The 6808 is a single-row, thin-section miniature deep groove ball bearing from the 6800 series, manufactured in an open configuration without shields or seals. Featuring a 40 mm bore and a highly compact 52 mm outer diameter, it delivers an extremely slim 7 mm cross-section. This open-type design is specifically engineered for internal machinery applications where the bearing operates within an already sealed housing, such as an oil bath or centralized lubrication system. By omitting the sealing components, the 6808 Open achieves the lowest possible starting and running torque, making it the premier choice for ultra-high-speed, space-constrained assemblies where frictional losses must be completely minimized.
