6800 Series ball bearing


Deep groove ball bearings
are versatile, self-retaining bearings with solid outer rings, inner rings and ball and cage assemblies.


The 6800 has a lower coefficient of friction and higher speed rating compared to other ball bearing types of the same size. When the use of a thrust type ball bearing is not suitable due to high speeds the 6800 series can be used to bear pure axial loads. The 6800 series is available in open, sealed or shielded configurations.


With single ring groove Single shielded single sealed
With locatining snap ring Double Shielded double sealed
