Description
The Enduro ACB 3645 3748 BO is a 1-3/8" angular contact headset bearing (37mm x 48mm x 6.5mm: 36/45deg) designed for superior performance and durability. Featuring anti-corrosion Black Oxide/Magnetite coated 52100 High-Carbon Chromium alloy races and grade 10 balls, this bearing offers extended worry-free performance and enhanced corrosion resistance. Engineered with the largest possible balls, dual-lip seals riding in a micro-groove labyrinth, and filled 90% with high-pressure waterproof grease, it provides ultimate protection against sweat and the elements. Its angular contact design ensures even engagement of all balls, spreading force over a larger surface area to decrease friction, minimize wear, and maximize bearing life. This bearing is also known as Ai-70 in the bike industry.
