A multi-stage chemical treatment creates a 3-micron anti-corrosive layer while simultaneously enhancing hardness through heat treatment. The races undergo precision super-grind polishing to achieve a mirror-smooth rolling surface. Oversized grade 10 balls distribute loads evenly across a larger contact area, reducing wear and extending bearing life. Dual-lip seals with micro-groove labyrinth design and 90% fill of high-pressure Almagard 3752 grease provide comprehensive protection against moisture and environmental degradation—essential for reliable headset performance in demanding conditions.\u003c\/span\u003e\u003c\/p\u003e\n\u003ch5\u003e\u003cspan\u003eSPECIFICATIONS \u003c\/span\u003e\u003c\/h5\u003e\n\u003cul\u003e\n\u003cli\u003eStatic load - 935lbf \/ 4.15kN\u003c\/li\u003e\n\u003cli\u003eWeight - 19g\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Enduro Bearings","offers":[{"title":"Default Title","offer_id":44649033498694,"sku":"EBHSACB36451125BO","price":29.95,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/3081\/4790\/files\/EBHSACB36451125BO.jpg?v=1771297430","url":"https:\/\/crooze.com.au\/products\/enduro-acb-3645-1125-bo-1-1-8-angular-headset-bearing-30-5x41-8x6-3mm-36x45","provider":"Crooze","version":"1.0","type":"link"}
