ENDURO BEARINGS Acb 4545 1125t ss - 440c stainless (angular contact) - 30,15x41x7 (45x45°)

Upgrade your bike with the ACB 4545 1125T SS angular contact headset bearing, designed for superior durability and corrosion resistance. Crafted from high-grade 440C stainless steel balls and races, this bearing offers exceptional strength, hardness, and wear resistance, making it ideal for demanding riding conditions. Measuring 30.15mm x 41mm x 7mm with a 45°x45° contact angle, it is also known in the cycling industry by the part number MH-P03H7.

Enduro only uses 440C stainless steel for its high-performance bearings, ensuring long-lasting operation even in less-than-ideal environments. Although stainless steel has approximately 20% less load capacity and is slightly softer than standard chromium steel (52100), it excels in wet conditions, frequent washing, or environments where sweat is prevalent. These bearings feature LLB-type seals and CRC Marine grease for enhanced waterproofing and protection against the elements.

All Enduro stainless headset bearings come with a limited lifetime warranty, including those used in many top headset brands with a 110-year warranty. Designed with larger balls and dual-lip labyrinth seals, they provide maximum protection against dirt, water, and wear, ensuring smooth performance over time. The Angular Contact (A/C) design distributes load evenly across all balls, reducing premature wear and significantly extending bearing lifespan.
