1pcs 2RS Double Sealed Bearing Steel Hybrid Ceramic Ball Bearing,Silicon Nitride Balls,Low Friction,6807 35 * 47 * 7

Composition:Bearing steel+Silicon nitride ceramic balls+Nylon retainer+Rubber seal cover.Hybrid bearings with ceramic balls as rolling elements offer enhanced wear resistance,non- properties,and lower specific gravity.The use of ceramic materials enables bearings to operate normally under higher speeds and more demanding conditions,reducing wear,noise,vibration,and maintenance requirements,thereby achieving a longer service life.Thanks to their durability and low-wear characteristics,hybrid ceramic bearings have relatively lower maintenance costs

• The lightweight characteristics of silicon nitride balls reduce the centrifugal force during high-speed operation,reducing friction and wear.
• The smooth surface of silicon nitride ceramic balls results in low friction coefficients and low noise during operation.
