Bosch Power Tools 2606316902 Pinion

The Bosch Power Tools 2606316902 Pinion is a tiny but essential part of the power transmission of the Bosch power tools. It’s a gear with teeth that cogs into other gear, transferring the rotational motion and torque from motor to the working mechanism of the tool. The motor shaft is equipped with the pinion gear, which mates with large gears inside the gearbox of the tool. The rotational motion and torque essential by the motor as it spins is transmitted to the larger gears via the pinion gear, which are in turn in contact with the tools cutting, drilling or sanding mechanism. The gear ratio of the pinion to any of the larger gears set the tool speed and torque output.
