Pinion

The pinion gear is a small cylindrical gear designed to mesh with a larger gear or rack. It serves as the primary driver in many mechanical systems, converting rotational motion into linear movement or modifying speed and torque ratios. Typically crafted from hardened steel or durable alloys, it ensures reliable performance under high stress. Widely used in automotive steering, power tools, and industrial machinery, this gear is essential for precise motion control and efficient power transmission in compact assemblies.
