The GBX0400201001F is a 40 mm diameter planetary gearbox with a 20:1 reduction ratio, delivering 20 N.m continuous output torque at 100 rpm and 30 °C. That continuous rating is the number to size against — the maximum intermittent torque is 32 N.m, but the service life of 30,000 hours at rated load is tied to the continuous figure. Straight-tooth planetary gearing means it's efficient — 94 % — but the torsional backlash is 28 arc.min maximum. That backlash figure is the one to check if the axis reverses direction under load; for positioning applications, the repeatability starts at that play.
Mechanical limits — shaft loads and mounting envelope
The output shaft accepts 200 N axial force (Fa) and 200 N radial force (Fr) when the load is applied at mid-shaft distance, both at 100 rpm for a 10,000-hour service life. For the full 30,000-hour rating, those drop to 160 N each — plan the overhung load budget accordingly. Torsional rigidity is 1.1 N.m/arcmin, which tells you the wind-up under load. The housing is black anodized aluminium, 40 mm diameter, with IP54 protection at the shaft output — sealed against dust and splash, not submersion. Ambient operating range is -25 to 90 °C. Lubricated for life — no maintenance oil changes. Noise level is 55 dB at 1 m, no-load, which is quiet enough for a lab or light industrial bench but not silent for a clean-room spec.
Lifecycle reality — obsolete, sourced through independent channels
Schneider Electric lists the GBX0400201001F as obsolete. The spec table above carries the full mechanical ratings; confirm the shaft dimensions and mounting interface against your existing axis before committing.
