WITTENSTEIN SP-075S-MF2-16-1E1-2S Planetary Gearbox

The WITTENSTEIN SP 075S-MF2-16-1E1-2S is a two-stage planetary gearbox from the alpha SP family, delivering a 16:1 reduction for servo-driven systems. Designed with MF2 mounting and the 1E1-2S option, it provides a robust output suitable for robotics, packaging lines, CNC axes, and material-handling applications where compact size and predictable torque are critical. The gearhead offers a maximum output torque around 126 N·m (T2α) and an emergency stop torque up to 250 N·m, supporting high-inertia loads and rapid stop scenarios. It accepts up to 8,500 min-1 input speed with a permissible average drive speed of 3,500 min-1, while the housing carries IP65 protection and is lubricated for life, with a maximum housing temperature of 90°C and noise emission ≤59 dB(A). Structural limits include a tilting moment of 236 N·m, axial force of 3,350 N and lateral force of 4,200 N, and a rotational inertia of about 0.55 kg·cm², contributing to predictable dynamic performance. Weight is typically documented around 4.0 kg for this variant. With its compact form and durable construction, the SP 075S-MF2-16-1E1-2S is designed to integrate with standard servo motors to deliver reliable torque amplification, smooth acceleration, and precise positioning in automated systems.
