ZPLF120-MB Low-Backlash Precision Right Angle Planetary Gearbox (≤7 arcmin) for 110mm Servo Motor

This ZPLF120-MB low-backlash precision right-angle planetary gearbox is engineered for 110 mm servo motors, featuring a space-saving 90-degree design with a built-in input coupling that accepts a Φ19 mm diameter input shaft and a maximum 60mm long input shaft. Its right-angle configuration allows the output shaft to be routed conveniently where an inline gearbox would be difficult to mount. The gearbox delivers low backlash of ≤7 arcmin (single-stage) or ≤12 arcmin (two-stage), with reduction ratios from 3:1 to 100:1 and rated output torque of 90–240 N·m depending on the ratio. It handles a rated input speed of 3,000 RPM (max. 6,000 RPM) and loads of 2,000 N radial / 1,400 N axial, operating at ≤55 dB with IP65 protection, permanent lubrication, a 20,000-hour lifespan, and an ambient temperature range of -40°C to +150°C. Its square flange, right-angle layout, and low-backlash gearing make it well suited to space-constrained precision axes in CNC machines, industrial robotics, automated production lines, packaging machinery, laser processing equipment, and medical or semiconductor handling systems where efficient torque multiplication and flexible shaft routing are required.
