The MF63 is a metric, flanged, deep-groove ball bearing with a compact 3mm bore, 6mm outer diameter, and 2.5mm width . This design supports moderate radial loads (dynamic load rating ~209 N or 208 N ) and is suited for high-speed operation (up to 71,000 or 81,000 rpm with grease lubrication). The integral flange simplifies mounting and positioning in compact machinery and precision instruments .
