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 - 935lbf \/ 4.15kN \u003c\/strong\u003e\u003cbr\u003e\u003cstrong\u003eWeight - 25.25g\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cp\u003eid: 37 od: 48 width: 6.5 width\u003c\/p\u003e","brand":"Enduro Bearings","offers":[{"title":"Default Title","offer_id":56707900146009,"sku":null,"price":23.0,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0836\/8767\/0105\/files\/Image3_2368eb21-5281-49ed-9c24-cecf3379664b.jpg?v=1763896557"},{"product_id":"enduro-hdk-0010-maxhit-zero-stack-headset-kit-zs44-zs56","title":"Enduro HDK-0010 Maxhit Zero Stack Headset Kit (ZS44\/ZS56)","description":"\u003cp\u003e\u003cstrong\u003eNOTE: THIS IS, CURRENTLY, IN STOCK WITH OUR SUPPLIER; HOWEVER, DUE TO POPULARITY WE CANNOT GUARANTEE THAT THEY WILL STILL BE IN STOCK WHEN ORDERED.
