Ceramic-Steel Hybrid Bearing for Escooters/ Mountain Bikes/Skateboards/Motorcycles. Balls: Silicon Nitride Ceramic Rings: Bearing Steel For mechanics/performance enthusiasts ONLY! Made of Silicon Nitride. (Black ceramic) If you want the smoothest sensation and the highest speed, you can choose full ceramic bearings. ☝Q: How do I know it is real ceramic? 🔧A: Feel free to rub the ceramic ball against the floor made of concrete and see what happens to the surface when you view it :) -High strength over a wide temperature range -High fracture toughness -High hardness -Outstanding wear resistance -Good thermal resistance -Good chemical resistance Bearings of different dimensions available for Coolpower, Speedway 3, Inokim quick 2, Inokim Light, M board Goliath, Mboard Pro, dualtron, jack hot, zero, zoom air 2, Shengte Ruima, Dualtron, Passion 10, Patrol/Giant Mountain Bike with Shimano shifter. Other sizes also available. Please send me the diameters and width when you inquire. Bearings for most motorcycles are available. A ceramic is an inorganic, nonmetallic[a] solid material comprising metal, nonmetal or metalloid atoms primarily held in ionic and covalent bonds. The crystallinity of ceramic materials ranges from highly oriented to semi-crystalline, and often completely amorphous (e.g., glasses). Varying crystallinity and electron consumption in the ionic and covalent bonds cause most ceramic materials to be good thermal and electrical insulators (extensively researched in ceramic engineering). With such a large range of possible options for the composition/structure of a ceramic (e.g. nearly all of the elements, nearly all types of bonding, and all levels of crystallinity), the breadth of the subject is vast, and identifiable attributes (e.g. hardness, toughness, electrical conductivity, etc.) are hard to specify for the group as a whole. General properties such as high melting temperature, high hardness, poor conductivity, high moduli of elasticity, chemical resistance and low ductility are the norm,[1] with known exceptions to each of these rules (e.g. piezoelectric ceramics, glass transition temperature, superconductive ceramics, etc.). Many composites, such as fiberglass and carbon fiber, while containing ceramic materials, are not considered to be part of the ceramic family.[2] The word "ceramic comes from the Greek word κεραμικός (keramikos), "of pottery" or "for pottery",[3] from κέραμος (keramos), "potter's clay, tile, pottery".[4] The earliest known mention of the root "ceram-" is the Mycenaean Greek ke-ra-me-we, "workers of ceramics", written in Linear B syllabic script.[5] The word "ceramic" may be used as an adjective to describe a material, product or process, or it may be used as a noun, either singular, or, more commonly, as the plural noun "ceramics".[6] The earliest ceramics made by humans were pottery objects, including 27,000-year-old figurines, made from clay, either by itself or mixed with other materials like silica, hardened, sintered, in fire. Later ceramics were glazed and fired to create smooth, colored surfaces, decreasing porosity through the use of glassy, amorphous ceramic coatings on top of the crystalline ceramic substrates.[7] Ceramics now include domestic, industrial and building products, as well as a wide range of ceramic art. In the 20th century, new ceramic materials were developed for use in advanced ceramic engineering, such as in semiconductors.
