Planetary gearbox, 16:1 reduction, 800 N.m continuous — what the ratings mean
The GBX1600160553F is a straight-tooth planetary gearbox from Schneider Electric's GBX series, with a 160 mm outer diameter and a 16:1 reduction ratio. It delivers a continuous output torque of 800 N.m at 100 rpm, and can handle a maximum output torque of 1280 N.m under the same conditions — that extra headroom matters for peak loads during acceleration or momentary jams. At 94 % efficiency, the gearbox loses only about 6 % of input power to friction and windage — a solid figure for a straight-tooth planetary, where the trade-off for lower cost versus helical gearing is usually a few points of efficiency and higher noise. The 70 dB noise level at 1 m, no-load, is typical for this class; in a machine enclosure it will be quieter.
Load ratings and service life — sizing for the application
Maximum radial force (Fr) at the output shaft is 4200 N for the full 30,000-hour life, or 6000 N if you accept a shorter 10,000-hour life. Maximum axial force (Fa) is 6000 N for 30,000 hours, 8000 N for 10,000 hours. Torsional rigidity is 41 N.m/arcmin — a stiffer gearbox means less windup under load, which matters for positioning accuracy in servo-driven axes. The shaft output seal is rated IP54, so it resists dust and splashing water — fine for most industrial environments, but not for washdown.
Obsolete — sourcing through independent channels
Schneider Electric lists the GBX1600160553F as obsolete. This gearbox is available through independent surplus and broker channels — quantities are lot-specific and confirmed at RFQ. For a BOM that needs this exact planetary gearbox, the sourcing path is a quoted-to-order request against the required quantity.
