APEX Dynamics PEII120-016 Precision Gearhead 16 to 1

PEII120-016 is Apex Dynamics' inline planetary gearbox delivering a 16:1 reduction in a compact 120 mm frame for high-torque servo applications. The PEII family features a steel housing with an aluminum output and motor-adapter flange, a round B14 flange for broad motor compatibility, and an output shaft with a key to simplify mounting. For the 120 mm size, the nominal torque is 42 Nm, with 2‑stage backlash typically around 8–10 arcminutes and high efficiency generally rated at about 94% or higher under load. Built with precision-bonded housings and laser-welded pinions to maximize concentricity and stiffness, this gearhead provides repeatable, accurate motion in robotics, CNC axes, and other automated equipment that demand compact form factor and reliable torque density.
