Miniature thrust ball bearings, including the F and FM series, are designed for high-precision applications with bore sizes typically under 10mm. These micro-sized components are engineered to provide smooth axial support in space-constrained environments such as dental drills, high-end optical equipment, and miniature motors. Despite their small size, they maintain high accuracy and low friction under axial load.
