Enduro Bearings 15307 CXD MR LLB XD-15 Ceramic bearing, 15x30x7

CXD MR 15307 LLB - XD15 Ceramic - Hybrid, ABEC-5, Radial Bearing (C3 Clearance) - 15mm x 30mm x 7mm

The ultimate upgrade. An Enduro Bearings exclusive, our XD15 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 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 XD15 ceramic-hybrid bearings is that, unlike other bearings, they only get better with time and use. As the bearings wear in, the super-hard ceramic balls actually make the XD15 races even smoother. Compared to other ceramic-hybrid bearings on the market that claim speed and power advantages on day one, Enduro XD15 bearings not only provide the same initial advantages but will become faster and smoother with time and use, while other ceramic-hybrid options will only get slower.

We are so confident in the performance of XD15 Ceramic - Hybrid bearings that we offer an unlimited lifetime bearing and race warranty. This size bearing is used primarily in hubs. The Enduro line of bearings is available in high-carbon chromium steel, 440C stainless steel, ceramic-hybrid, and XD15 with ceramic or stainless balls. Our bearings are always engineered with the deepest groove races possible to accommodate the largest balls and feature dual-lip seals that ride in a micro-groove, creating a full labyrinth to provide superior protection against the elements.
