Transmits torque between parallel shafts to provide rotational power to another part of a motorized system
Pressure angle of 14.5 degrees for a higher contact ratio between gears, resulting in quieter operation than larger pressure angles
Diametral pitch of 16 for applications requiring a balance between transferring torque and controlling changes in speed and direction of rotation with precision
Low carbon steel (.2 percent carbon) for applications where the hardness and strength of higher levels of carbon are not needed to transmit torque and motion
