Lovejoy catalog number 69790400473 is an F3.5 series flanged elastomer coupling hub. This hub features a 3-1/2 inch bore with a 7/8 x 7/16 inch keyway, designed to mate with a corresponding F3.5E elastomeric sleeve to form a complete coupling assembly. The flanged design provides a robust connection for power transmission applications requiring high torque capacity and misalignment accommodation, typical in pump, fan, and compressor drives.
