Max. Running torque 10.0Kgf-cm 20.0Kgf-cm 50Kgf-cm 50Kgf-cm 50Kgf-cm
Max. Gear breaking torque 20.0Kgf-cm 60.0Kgf-cm 150Kgf-cm 150Kgf-cm 150Kgf-cm

How to calculate the motor with gearbox output specs?
1. Output Speed(No-load)=Motor Speed(No-load)/Reduction Ratio
2. Output Torque=Motor Torque*Reduction Ratio*Gearbox Efficiency
 
e.g.: 
PG28BL28126000-21.5K
1. Output Speed(No-load)=6000/21.5=279RPM
2. Output Torque=80.7*21.5*81%=
1405.3g.cm≈1.4kg.cm=0.14Nm (Should not be higher than Max. Gear Running Torque)
