Planetary gearbox, 5:1 reduction, 195 N.m continuous — now obsolete
The GBX1200050702F is a Schneider Electric planetary gearbox with a 5:1 reduction ratio, straight teeth, and a 120 mm housing diameter. It delivers 195 N.m continuous output torque at 100 rpm and 30 °C, with a peak of 312 N.m for short-duration loads. Efficiency is rated at 94 %, and the unit is lubricated for life — no scheduled oil changes. Service life is 30,000 hours at rated speed and temperature.
Load ratings and mechanical limits
Maximum radial force on the output shaft is 1500 N at 100 rpm for the 30,000-hour service life, or 2000 N for a 10,000-hour life. Axial force limits are 2100 N and 2800 N respectively. Torsional rigidity is 12 N.m/arcmin, and maximum torsional backlash is 8 arc.min — relevant for positioning accuracy in indexing or servo-feed applications. The shaft output seal carries an IP54 ingress protection rating, and the housing is black anodized aluminium with a C 45 steel shaft. Noise level at 1 m under no-load is 65 dB — a moderate acoustic signature for a straight-tooth planetary of this size.
Sourcing an obsolete gearbox — what to expect
Because the GBX1200050702F is obsolete, it is not available through Schneider Electric's standard distribution. We source it through independent surplus and broker networks — quantities are lot-specific and confirmed at RFQ. No official successor or form-fit-function replacement is recorded from Schneider Electric. If a direct drop-in is required, the BOM position should be reviewed against the original application's torque, ratio, and mounting envelope.
