Product Features

  • 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 20 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

Product Details


Product Description

The Boston Gear low carbon steel spur gear with 14.5-degree pressure angle (PA) and a diametral pitch (DP) of 20 transmits torque between parallel shafts to provide rotational power to another part of a motorized system. It has a 14.5-degree pressure angle for a higher contact ratio between gears than larger pressure angles, resulting in quieter operation, and a 20-diametral pitch for applications requiring a balance between transferring torque and controlling changes in speed and direction of rotation with precision. This spur gear, which can mesh only with spur gears that have the same pressure angle and diametral pitch, is made of 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. This Boston Gear spur gear is suitable for use in a variety of commercial and industrial applications, such as construction equipment, aeronautics, conveyors, and manufacturing equipment, among others.

Spur gears, the most common gear type, have a circular or cylindrical shape with teeth bordering the outer perimeter and are used for transmitting rotational torque and motion between parallel rotating shafts. A spur gear's pressure angle (PA), diametral pitch (also called DP or pitch), and its material are important factors to consider when purchasing. Gears come in several types for use in different power transmission configurations and for different applications, including bevel and miter gears (for rotating shafts perpendicular to each other), change gears (to increase or decrease torque and speed), helical gears (for high rates of rotational speed), internal gears (where one gear is nested inside the other), rack and pinion gears (for turning rotational motion into linear motion), and worm gears (for perpendicular shafts in tight spaces and quiet operation). Gears are suitable for use in the agriculture, automotive, construction, mining, and packaging industries, and can be found in a variety of machines, including bicycles, automobiles, and elevators, among others.

Boston Gear manufactures a variety of gear drives, variable speed drives, clutches, and the components that comprise these systems including sprockets and bearings. Their manufacturing designs, production, and inspection meet International Organization for Standardization (ISO) standards for quality assurance. The company, founded in 1877, is headquartered in Charlotte, NC.
