Engineered with precision and featuring 440C stainless steel balls and races, this angular contact headset bearing is designed to provide riders with exceptional durability, corrosion resistance, and reliable performance in various conditions. Explore the key features that make the Enduro Headset Bearing a top choice for cyclists seeking an upgrade in their headset components.

Superior Corrosion Protection with 440C Stainless Steel:

Not all stainless steel is created equal, and Enduro understands the importance of using the highest-quality materials for superior performance. The ACB 4545 150 SS headset bearing is crafted with 440C stainless steel balls and races. This specific alloy offers the highest strength, hardness, and wear resistance within the 440-series stainless alloys with high carbon content. The result is a headset bearing that excels in corrosion protection, ensuring long life and reliable performance even in less-than-ideal conditions.

Engineered for Durability and Longevity:

Enduro's commitment to engineering excellence is evident in the design of this angular-contact headset bearing. The Black Oxide treated chromium steel races serve as a robust foundation, ensuring durability and longevity. The use of 440C stainless steel takes the durability factor up a notch, making this bearing an excellent choice for riders who demand the highest standards from their components.

Optimized for Wet Conditions and Sweat Resistance:

Whether you frequently ride in wet conditions or face the challenge of sweat exposure, the ACB 4545 150 SS headset bearing is well-suited for the task. Enduro bearings use LLB type seals and CRC Marine Grease in these bearings to enhance water resistance. The dual-lip seals ride in a micro-groove (labyrinth), providing an additional layer of defense against the elements. With 90% high-pressure waterproof grease fill, this bearing excels in protecting against sweat and environmental factors.

Enduro's Angular Contact Design for Reduced Friction:

The angular contact design of Enduro's A/C bearings is a key feature contributing to reduced friction, minimized wear, and maximized bearing life. The evenly engaged balls spread force over a larger surface area, enhancing the bearing's performance and efficiency. This design choice aligns with Enduro's commitment to providing cyclists with components that deliver an exceptional riding experience.

Versatile Application and Compatibility:

The ACB 4545 150 SS headset bearing is engineered for versatility, making it suitable for various headset applications. Its compatibility extends to popular headset brands, reflecting its widespread use in the cycling community. Whether you ride in challenging conditions or seek top-tier performance, this headset bearing is designed to meet the demands of discerning cyclists.
