DEVELOPMENTS

  • Propeller Shaft
    EG

    1. PROPELLER SHAFT

    Propeller shaft is an axis that transmits power from vehicle’s engine and transmission to the axle and transmits high-speed rotation and high-speed torsional force.  It is used for high-speed rotation driving axle of FR(Front engine rear drive axle) car, 4x4, commercial vehicles, aircraft, shipbuilding, industrial machinery.

    PROPELLER SHAFT

    2. The 3rd generation
    propeller shaft

    Completed the development of WOOSHIN EMC’s third generation propeller shaft.  Achieved low weight, low noise, low vibration through unification of modules.
