The APEX DYNAMICS AB090-005-S2-P2 is a premier high-precision in-line planetary gearbox belonging to the flagship AB Series engineered by APEX DYNAMICS, INC. (Taiwan) – a globally recognized benchmark in servo motion control gear technologies. This unit is equipped with a dedicated motor adapter plate coded P0401300305, ensuring direct, seamless, and coaxial mounting onto Mitsubishi MELSERVO-J4 Series Low Inertia AC Servo Motors model HG-KR73 (750W / 0.75kW rated power, 80 mm flange footprint).

The AB Series is distinguished by its case-hardened, precision-ground Helical Planetary Gears conforming to DIN 6 accuracy standards. This helical gearing geometry maximizes tooth contact surface, delivering substantial continuous torque capacity, ultra-smooth mechanical engagement, and minimal operating noise and thermal generation compared to conventional spur gears. Engineered with a single-stage reduction ratio of 1:5, certified P2 backlash class (≤ 5 arcmin), and a transmission efficiency exceeding 97%, it provides outstanding positional accuracy and repeatability for servo motion control. Encased in a rugged stainless steel housing with IP65 ingress protection and lubricated for life with synthetic grease, it provides completely maintenance-free operation across industrial automation environments.
