      JK-Gearbox for industrial applications
      
                    
      The JK series is a bevel cylindrical gear transmission device with 2, 3, and 4 stages of reduction, and the input shaft is perpendicular to the output shaft. The cylindrical gears are designed as helical gears, while the bevel gears are spiral bevel gears. All gears are made of advanced alloy steel, carburized and quenched before gear grinding.
