A thin layer of suitable grease should be applied to the outer surface and contact surfaces of the new bearing to prevent moisture and creaking.\u003c\/p\u003e\n\u003chr\u003e\n\u003ch2\u003eTechnical specifications and features\u003c\/h2\u003e\n\u003ch3\u003eKey features\u003c\/h3\u003e\n\u003cul\u003e\n\n\t\u003cli\u003eCema headset bearing for a bicycle headset\u003c\/li\u003e\n\n\t\u003cli\u003eACB \/ angular contact bearing design\u003c\/li\u003e\n\n\t\u003cli\u003eDimensions 41.8 x 30.1 x 6.5 mm\u003c\/li\u003e\n\n\t\u003cli\u003eContact angle 45°\/45°\u003c\/li\u003e\n\n\t\u003cli\u003eChrome steel construction\u003c\/li\u003e\n\n\t\u003cli\u003eReplacement bearing for a worn or pitted headset bearing\u003c\/li\u003e\n\n\t\u003cli\u003eSuitable for compatible frames and headset systems\u003c\/li\u003e\n\n\t\u003cli\u003eAlways select based on the dimensions and angles of the old bearing\u003c\/li\u003e\n\n\t\u003cli\u003eSold as a single bearing\u003c\/li\u003e\n\n\n\u003c\/ul\u003e\n\u003ch3\u003eTechnical specifications\u003c\/h3\u003e\n\u003cul\u003e\n\n\t\u003cli\u003e\n\n\u003cstrong\u003eProduct:\u003c\/strong\u003e Cema Headset Bearing 41.8 x 30.1 x 6.5\u003c\/li\u003e\n\n\t\u003cli\u003e\n\n\u003cstrong\u003eProduct type:\u003c\/strong\u003e Headset bearing\u003c\/li\u003e\n\n\t\u003cli\u003e\n\n\u003cstrong\u003eBearing type:\u003c\/strong\u003e ACB \/ angular contact bearing\u003c\/li\u003e\n\n\t\u003cli\u003e\n\n\u003cstrong\u003eMaterial:\u003c\/strong\u003e Chrome steel\u003c\/li\u003e\n\n\t\u003cli\u003e\n\n\u003cstrong\u003eOuter diameter:\u003c\/strong\u003e 41.8 mm\u003c\/li\u003e\n\n\t\u003cli\u003e\n\n\u003cstrong\u003eInner diameter:\u003c\/strong\u003e 30.1 mm\u003c\/li\u003e\n\n\t\u003cli\u003e\n\n\u003cstrong\u003eHeight \/ width:\u003c\/strong\u003e 6.5 mm\u003c\/li\u003e\n\n\t\u003cli\u003e\n\n\u003cstrong\u003eContact angle:\u003c\/strong\u003e 45°\/45°\u003c\/li\u003e\n\n\t\u003cli\u003e\n\n\u003cstrong\u003eColor:\u003c\/strong\u003e Silver \/ Black\u003c\/li\u003e\n\n\t\u003cli\u003e\n\n\u003cstrong\u003eManufacturer product ID:\u003c\/strong\u003e SRC-HS-JS09\u003c\/li\u003e\n\n\t\u003cli\u003e\n\n\u003cstrong\u003eEAN \/ GTIN:\u003c\/strong\u003e 4712910900641\u003c\/li\u003e\n\n\t\u003cli\u003e\n\n\u003cstrong\u003eSales unit:\u003c\/strong\u003e 1 bearing\u003c\/li\u003e\n\n\n\u003c\/ul\u003e","brand":"CEMA","offers":[{"title":"Default Title","offer_id":57434968326468,"sku":"SRC-HS-JS09","price":18.5,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0987\/6068\/7940\/files\/cema-ohjainlaakeri-41-8x30-1x6-5_orig.jpg?v=1791571818","url":"https:\/\/www.ridemore.fi\/en\/products\/cema-headset-bearing-418-x-301-x-65","provider":"Ride More","version":"1.0","type":"link"}
