Obsolete — sourcing through independent channels
Schneider Electric lists the GBX1600120701F as obsolete. The part is available through independent surplus and broker channels; quantities are lot-specific and confirmed at RFQ.
Torque ratings and duty cycle
Rated for a continuous output torque of 800 N.m at 100 rpm and 30 °C ambient. The maximum intermittent torque reaches 1280 N.m under the same conditions. The 12:1 reduction ratio means the input speed is twelve times the output speed; torque multiplication follows the ratio minus efficiency losses. Service life is specified at 30,000 hours at rated load and speed. The gearbox is lubricated for life — no field re-greasing interval to schedule.
Mechanical constraints — backlash, forces, and environment
Maximum torsional backlash is 10 arc.min — typical for a straight-tooth planetary stage at this size. For applications requiring lower lost motion, a precision-geared alternative would be needed. Maximum axial force Fa is 6000 N at 100 rpm over the 30,000-hour life, or 8000 N for a reduced 10,000-hour life. Maximum radial force Fr is 4200 N at mid-span on the output shaft for the 30,000-hour rating, 6000 N for the 10,000-hour rating. These force limits govern overhung load capacity on the output shaft. Ambient temperature range for operation is -25 to 90 °C. The shaft output seal is rated IP54 — protected against dust ingress and splashing water, but not submersion or high-pressure washdown.
Efficiency and noise
Efficiency is listed at 94 % — typical for a single-stage planetary with straight teeth. Noise level is 70 dB at 1 m, no-load.
