Enduro 6808 LLB BO 45 - 1-1/2 Black Oxide treated Headset Bearing (40mm x 52mm x 7mm: 45deg ID only)

6808 LLB BO 45 - 1-1/2 Black Oxide treated Headset Bearing (40mm x 12mm x 7mm: 45deg ID only)

Radial design headset bearing featuring anti-corrosion Black Oxide/Magnetite treated 52100 High-Carbon Chromium alloy races paired with grade 10 Balls. Black 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:
HSS 6011

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, decreasing friction, minimizing wear and maximizing life.
