Silicon nitride ceramic balls run against hardened steel raceways, delivering a surface hardness and smoothness that steel-on-steel simply can't match. A reinforced polymer cage holds the assembly together, while CeramicSpeed's own grease and precision seals keep contaminants out and performance consistent over time.\u003c\/p\u003e\n\n\u003cp\u003eCeramicSpeed rates these bearings at three to five times the service life of standard bearings — a claim rooted in the inherent hardness and corrosion resistance of silicon nitride. The sealing design is worth noting too: keeping dirt and moisture out from the start means the bearing maintains its low-friction character across thousands of kilometres, not just the first few rides.\u003c\/p\u003e\n\n\u003ch3\u003eCeramicSpeed Ceramic Bearing - 6803 Specs at a Glance\u003c\/h3\u003e\n\u003cul class=\"specs_at_a_glance\"\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBall material:\u003c\/strong\u003e Silicon nitride ceramic\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRaceway material:\u003c\/strong\u003e Hardened steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCage material:\u003c\/strong\u003e Reinforced polymer\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLubrication:\u003c\/strong\u003e CeramicSpeed ceramic-optimised grease\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBearing designation:\u003c\/strong\u003e 6803\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e","brand":"CeramicSpeed","offers":[{"title":"Default Title","offer_id":43705502236716,"sku":"101230","price":116.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0608\/7684\/9196\/files\/ceramicspeed-ceramic-bearing-6803-1615916.jpg?v=1771301647","url":"https:\/\/ricycles.com\/products\/ceramicspeed-ceramic-bearing-6803","provider":"RA Cycles","version":"1.0","type":"link"}
