Stainless steel headset angular contact ball bearing with 33mm inner diameter, 44mm outer diameter, 6mm thickness and double-lip type sealing.
Enduro Bearings don't mess around with inexpensive headset bearings, it's simply not worth it. While many headset makers will offer you Cr-Mo or standard steel headsets for your carbon road bike, steel cross bike, or full suspension mountain bike, they feel that's like putting bias ply tires on a rally car. Enduro Bearings don't offer the entry level for headset bearings. Instead they begin with chromium steel, Black Oxide finish A/C type and then offer full 440C stainless steel at the top. They are always engineered with the largest balls possible and dual lip seals riding in a micro groove for ultimate protection against sweat and the elements. They are filled 90% with high pressure water proof grease, so you don't have to ever guess if there is grease inside.
Stainless steel provides maximum corrosion resistance in applications and environments where critical. It has 20% less load capacity than the 52100 chromium steel, used in most of Enduro Bearings, but with far superior corrosion resistance.
In standard radial bearings, only 3 or 4 balls make contact during the load, at any given time. In Angular Contact (A/C) bearings, ALL balls are engaged and spread the force over a larger surface area, to decrease friction and minimize wear.
