6808 LLB BO 45 1-1/2 Black Oxide Headset Bearing

6808 LLB BO 45 - 1-1/2 Black Oxide Coated Headset Bearing This 1 1/2 headset bearing features anti-corrosion Black Oxide/Magnetite coated 52100 High-Carbon Chromium alloy races paired with grade 10 Balls. Black Oxide coating provides an extra level of corrosion resistance and extended worry-free performance. The Enduro line of headset bearings begin with chromium steel, Black Oxide finish A/C type and then offer full 440C stainless steel at the top. They are always engineered with the largest balls possible and dual lip seals riding in a micro-groove for ultimate protection against sweat and the elements. They are filled 90% with high pressure water proof grease, so you never have to guess if there is grease inside. Enduro Angular Contact (A/C) bearings are designed so all balls are evenly engaged to spread the force over a larger surface area, pressure water and minimizing wear.
