QRC P (IEC) series is a foot-mounted helical gear reducer designed with an IEC-standard motor interface, enabling direct mounting of IEC motors for fast and universal integration. As part of the QRC modular helical gearbox family, the QRC P model features precision-ground helical gears, carburized and hardened tooth surfaces, and a rigid aluminum housing, ensuring smooth transmission, long service life, and low operational noise.

Its foot-mounted base (P type) provides strong structural stability, making it suitable for long-term continuous-duty applications. The modular design supports a wide combination of gear ratios, output shaft options, and motor mounting configurations, allowing users to adapt the gearbox easily to diverse industrial requirements.

The QRC P (IEC) series is ideal for textile machinery, ceramic equipment, food production lines, packaging systems, logistics conveyors, plastics machinery, and various automation environments.
