Enduro ACB 3645 3344 SS delivers premium 440C stainless steel angular contact performance built to laugh off mud, rain, sweat, and everything the trail throws at your headset.

Not all stainless steel is created equal, and Enduro Bearings built the ACB 3645 3344 SS to prove it. This 1-1/8 angular contact headset bearing uses 440C stainless steel balls and races throughout, which sits at the top of the 440-series lineup with the highest strength, hardness, and wear resistance of the bunch. It takes special heat treatment and cryogenic treatment to get there, but the result is a bearing that shrugs off corrosion in the kind of conditions that chew through lesser hardware.

The angular contact design means all the balls stay engaged under load, spreading force evenly across the bearing instead of piling it onto just a few contact points. Enduro pairs that with the largest balls possible, dual-lip LLB-type seals running in a micro-groove labyrinth, and Almagard 3752 grease packed in at 90% fill. That combination keeps water, mud, and sports drink out and keeps you rolling smooth for the long haul. At just 20g and a static load rating of 935lbf / 4.15kN, this bearing punches well above its weight.

This size bearing is also known in the bike industry by these part numbers: ACB3344H6 and AC3344. If your headset has been eating bearings every season, this is the upgrade that stops that conversation for good.

Why You'll Like It

Wet-weather riders and enduro regulars get a headset bearing that is genuinely built for the worst your local trail can dish out. Your headset stays smooth and precise even after deep mud sections, creek crossings, and post-ride hose-downs that would corrode a standard bearing in a few seasons. The 440C stainless construction, Almagard 3752 grease, and labyrinth seals mean you spend more time riding and less time wrenching.

Key Features

  • 440C stainless steel balls and races for superior corrosion resistance, the toughest and most wear-resistant of all standard 440-series stainless alloys
  • Angular contact design keeps all balls evenly engaged under load, spreading force over a larger surface area to minimize wear and maximize bearing life
  • LLB-type dual-lip seals in a micro-groove labyrinth and Almagard 3752 waterproof grease packed at 90% fill for serious weather protection
  • 1-1/8 sizing (33mm x 44mm x 6mm, 36 x 45 deg), 20g weight, and a 935lbf / 4.15kN static load rating
  • Also known in the bike industry as ACB3344H6 and AC3344, and found as OEM spec inside many popular headset brands
