Planetary gearbox, 160 mm frame, 15:1 reduction — torque and backlash limits
The GBX1600150702F: This is a Schneider Electric GBX-series planetary gearbox with a 160 mm outer diameter housing, straight-tooth gearing, and a 15:1 reduction ratio. The continuous output torque is 700 N.m at 100 rpm (30 °C ambient), with a maximum intermittent torque of 1120 N.m at the same speed. The 10 arcmin maximum torsional backlash places it in the standard-precision class — adequate for positioning conveyors, rotary indexing tables, and general motion axes where sub-arcmin repeatability is not required. For applications needing tighter positioning, a lower-backlash variant from the GBX family would be the better fit.
Torque, life, and overhung load limits at 100 rpm
Rated service life is 30,000 hours at 100 rpm and 30 °C, with the gearbox lubricated for life — no maintenance re-greasing interval to schedule. The 94 % efficiency means 6 % of input power is lost as heat, which the anodised aluminium housing (black) dissipates; at 700 N.m continuous output, the thermal loss is manageable in a ventilated enclosure. Maximum radial force (Fr) at the output shaft mid-point is 4200 N for the full 30,000-hour life, or 6000 N if you accept a reduced 10,000-hour service life. Maximum axial force (Fa) is 6000 N for 30,000 hours, 8000 N for 10,000 hours. These limits govern belt-drive or chain-sprocket loads directly mounted on the output shaft. Torsional rigidity is 41 N.m/arcmin — the stiffness constant for calculating wind-up under load. The shaft is C45 steel; the output seal is rated IP54, so the gearbox is splash-resistant but not washdown-rated.
Obsolete — sourcing through independent channels
Schneider Electric has marked the GBX1600150702F as obsolete. For a BOM that requires this exact frame size and ratio, the procurement path is a confirmed quote from the independent distribution network — no factory lead time applies.
