Silicon nitride ceramic balls run against hardened steel raceways, and the coated version adds an additional layer to the raceway surface — further reducing friction and extending service life well beyond what a standard steel bearing delivers. CeramicSpeed rates these bearings at three to five times the longevity of industry-standard alternatives.\u003c\/p\u003e\n\n\u003cp\u003eA reinforced polymer cage keeps the balls aligned and spaced consistently, while \u003cstrong\u003especialized seals\u003c\/strong\u003e are designed to keep dirt and moisture out without adding meaningful drag. The bearings are packed with CeramicSpeed's own grease formulation, matched to the materials and tolerances of the ceramic ball set. The result is a bearing that maintains its performance characteristics over a significantly longer service interval than conventional options.\u003c\/p\u003e\n\n\u003ch3\u003eCeramicSpeed Ceramic Coated Bearing - 6903 Specs at a Glance\u003c\/h3\u003e\n\u003cul class=\"specs_at_a_glance\"\u003e\n  \u003cli\u003eBearing type: Ceramic coated — silicon nitride balls with coated hardened steel raceways\u003c\/li\u003e\n  \u003cli\u003eCage material: Reinforced polymer\u003c\/li\u003e\n  \u003cli\u003eLubrication: CeramicSpeed proprietary grease\u003c\/li\u003e\n  \u003cli\u003eSealing: Sealed against dirt and moisture ingress\u003c\/li\u003e\n  \u003cli\u003eRated service life: 3–5x longer than standard steel bearings (manufacturer claim)\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e","brand":"CeramicSpeed","offers":[{"title":"Default Title","offer_id":43705512591404,"sku":"101275","price":177.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0608\/7684\/9196\/files\/ceramicspeed-ceramic-coated-bearing-6903-8196862.jpg?v=1771301647","url":"https:\/\/ricycles.com\/products\/ceramicspeed-ceramic-coated-bearing-6903","provider":"RA Cycles","version":"1.0","type":"link"}
