CXD 6903 LLB Radial Bearing XD15 Ceramic-Hybrid, ABEC-5, with LLB Seals (CN Clearance) 17mm x 30mm x 7mm
The Ultimate Upgrade - Exclusive to Enduro Bearings, our XD15 Ceramic-Hybrid bearings combine corrosion-resistant, cryogenically treated nitrogen steel races with Grade 5 Silicon Nitride ceramic balls in a proprietary process that results in the ultimate high-performance bearing setup.
The deep groove design of the races allows for the use of maximum size Grade 5 Silicon Nitride ceramic balls for greater contact area, improved performance, and extended longevity. Dual-lip labyrinth (LLB) seals protect from dirt and contain 90% Kluber NBU52 grease, which glides more smoothly over time and is highly wear-resistant.
The most impressive feature of XD15 Ceramic-Hybrid bearings is that, unlike other bearings, they improve with time and use. As the bearings wear in, the ceramic balls make the XD15 run even smoother. So, compared to other ceramic hybrid bearings on the market that boast speed and power advantages from day one, Enduro XD15 bearings not only offer the same initial advantages but will also become faster and smoother with time and use, while other ceramic hybrid options will only become slower. We are so confident in the performance of XD15 ceramic hybrid bearings that they come with a lifetime warranty against wear and corrosion.
This bearing is mainly used by Industry Nine in their rear hubs. Its extra-wide double-row design significantly reduces flex in the rear hub axle, while occupying the same space as two single-row 6802 bearings.
Enduro bearings are available in high-carbon chromium steel, 440C stainless steel, ceramic hybrid, and XD15 with ceramic or stainless steel balls. Our bearings are always designed with the deepest possible race grooves to accommodate the largest possible balls and feature dual-lip seals that glide in a micro-groove, creating a complete labyrinth to provide superior protection against water and dirt.
