HPX60 Helical Planetary Gearbox ≤3 arcmin for 57/60mm Stepper Motor/BLDC Motor

This HPX60 helical planetary gearbox is engineered for 57/60 mm (NEMA 23/24) stepper and BLDC motors, featuring a space-saving inline design with a built-in input shaft coupling that accommodates a Φ14 mm motor shaft up to 33 mm long and a Φ16 mm keyed output shaft. Its helical gearing delivers exceptionally low backlash of ≤3 arcmin (single-stage) or ≤5 arcmin (two-stage), with reduction ratios from 3:1 to 100:1, rated output torque of 22–45 N·m, and transmission efficiency of 97% (single-stage) or 94% (two-stage). The gearbox handles a rated input speed of 3,000 RPM (max. 6,000 RPM) and loads of 1,530 N radial / 630 N axial, operating at ≤55 dB with IP65 protection, lifetime lubrication, a 20,000-hour lifespan, and an ambient temperature range of -20°C to +150°C; the single-stage version measures 72.5 mm in length and 1.1 kg, while the two-stage version is 101.5 mm and 1.4 kg. Its compact 60 mm frame, IP65 sealing, and helical low-backlash design make it well suited to precision motion axes in CNC routers and engravers, automated pick-and-place systems, packaging machinery, laser processing equipment, and industrial robotics requiring smooth, quiet operation and accurate torque multiplication from a 57/60 mm motor platform.
