What this 100:1 planetary gearbox delivers
The GBX1201001002F is a Schneider Electric planetary gearbox with a 100:1 reduction ratio, sized for applications needing high torque multiplication in a compact 120 mm diameter envelope. Continuous output torque is 260 N.m at 100 rpm; maximum intermittent torque reaches 416 N.m at the same speed, both rated at 30 °C ambient. Efficiency sits at 94 % — typical for a single-stage planetary with straight teeth, meaning about 6 % of input power is lost to gear mesh friction.
Torque, life, and load ratings — the numbers that matter
Service life is 30,000 hours at 100 rpm and 30 °C, lubricated for life — no maintenance oil changes, which simplifies installation in sealed or hard-to-access positions. Maximum axial force Fa is 2100 N for the 30,000-hour life target, or 2800 N if you accept a 10,000-hour service life at the same speed and temperature. Maximum radial force Fr is 1500 N for 30,000 hours, or 2000 N for 10,000 hours, both measured at mid-distance from the output shaft. Torsional rigidity is 12 N.m/arcmin — a measure of how much the output shaft twists under load; lower is stiffer, and 12 N.m/arcmin is typical for a planetary of this size class. Maximum torsional backlash is 14 arc.min — the angular play between input and output when reversing direction, important for positioning accuracy in indexing or servo applications.
Lifecycle reality — obsolete, sourced through independent channels
Available through independent surplus and broker channels; quantities are lot-specific and confirmed at RFQ. No stock-holding claim is made — each order is sourced per request.
Physical and environmental fit
Housing is black anodized aluminium, 120 mm external diameter; shaft material is C45 carbon steel. Shaft output IP54 protection — suitable for indoor industrial environments with dust and splash exposure, but not for washdown or submerged service. Noise level is 65 dB at 1 m under no-load — quiet enough for operator-adjacent installations without enclosure attenuation.
