Precision Flanged Drive Pin for Sewing Machine Motors
Tingfeng Hardware specializes in precision flanged drive pins manufactured with CNC machining processes using zinc plated carbon steel material. These components are specifically designed for sewing machine motors and industrial sewing equipment, featuring strict dimensional tolerance control for precise fit with motor output shafts and linkage mechanisms.
Product Overview
Flanged drive pins serve as critical connecting components between sewing machine motors and transmission mechanisms. Manufactured through precision CNC turning and end grinding processes, our products ensure excellent coaxiality and perpendicularity between flange face and pin shaft. Tight tolerance control guarantees optimal interference or clearance fit with mating holes, while zinc plated carbon steel provides both strength and corrosion resistance.
