Alpha Getriebebau SP-140-IS1-9 Precision Gearhead

The Alpha Getriebebau SP-140-IS1-9 Precision Gearhead (SP140IS19) is a size-140 SP+ high‑speed, low‑backlash planetary gearhead from Witt enstein alpha Getriebebau, designed to mount to servo motors and deliver precise torque with minimal backlash in automated systems. As part of the SP+ family, it emphasizes energy efficiency and robust construction for continuous operation in automation, robotics, CNC modules, packaging lines, and other precision-driven applications. SP+ gearheads are offered in one- and two-stage configurations with gear ratios ranging from 4:1 to 100:1, enabling a range of speed-torque combinations for diverse motion tasks. For the SP140 size, maximum input speed is up to 4,500 min-1 and nominal input speed is typically in the 2,500–4,200 min-1 range depending on the exact configuration, providing flexibility for varying servo motor controls. Output shaft options include smooth shafts, DIN 6885 Form A keyed shafts, or involute DIN 5480 profiles to fit a wide range of actuators. This model is well suited for robotics, pick-and-place systems, CNC modules, and automated assemblies where precise positioning, repeatability, and reliable life are critical, and where the SP+ design’s low backlash and efficient transmission help improve throughput and accuracy.
