(White Ceramic) ☝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 sizes available for Coolpower, Speedway, Inokim quick 2 3, Inokim Light, M board Goliath, Mboard Pro, Shengte Ruima, Dualtron, Passion 10, Patrol/Giant Mountain Bike with Shimano shifter dualtron ultra mx ex ex+ quick 3. Other sizes also available. Please send me the diameters and width when you inquire. Bearings for most motorcycles are available. Silicon nitride bearings are both full ceramic bearings and ceramic hybrid bearings with balls in ceramics and races in steel. Silicon nitride ceramics have good shock resistance compared to other ceramics. Therefore, ball bearings made of silicon nitride ceramic are used in performance bearings. A representative example is use of silicon nitride bearings in the main engines of the NASA's Space Shuttle.[18][19] Since silicon nitride ball bearings are harder than metal, this reduces contact with the bearing track. This results in 80% less friction, 3 to 10 times longer lifetime, 80% higher speed, 60% less weight, the ability to operate with lubrication starvation, higher corrosion resistance and higher operation temperature, as compared to traditional metal bearings.[17] Silicon nitride balls weigh 79% less than tungsten carbide balls. Silicon nitride ball bearings can be found in high end automotive bearings, industrial bearings, wind turbines, motorsports, bicycles, rollerblades and skateboards. Silicon nitride bearings are especially useful in applications where corrosion, electric or magnetic fields prohibit the use of metals. For example, in tidal flow meters, where seawater attack is a problem, or in electric field seekers.[10] Si3N4 was first demonstrated as a superior bearing in 1972 but did not reach production until nearly 1990 because of challenges associated with reducing the cost. Since 1990, the cost has been reduced substantially as production volume has increased. Although Si 3N 4 bearings are still 2–5 times more expensive than the best steel bearings, their superior performance and life are justifying rapid adoption. Around 15–20 million Si 3N 4 bearing balls were produced in the U.S. in 1996 for machine tools and many other applications. Growth is estimated at 40% per year, but could be even higher if ceramic bearings are selected for consumer applications such as in-line skates and computer disk drives.[17]
