Planetary gearbox for precision motion — 20:1 reduction, 44 N.m continuous
The GBX0600200584D is a straight-tooth planetary gearbox in the GBX series, 60 mm outer diameter, delivering a 20:1 reduction ratio. Continuous output torque is 44 N.m, with a peak of 70 N.m available for intermittent loads — the margin matters if your application sees occasional overloads during acceleration or reversing. Efficiency sits at 94 %, which keeps thermal rise manageable in a compact anodized aluminium housing. Noise is 58 dB at 1 m under no-load — quiet enough for lab or light industrial environments where operator exposure is a concern.
Torque, backlash, and service life — the numbers that govern the fit
Maximum torsional backlash is 25 arc.min — this is the lost motion at the output when reversing direction. For indexing or positioning applications where repeatability matters, that figure sets the floor for achievable accuracy. Torsional rigidity is 2.5 N.m/arcmin, so the gearbox resists wind-up under load. Service life is rated 30,000 hours at 100 rpm and 30 °C ambient. The gearbox is lubricated for life — no maintenance interval to schedule. Axial force capacity is 450 N at 100 rpm for the full 30,000-hour life, or 600 N if you accept a shorter 10,000-hour window. Radial force at mid-shaft is 340 N (30,000 h) or 500 N (10,000 h). These force limits are the ones that bite if the output is belt-driven or overhung. Operating ambient range is -25 to 90 °C, and the shaft output seal is rated IP54 — fine for dry indoor use but not for washdown. Mounting position is any orientation, which simplifies layout in a tight panel or machine frame.
