Till now i'm very satisfied about this bearing. It's justed in a SlingShot kitesurf bar and makes it posible unspin the frontlines after a kiteloop. I surf at the beach so the bearing wil have a hardtime. There for i choose a sealed rvs bearing with porcelain balls. Time will tell how good the quality really is. Thanx for the fast delevery!!

Nice cermanic Bearings

These bearings will be used for jet engine application for spares due to ABEC-7 rating and ceramic balls instead of steel balls. When both rubber cover are removed from these bearings and proper lubrication and cooling is provided, these bearings can withstand 110 000 RPM. Due to plastic cage, they can be used only to cca 150 deg C temperature range.
