The APEX DYNAMICS AP142-040-S2-P2 is a premier heavy-duty, high-precision in-line planetary gearbox engineered by APEX DYNAMICS, INC. (Taiwan) – a world leader in high-performance servo motion transmission technology. This unit is configured with a dedicated custom motor adapter plate coded P0403300606 / AD-P90-M90-6, ensuring direct, seamless, and coaxial mounting onto Mitsubishi MELSERVO-J4 Series Medium Inertia AC Servo Motors model HG-SR352B (3.5 kW rated output, 2000 rpm rated speed, equipped with an electromagnetic holding brake).

The gearbox features case-hardened, precision-ground Helical Planetary Gears conforming to DIN 6 accuracy standards. Its helical gearing design maximizes tooth contact ratio and engagement surface area, delivering substantial continuous torque capacity, smooth power delivery, minimal acoustic emission, and minimized thermal buildup compared to conventional spur gears. Engineered with a 2-stage gear reduction ratio of 1:40 and certified P2 backlash class (≤ 7 – 9 arcmin), this model guarantees superior motion repeatability, high torsional rigidity, and outstanding shock-load resistance for heavy-duty servo axes. Enclosed in a rugged housing with IP65 ingress protection and lubricated for life with premium synthetic grease, it provides reliable, maintenance-free operation across industrial automation environments.
