It is made for quad speed skating and quad long distance racing, where every watt saved matters.\u003c\/p\u003e\n\u003ch2\u003eWhy skaters choose Swiss Ceramic 627\u003c\/h2\u003e\n\u003cp\u003eIt uses a high grade Si3N4 hybrid ceramic. According to the manufacturer it is around 50% lighter than steel yet 40% more robust, runs up to 100,000 rpm under load, and saves 0.8 to 1.0 watts per bearing against typical precision steel, which adds up across a full set over a long race. A nylon thermo molded cage positions each ball accurately, and double lumen seals on polished rims give an almost frictionless shield against dust and water. The Si3N4 is cryogenically treated at minus 300 degrees Fahrenheit to refine the structure for efficiency and durability.\u003c\/p\u003e\n\u003ch2\u003eSpecification\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBalls:\u003c\/strong\u003e Si3N4 hybrid ceramic, cryogenically treated\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCage:\u003c\/strong\u003e nylon thermo molded\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeals:\u003c\/strong\u003e double lumen seals on polished rims\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSize:\u003c\/strong\u003e 627, 7mm bore by 22mm outer by 7mm wide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBest for:\u003c\/strong\u003e quad speed skating and quad long distance racing on 627 axles\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eCheck your axle size first\u003c\/h2\u003e\n\u003cp\u003eThis is a 627 bearing, with a 7mm bore.
