SPN..L

The SPN planetary reducer is a widely used industrial drive component that reduces motor speed while increasing output torque. Its name derives from the planetary motion of its gear train, which resembles the movement of the solar system. This series offers various input and output configurations and is available in multiple mounting styles, including foot and flange types.
