ZPLF40 Low-Backlash Precision Right Angle Planetary Gearbox (≤8 arcmin) for 40mm Servo Motor

This ZPLF40 low-backlash precision right-angle planetary gearbox is engineered for 40 mm servo motors, featuring a space-saving 90-degree design with a built-in input coupling that accepts a Φ8 mm diameter input shaft and a maximum 25mm 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 ≤8 arcmin (single-stage) or ≤12 arcmin (two-stage), with reduction ratios from 3:1 to 100:1 and rated output torque of 9–15 N·m depending on the ratio. It handles a rated input speed of 3,000 RPM (max. 6,000 RPM) and loads of 165 N radial / 135 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 40 mm 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.
