The GBX1600050701F is a Schneider Electric planetary gearbox with straight teeth, 160 mm external diameter, and a 5:1 reduction ratio. It delivers a maximum output torque of 6372.5 lbf.in (720 N.m) at 100 rpm and 86 °F (30 °C), with a continuous output torque of 3982.8 lbf.in (450 N.m) under the same conditions. The 94 % efficiency figure means 6 % of input power is lost as heat inside the gearbox — relevant for thermal management in a sealed enclosure. Service life is rated at 30,000 hours at 100 rpm and 30 °C, with the gearbox lubricated for life, so no maintenance oil changes are needed over that span.
Mechanical limits — axial and radial load capacity
Maximum axial force Fa is 6000 N at 100 rpm for the full 30,000-hour service life, or 8000 N if the application accepts a shorter 10,000-hour life. Maximum radial force Fr is 4200 N at 100 rpm for 30,000 hours, or 6000 N for 10,000 hours, with the force applied at the midpoint of the output shaft. Torsional rigidity is 38 N.m/arcmin — this stiffness figure governs positioning accuracy under load. Maximum torsional backlash is 6 arc.min, which sets the lost motion in a reversing or positioning axis.
Sourcing reality — obsolete but available through independent channels
Schneider Electric lists the GBX1600050701F as obsolete. The part is sourced through independent surplus and broker channels — quantities are lot-specific and confirmed at RFQ. The gearbox carries IP54 protection at the shaft output, operates in ambient temperatures from -25 to 90 °C, and uses a black anodized aluminium housing with a C45 steel shaft. Noise level is 70 dB at 1 m under no-load conditions.
