Planetary gearbox with 15:1 reduction and 700 N.m continuous torque
The GBX1600150553F is a straight-tooth planetary gearbox from Schneider Electric's GBX series, with a 160 mm outer diameter and a 15:1 reduction ratio. It delivers 700 N.m continuous output torque at 100 rpm and 30 °C, with a maximum intermittent torque of 1120 N.m under the same conditions. Maximum torsional backlash is 10 arcmin, and torsional rigidity is 41 N.m/arcmin — the gearbox holds position well under load for indexing or positioning applications.
Lifecycle status — obsolete, sourced through independent channels
No official successor or cross-reference is recorded from the manufacturer. The part is available through independent surplus and broker channels; quantities are lot-specific and confirmed at RFQ.
Mechanical ratings and operating envelope
Rated service life is 30,000 hours at 100 rpm and 30 °C, with the gearbox lubricated for life — no maintenance re-greasing required. Maximum axial force on the output shaft is 6000 N at 100 rpm for the 30,000-hour life, or 8000 N for a 10,000-hour duty cycle. Maximum radial force (applied at mid-shaft) is 4200 N for the longer life, 6000 N for the shorter. Ambient temperature range for operation is -25 to 90 °C, and the shaft output seal is rated IP54 — suitable for indoor or sheltered installations where dust and splash are present.
Efficiency and noise — 94 % and 70 dB
Efficiency is listed at 94 %, which is typical for a single-stage planetary gearbox at this ratio — most of the input power reaches the output, with losses mainly in gear mesh and bearing friction. Noise level is 70 dB at 1 m under no-load conditions — roughly the level of a vacuum cleaner, so in a machine enclosure or separate room it will not dominate the ambient noise floor.
