Spur gears are widely accepted as the most efficient type of gearing solution, when the application of transmitting power and uniform rotary motion from one parallel shaft to another is required. Determined by the center distance, spur gears create a steady functioning speed drive. This drive speed can be decreased or increased by the variable number of teeth that exist in the driving gear.

Several of our custom spur gears have been used in gear train applications - where multiple gears are required to have the same pressure angle and diameter pitch. They are available in plastic, non-metallic, brass, steel and cast iron. In addition ,these parts are manufactured many style types: plain, web, web with lightening holes, and web with spokes. Many are available with or without hubs.
