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

The angular-contact headset bearing boasts anti-corrosion due to its Black Oxide/Magnetite coating on 52100 High-Carbon Chromium alloy races, partnered with grade 10 Balls. This Black Oxide layer enhances corrosion resistance, ensuring prolonged, worry-free performance.

Within the Enduro series, angular-contact headset bearings initiate with Black Oxide treated Chromium steel races, advance to complete 440C stainless steel, and reach the epitome with the XD-15 aerospace-stainless variant (featuring both races and balls), offering a lifetime guarantee. These bearings consistently prioritize the use of the largest feasible balls, integrate dual-lip seals gliding within micro-grooves (labyrinth), and are filled up to 90% capacity with high-pressure waterproof grease, offering the ultimate protection against sweat and environmental elements. The Enduro Angular Contact (A/C) bearings are meticulously engineered to uniformly engage all balls, effectively distributing force across a broader surface area, thereby reducing friction, minimizing wear, and maximizing the bearings' longevity.
