F68 Series Metric Miniature Flanged Bearings

This series encompasses ultra-miniature specifications with inner diameters ranging from 1 mm to 9 mm. Its core advantages lie in exceptional lightweight characteristics and space efficiency. Manufactured from high-quality bearing steel, the bearings feature an integral flange on the outer ring that effectively prevents axial displacement during high-speed operation, ensuring secure installation.

Bearing Features

Structurally, the F68 series utilizes an ultra-thin cross-section design with minimal frictional torque, making it ideal for applications requiring high rotational sensitivity, such as micro-motors, precision instruments, and clockwork mechanisms. Furthermore, the high hardness of the bearing steel provides excellent wear resistance, ensuring a long service life even under limited lubrication conditions. The installation process eliminates the need for complex housing designs, significantly simplifying the assembly of miniature equipment.
