Our products are used in automotive and engineering industries. Helical gears have long and strong teeth. They can carry heavy load because of the greater surface contact with the gear teeth. Our helical gears are quieter with less vibration. One interesting thing about helical gears is that, if the angles of the gear teeth are correct, they can be mounted on perpendicular shafts, adjusting the revolving angle by 90 degrees.
