 5 ceramic balls, this bearing delivers exceptional high-performance results. Its deep-groove raceways accommodate larger ceramic balls for increased contact area, boosting performance and longevity. Dual-lip labyrinth (LLB) seals protect against dirt and water, while the Kluber NBU52 grease ensures smoothness over time and resists washout. Unlike other bearings, XD-15 bearings improve with use—ceramic balls wear in the races, making them even smoother. They offer initial speed and power advantages, which enhance over time, unlike competitors that slow down. Backed by a limited lifetime warranty against wear and corrosion, this bearing is ideal for lightweight hubs, pedals, derailleur pulleys, and some full suspension components. Available in high-carbon chromium steel, 440C stainless steel, ceramic-hybrid, and XD-15 variants with ceramic or stainless steel balls. Engineered with deep groove races and dual-lip seals in a full labyrinth design for superior element protection. Static load: 162 lbf / 0.72 kN | Weight: 3.1 g
