ACB 68025C - 1-1/8 Angular Contact Black Oxide treated Headset bearing (33.15mm x 46.9mm x 6.5mm: 36 x 45deg)

Angular-contact headset bearing featuring anti-corrosion Black Oxide/Magnetite treated 52100 High-Carbon Chromium alloy races paired with grade 10 Balls.lack Oxide treatment provides an extra level of corrosion resistance and extended worry-free performance

This size bearing is also known in the bike Industry by part number HD408K

The Enduro line of angular-contact headset bearings start with Black Oxide treated Chromium Steel races, steps up to full 440C stainless steel, and the top of the line is, lifetime-guaranteed, XD15 aerospace-stainless (races and balls). They are always engineered with the largest balls possible, feature dual-lip seals riding in a micro-groove (labyrinth) and are filled 90% with high pressure water proof grease for the ultimate protection against sweat and the elements. Enduro Angular Contact (A/C) bearings are designed so all balls are evenly engaged to spread the force over a larger surface area, minimizing wear and maximizing life.
