The concrete mixer pinion gear is one of the important components in the machine’s power transmission system. It is responsible for transferring rotational power from the driving shaft to the mating gear. In geared concrete mixers, proper engagement between the pinion and the mating gear ensures efficient power transmission and uniform drum rotation.

Manufacturing quality, material, and tooth precision are very important, as this component is constantly subjected to pressure and friction during operation. High-quality pinion gears are usually made of steel or alloy steel to provide suitable resistance against wear and pressure.
