Products > Spur Gears
While widely known for our bevel gear products, Arrow is also a leading supplier of spur gears. A spur gear has a cylindrical pitch surface with teeth that are parallel to the axis.
Arrow began robust investment in spur gear technologies over 30 years ago. Today, Arrow is equipped with a full range of advanced machine tools for the shaping, hobbing, grinding, and inspection of spur gears. Arrow’s spur gear products are now utilized in a wide range of both aerospace and commercial applications.
Arrow’s size range and capabilities for Spur Gears are provided in the list below.
Maximum Pitch Diameter – 36”
Diametral Pitch – 3.0 – 48
Face Width – 13.0
Unground Tooth – AGMA Q9
Ground Tooth – AGMA Q13
Pump gears are similar to spur gears in their geometry. However, pump gears are not used to transmit power between shafts. Instead, they are used for the positive displacement of fluid in pumping applications - most commonly for fuel systems. The benefit of using pump gears in this application over other methods is the precise volume of fluid that is displaced during each revolution.
