The gearing is in the whole industrial manufacturing a very small part. It is like lathing, milling industries in Taiwan. We can find many jobbers. Because of its higher tech level than lathing and milling, the number of the gear jobbers is much less than lathing and milling. Because of the same reason, the gear jobbers who truly understand the gearing theories and can follow the technical trend and skill know-how are less.
