ACB 3645 CC SXD - 1 1/8" Angular Contact Headset Bearing - 30.2 x 41 x 6.5mm (36 x 45 deg)

This headset bearing promises to be the ultimate and final installation for your bike. These full XD-15 bearings mirror the performance and corrosion resistance of our XD-15 Ceramic-hybrid bearings, typically used for hubs and bottom brackets. However, they feature XD-15 balls specially optimized for the more demanding steering environment. The mechanical properties of XD-15 stainless steel balls surpass ceramic balls, offering superior impact resistance ideal for headset applications. Our extensive testing has proven these bearings with XD-15 balls and races to withstand months in saltwater without any corrosion, setting an unparalleled standard in the market. We're so confident in this material that we offer a lifetime guarantee against corrosion for these full XD-15 headset bearings.

The Enduro range of angular-contact headset bearings begins with Black Oxide treated Chromium steel races, progresses to complete 440C stainless steel, and reaches the pinnacle with XD-15 aerospace-stainless (both races and balls), guaranteed for life. These bearings consistently employ the largest feasible balls, incorporate dual-lip seal maneuvering within micro-grooves (labyrinth), and are 90% filled with high-pressure waterproof grease, ensuring ultimate protection against sweat and environmental factors. Enduro Angular Contact (A/C) bearings are crafted to engage all balls, efficiently distributing force across a larger surface area, thereby reducing friction, minimizing wear, and optimizing longevity.
