It uses a nylon cage, seven high-grade steel balls, ZZ shields, and GCr15 bearing steel for consistent performance.\u003c\/p\u003e\u003ch2\u003eReliable 627 Bearing Construction\u003c\/h2\u003e\u003cp\u003eBoth sides use the same rubber ZZ shield. A thin steel sheet sits inside the rubber shield, and the shields are removable for suitable cleaning and maintenance. The nylon cage keeps the seven balls evenly spaced as the bearing rotates.\u003c\/p\u003e\u003ch3\u003eCorrect Fit and Setup\u003c\/h3\u003e\u003cp\u003eThe 627 bearing measures 7 x 22 x 7 mm. The 7 mm bore is for compatible 7 mm axles and will not fit an 8 mm axle. Each pack contains 16 bearings, enough for a standard eight-wheel roller skate setup. Spacers are not included.\u003c\/p\u003e\u003ch3\u003eRunning Surfaces and Lubrication\u003c\/h3\u003e\u003cp\u003eThe outer ring normally goes through rough grinding, fine grinding, and honing. These are mechanical operations that remove material by grinding, without additives. There is no separate polishing process. The manufacturer states that light oil is used.\u003c\/p\u003e\u003cp\u003eAfter cleaning, allow the bearings to dry fully before applying suitable lubricant and refitting the shields. Seat the bearings squarely and check that every wheel rolls freely.\u003c\/p\u003e\u003ch2\u003eTechnical Specifications\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBearing type:\u003c\/strong\u003e 627\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDimensions:\u003c\/strong\u003e 7 x 22 x 7 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShields:\u003c\/strong\u003e ZZ, rubber on both sides, with a thin internal steel sheet; removable\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCage:\u003c\/strong\u003e Nylon\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBearing steel:\u003c\/strong\u003e GCr15\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBall complement:\u003c\/strong\u003e 7 high-grade steel balls\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLubrication:\u003c\/strong\u003e Light oil\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003e\u003cstrong\u003ePack of 16 pieces.\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eSpacers are not included.\u003c\/strong\u003e\u003c\/p\u003e","brand":"Bont","offers":[{"title":"1 Set (16 bearings)","offer_id":47930603864312,"sku":"627-PRO-PACK16","price":39.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0048\/6242\/files\/bont-pro-627-roller-skate-bearings-1-set-16-bearings-1259975513.png?v=1790339653","url":"https:\/\/bont.com\/en\/products\/bont-627-pro-roller-bearings","provider":"Bont Skates Online Shop","version":"1.0","type":"link"}
