These brass pinion gears are designed for use with smaller diameter 1.5mm motor shafts.  For example, a "slim-can" (FF-050) motor has a 1.5mm diameter shaft.  This pinion gear has 10 teeth (10T), a diameter of 5.5mm and is compatible with motors having a 1.5mm diameter shaft. 5.5mm pinion gears are generally designed for use with Crown (inline) gears; however, there are always exceptions.  For more information about compatible pinion / driven gear combinations and available gear ratios, please click the link below.


IMPORTANT:  Space constraints in cars where slim-can motors are often used may also limit your selection of crown gears.  The diameter of a crown gear will increase as the number of teeth increases.  While the Gear Ratio Chart shows all possible combinations, it is up to you to determine if a given crown gear will actually fit in your car.
