The Black Oxide headset bearings are treated in multiple chemical baths to achieve a 3 micron anti corrosive depth. This process also provides a secondary advantage of heat treatment making them tougher. The BO races then go through a secondary \"super grind” polishing the rolling surface mirror smooth. Both Stainless and BO bearings are engineered with the largest balls possible, feature dual-lip seals riding in a micro-groove (labyrinth) and are filled 90% with extra high pressure Almagard 3752 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, minimizing wear and maximizing life.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eStatic load - 660lbf \/ 2.93kN \u003cbr\u003eWeight - 20.05g\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eid: 36.8 od: 45.8 width: 6.5\u003c\/p\u003e","brand":"Enduro Bearings","offers":[{"title":"Default Title","offer_id":59966001774937,"sku":null,"price":29.61,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0836\/8767\/0105\/files\/Image2_cd7d5fd4-78a8-434b-b21a-b79d2c0ed6e5.jpg?v=1792324353","url":"https:\/\/www.thegrizzlybearingco.co.uk\/en-eu\/products\/enduro-acb-s8551-bo-abec-5-36-8x45-8-x6-5-45-45","provider":"The Grizzly Bearing Co.","version":"1.0","type":"link"}
