ZrO2 Zirconia Full Ceramic Ball Bearing Double Sealed Resistant Corrosion
Material: ZrO2 Zirconia，The ferrule and rolling ball are made of zirconia (zRO2) ceramic material, Sealing cover and the retainer is made of polytetrafluoroethylene (PTFE) 。. -On the basis of ordinary bearings, sealing covers are installed on both sides, which can effectively prevent dust and impurities from entering, avoid bearing jamming, and prolong bearing life.
Si3N4 Silicon Nitride Ceramic Ball Bearing Resistant Corrosion/high Temperature
Material: Silicon Nitride. -Self-lubricating: ceramic bearings have good self-lubricating properties due to their small friction coefficient and good surface smoothness, especially silicon nitride materials have better lubricating properties!
420 Stainless Steel + Si3N4 Ceramic Ball Bearing For Toy Cars、Fishing Wheel
High rotational speed, ceramic balls have oil-free self-lubricating properties, and ceramic ball friction coefficient is small. Therefore, ceramic ball bearings have high rotational speed and do not lag, and can idle for more than 20-30 seconds。.
