The F69 series is positioned at the intersection of a narrow-profile design and medium-load capacity. With an outside diameter falling between that of the 68 and 60 series, it offers greater rigidity than ultra-thin series bearings while retaining the advantage of a narrow width. The inclusion of a flange simplifies installation in thin-walled housings.
Bearing Features
This series is particularly well-suited for encoders and stepper motors that require precise rotation within extremely limited axial space. Thanks to the excellent magnetic permeability and mechanical properties of the bearing steel, the series operates smoothly in electromagnetic environments without interfering with motor signals. Precise control of internal clearances ensures low heat generation during high-speed operation, effectively preventing premature grease failure.
