ACB 6806 CC SS- 1-3/8"" 440C stainless steel Angular Contact Headset bearing (37mm x 49mm x 6.5mm; 36 x 45deg)
Angular-contact headset bearing featuring 440C stainless steel balls and races for superior corrosion protection.
This size bearing is also known in the bike Industry by part number HD446K.
Not all stainless steel is created equal.
Enduro only uses 440C stainless steel balls and races to provide long life and superior corrosion resistance in applications and environments that may be less than ideal. 440C has the highest strength, hardness, and wear resistance of all the standard 440-series stainless alloys with high carbon content. As expected, it is also the most expensive of the 440 series alloys and requires multiple rounds of heat treatment and cryogenic treatments to achieve its superior mechanical properties. Though stainless steel has 20% less load capacity and is slightly softer than our standard 52100 chromium steel used in most of our bearings, stainless steel is an excellent alternative for use in wet conditions, if you wash your bike often, or where sweat can be a problem. Enduro Bearings also uses LLB type seals and CRC Marine Grease in these bearings to additionally water proof against the elements. Enduro 440C stainless headset bearings are the same bearings found in many popular headset brands, including those that carry a 110 year warranty.
The Enduro line of angular-contact headset bearings start with Black Oxide treated Chromium Steel races, steps up to full 440C stainless steel, and the top of the line is, lifetime-guaranteed, XD15 aerospace-stainless (races and balls). They are always engineered with the largest balls possible, feature dual-lip seals riding in a micro-groove (labyrinth) and are filled 90% with high pressure water proof grease for the ultimate protection against sweat and the elements. Enduro Angular Contact (A/C) bearings are designed so all balls are evenly engaged to spread the force over a larger surface area, decreasing friction, minimizing wear and maximizing life.

I recently took my dated and tired old racing bike along to Leeli Cycles for some much needed work. I was cheerfully greeted by Ben the very friendly owner and number one mechanic. He suggested a full service and looked over the bike to access the condition of the other cycle components. A very comprehensive quote was later emailed to me listing all the parts that Ben would require to complete the job. He phoned me as soon as my bike was ready and I hurried along to pick it up. My first reaction was, wow! It looked as good as new and fully roadworthy again. Ben had done an incredible job in transforming my old racer back to its former glory! I'm very pleased to have used Leeli Cycles along with Ben's wealth of mechanical knowledge, sound advice and attention to detail. Even happier still to support this amazing small local business offering great value and excellent customer service. An outstanding shop in every way for all your cycling needs with the personal touch. Pop in and see for yourself. I guarantee you won't be dissapointed.
