Internal Gears

Description

Our internal gears are spur gears that turn “inside out”. In other words, cut the teeth into the inner diameter while the outer diameter remains smooth. This design allows the drive pinion to rotate inside the gear, enabling cleaning operations. These gears are for light-duty applications and are only available in brass. When choosing a matching spur gear, always remember that the difference in the number of teeth between the internal gear and the pinion should not be less than 15 (14 1/2° PA) or 12 (20° PA).
