HB812R Bronze Helical GearBoston Gears stock helical gears are manufactured in both right and left handed configurations with an industry standard 45 helix angle to transmit motion and power between non intersecting shafts that are parallel or at 90 to each other. For parallel shaft operation, helical gears with opposite hand helix angles are required. For shafts at 90, a same hand helix angles must be used. For parallel shaft applications, the overlapping tooth contact of our
