ACB 3645 CC SXD - XD-15 Ceramic (Angular Contact) - 30,2x41x6,5 (36x45°)

ACB 3645 CC SXD - 1-1/8 Angular Contact Headset Bearing - (30.2mm x 41mm 6.5mm: 36x45 deg) Internal headset bearing featuring XD-15 races and balls to provide a lifetime corrosion resistance This is the last headset bearing you will ever install into your bike. -
A recent Enduro development, these full XD-15 bearings are virtually identical in performance and corrosion resistance to our XD-15 Ceramic-hybrid bearings used for hubs and bottom brackets, but lend themselves better to the more abusive application of the headset. The mechanical properties of stainless steel balls provide a level of impact resistance superior to ceramic balls for headset application. Enduro testing of bearings withXD15 races have been run in salt water for months without any corrosion, there is simply nothing on the market that compares. We are so confident in this material that we guarantee these full XD-15 headset bearings for life, against corrosion. This size bearing is also known in the bike Industry by these part numbers: 27287-1046-004 HSS0130K TH-873E MR-122 The Enduro line of headset bearings consists of two basic performance levels that are a substantial step up from standard bike industry specifications. Enduro "entry-level" headset bearings feature premium materials like Black-Oxide treated races and carry a two year warranty, while our premium 440C stainless headset bearings carry a full lifetime warranty. All Enduro bearings are always engineered with the largest balls possible and feature dual lip labyrinth seals for maximum protection against sweat and the elements and to contain the 90% high pressure water proof grease, keeping everything running smoothly for the duration. The Angular Contact (A/C) design of Enduro headset bearings allow all balls in the bearing to engage the load, spreading the force over a larger surface area minimizing any possibility of premature wear and greatly extending bearing life. Static load - 935lbf / 4.15kN - Weight - 19.2g -
