Obsolete — last-time-buy sourcing reality
Schneider Electric lists the GBX1600120702F as obsolete. This planetary gearbox is sourced through independent surplus and last-time-buy channels. Quantities are lot-specific and confirmed at RFQ — no stock-holding claim is made here.
Torque ratings and service life at 100 rpm
Continuous output torque is 800 N.m (7080.6 lbf.in) at 100 rpm and 30 °C. Maximum output torque reaches 1280 N.m (11328.9 lbf.in) under the same conditions. Service life is rated at 30000 hours at 100 rpm and 30 °C. The gearbox is lubricated for life, so no field re-lubrication interval to schedule.
Shaft loading limits — axial and radial
Maximum axial force Fa is 6000 N at 100 rpm for the 30000-hour service life, or 8000 N for a 10000-hour life at 30 °C. Maximum radial force Fr is 4200 N at 100 rpm for 30000 hours, or 6000 N for 10000 hours, with the force applied at mid-distance from the output shaft.
Backlash, rigidity, and environmental limits
Maximum torsional backlash is 10 arc.min. Torsional rigidity is 41 N.m/arcmin — relevant for positioning accuracy in servo-driven indexing applications. Ambient temperature range for operation is -25 to 90 °C (-13 to 194 °F). The shaft output seal carries an IP54 rating, meaning splash protection but not washdown.
Efficiency and noise floor
Listed efficiency is 94 %. Noise level is 70 dB at 1 m, no-load — a straight-tooth planetary is inherently noisier than helical, so budget for enclosure attenuation if the application is sound-sensitive.
