Precision motion is not defined by the gear alone – it is defined by the system.
Many accuracy, vibration, and reliability problems in motion systems do not originate from the gear itself, but from the interaction between the gear, the coupling, and the mechanical structure in between. This engineering guide presents a system-level approach to selecting gears and couplings, helping designers move beyond catalog data and build motion solutions that remain accurate, stable, and reliable in real-world operation.
