When used correctly, internal gears provide various advantages. One advantage is that the sliding effect is lessened. When the external gear and pinion gear have the same gear ratio and tooth length, the matching tooth surfaces of the internal gear and pinion gear are closer to the same length. As a result, the relative slip of the teeth is reduced inside the case. This brings up one of the benefits of employing internal gears. Friction is caused by one tooth sliding against another; because friction increases tooth wear, it is best to decrease the sliding action.

Just as an external gear is excavated out of a discus, the tooth profile is a reverse involute, which is a conjugate involute. In general, medium carbon steel is used for quenching and tempering, the carburized ring gear has a low modulus, and the gear is processed after heating by wire cutting.
