Upgrade your bike with the high-performance ACB 4545 125L SS angular contact headset bearing, designed for durability and corrosion resistance. Crafted from premium 440C stainless steel balls and races, this bearing offers superior strength, hardness, and wear resistance, making it ideal for challenging environments. Known in the cycling industry by part numbers such as MR168, 970S, IS46, and TH MR082, it ensures long-lasting performance. Unlike standard stainless steel, 440C provides enhanced corrosion protection and mechanical properties, requiring advanced heat and cryogenic treatments. Perfect for wet conditions or frequent bike washes, this bearing is also equipped with LLB seals and CRC Marine grease for added waterproofing against the elements. Enduro's stainless headset bearings are compatible with many top brands, backed by a limited lifetime warranty. Featuring dual lip labyrinth seals and large balls, the Angular Contact (A/C) design distributes load evenly, reducing wear and extending bearing life. Weighing only 25.5g with a static load capacity of 980lbf (4.35kN), this bearing is a reliable choice for demanding cycling applications.
