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.\u003c\/span\u003e\u003cbr\u003e\u003cbr\u003e\u003cspan\u003eStainless 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.\u003c\/span\u003e\u003cbr\u003e\u003cbr\u003e\u003cspan\u003eIn 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.\u003c\/span\u003e\u003cbr\u003e\u003cbr\u003e\u003cspan\u003eABEC 3 bearings use grade 10 Chromium Steel Balls and 52100 High Carbon Chromium Alloy Races.\u003c\/span\u003e\u003cbr\u003e\u003cspan\u003eThe high precision balls are within 10\/1.000.000″ round, twice as round as the industry standard, at it's highest level.\u003c\/span\u003e\u003cbr\u003e\u003cspan\u003eThe alloy races are made from a vacuum de-gassed process for the purest chromium alloy steel, hardened to R-62, extremely tough and very durable. Polished to a mirror finish for ABEC-3 precision and noiseless movement. The riveted Steel Retainer stands for toughness, ABEC-3 tolerances and noise tested.\u003c\/span\u003e\u003c\/p\u003e","brand":"Enduro","offers":[{"title":"32.75 x 41.75 x 6 mm","offer_id":42380946112560,"sku":"ENDURO-ACB4545136SS","price":33.0,"currency_code":"USD","in_stock":true},{"title":"37 x 46.85 x 7 mm","offer_id":42380946145328,"sku":"ENDURO-ACB4545137SS","price":39.75,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0272\/9394\/1808\/files\/2566572.jpg?v=1756911399","url":"https:\/\/movatik.com\/products\/enduro-headset-bearing-acb-4545-precision-stainless-steel-headset-bearing-set","provider":"Movatik","version":"1.0","type":"link"}
