What this 25:1 planetary gearbox delivers
The GBX0600251001F is a 60 mm-diameter planetary gearbox with a 25:1 reduction ratio, designed for applications needing precise speed reduction and torque multiplication in a compact footprint. Its straight-tooth geometry keeps backlash under 20 arcmin, which matters for positioning stages or indexing tables where lost motion translates directly to position error. Continuous output torque is 40 N.m at 100 rpm, with a peak of 64 N.m available for short-duration loads. The 94 % efficiency means only 6 % of input power is lost as heat — a meaningful number when sizing the upstream motor and drive for a duty cycle that runs near the continuous torque limit.
Lifecycle reality — obsolete, sourced to order
Schneider Electric lists this gearbox as obsolete. The part is available through independent distribution channels; quantities are confirmed at RFQ, and pricing is quoted against the specific BOM line.
Mechanical limits that govern the fit
The gearbox is rated for 30,000 hours of service life at 100 rpm and 30 °C ambient — a standard industrial duty target. The shaft output carries an IP54 seal, so it handles dust and splash but not washdown. Lubrication is sealed for life, which eliminates maintenance intervals but also means the gearbox cannot be re-greased in the field. Maximum axial force on the output shaft is 450 N at the rated life, and maximum radial force is 340 N when applied at mid-shaft. Torsional rigidity is 2.5 N.m/arcmin — a stiffness figure that tells you how much wind-up to expect under load; for a 40 N.m continuous torque, the elastic twist is roughly 16 arcmin before the backlash gap is taken up. The housing is black anodized aluminium, the shaft is C45 steel, and the operating ambient range spans -25 to 90 °C. Noise at 1 m under no-load is 58 dB — quiet enough for a lab or assembly cell but not silent; if the application is in a noise-sensitive area, the straight-tooth profile will whine more than a helical gearbox would.
