Enduro Sealed Angular Contact Headset Bearing 4545 1125 BO - 1 1/8" - 30.5 x 41.8 x 6.5mm (45 x 45 deg)

ACB 4545 1125 BO - 1 1/8" Black-Oxide Angular Contact Headset Bearing - 30.5 41.8 x 6.5mm (45 x 45 deg)

The angular-contact headset bearing showcases Black Oxide/Magnetite-coated 52100 High-Carbon Chromium alloy races matched with grade 10 balls. This Black Oxide coating augments the corrosion resistance, ensuring prolonged and worry-free performance.

Beginning with Black Oxide treated Chromium Steel races, the Enduro series of angular-contact headset bearings progresses to complete 440C stainless steel. At the pinnacle stands the XD-15 aerospace-stainless series, guaranteed for a lifetime and inclusive of races and balls. These bearings are consistently engineered to accommodate the largest feasible balls, incorporating dual-lip seals that ride within a micro-groove (labyrinth). Filled to 90% capacity with high-pressure waterproof grease, they provide ultimate protection against sweat and environmental elements. The Enduro Angular Contact (A/C) bearings are meticulously designed to uniformly engage all balls, effectively distributing force across a larger surface area, thereby minimizing wear and extending the bearing's lifespan.
