CXD 6903 LLB – XD-15 Ceramic-Hybrid, ABEC-5, Radial Bearing (CN clearance) – 17mm x 30mm x 7mm –
The ultimate upgrade
An Enduro Bearings exclusive, our XD-15 Ceramic-Hybrid bearings combine corrosion-proof, cryogenically treated nitrogen steel races with Silicon Nitride Grade 3 ceramic balls in a proprietary process that results in the ultimate high performance bearing setup. The deep-groove design raceways allow for maximum sized Grade 3 Silicon Nitride ceramic balls for for increased contact area and improved performance and longevity. Dual-lip labyrinth (LLB) seals protect from the elements, and contain the 90% fill Kluber NBU52 grease that runs smoother with time and is highly resistant to being washed out.
The most impressive feature of XD-15 ceramic-hybrid bearings is, unlike other bearings, they only get better with time and use. As the bearings wear-in, the super-hard ceramic balls actually make the XD-15 races even smoother. So, when compared to other ceramic-hybrid bearings on the market that claim speed and power advantages on day one, Enduro XD-15 bearings not only provide the same initial advantages on day one, but will become faster and smoother with time and use, while the other ceramic-hybrid options will only get slower. We are so confident in the performance of XD-15 Ceramic-Hybrid bearings that they carry a limited lifetime warranty against wear and corrosion.
This size bearing is used primarily in hubs.
The Enduro line of bearings are available in high-carbon chromium steel, 440C stainless steel, ceramic-hybrid and XD-15 with ceramic or stainless balls. Our bearings are always engineered with deepest groove races possible to accommodate the largest balls possible and feature dual-lip seals that ride in a micro-groove creating a full labyrinth to provide superior protection against the elements.
