Planetary gearbox, 160 mm, 25:1
The Schneider Electric GBX1600250554F is a straight-tooth planetary gearbox with a 160 mm outer diameter and a 25:1 reduction ratio. It delivers 700 N.m continuous output torque at 100 rpm and 86 °F (30 °C), with a maximum peak of 1120 N.m under the same conditions. Rated service life is 30,000 hours at 100 rpm and 30 °C, lubricated for life — no maintenance schedule for oil changes.
Torque, backlash, and load capacity
Maximum torsional backlash is 10 arc-min, and torsional rigidity is 41 N.m/arcmin — this pair defines the positioning repeatability for indexing or servo applications where lost motion matters. Maximum axial force Fa is 6000 N at 100 rpm for the full 30,000-hour life, or 8000 N for a 10,000-hour duty cycle. Maximum radial force Fr is 4200 N at mid-shaft for 30,000 hours, or 6000 N for 10,000 hours — both at 30 °C. Efficiency is 94 %, and noise level is 70 dB at 1 m under no-load — typical for a straight-tooth planetary of this size.
Construction and environment
Housing is black anodized aluminium; the output shaft is C45 steel. Shaft output seal is rated IP54, meaning splash protection but not submersion — suitable for dry indoor environments with occasional washdown mist. Operating ambient temperature range is -13 to 194 °F (-25 to 90 °C).
Obsolete — sourcing through independent channels
The GBX1600250554F is listed as obsolete by Schneider Electric. Available through independent surplus and broker channels — quantities are lot-specific and confirmed at RFQ. No pin-compatible drop-in replacement from Schneider has been published.
