32:1 planetary gearbox — 800 N.m continuous, 1280 N.m peak
The GBX1600320553F is a Schneider Electric planetary gearbox with straight teeth, 160 mm outer diameter, and a 32:1 reduction ratio. Continuous output torque is 7080.6 lbf.in (800 N.m) at 100 rpm and 86 °F (30 °C); maximum output torque reaches 11328.9 lbf.in (1280 N.m) under the same conditions. Maximum torsional backlash is 10 arc.min — this is a standard-precision grade, not a zero-backlash unit. For positioning applications requiring tighter repeatability, a lower-backlash variant in the GBX family would be the right call.
Rated life and thermal limits — 30000 hours at full load
Service life is 30000 hours at 100 rpm and 30 °C ambient, with the gearbox lubricated for life — no scheduled oil changes. Ambient temperature range for operation is -13 to 194 °F (-25 to 90 °C). Maximum axial force Fa is 6000 N at 100 rpm for the full 30000-hour life, or 8000 N for a 10000-hour duty cycle. Maximum radial force Fr is 4200 N at mid-span on the output shaft for 30000 hours, or 6000 N for 10000 hours. These are the load limits that govern bearing life — exceeding them shortens service life proportionally.
Obsolete — sourced through independent channels
Schneider Electric lists the GBX1600320553F as obsolete. Available through independent surplus and broker channels. Quantities are lot-specific and confirmed at RFQ; pricing and lead time are quoted against the BOM quantity. No stock-holding claim — sourced per order.
Efficiency and noise — 94 % at 70 dB
Rated efficiency is 94 %, typical for a single-stage planetary with straight teeth at this ratio. Noise level is 70 dB at 1 m, no-load — within range for a 160 mm-frame gearbox in a machine-tool or conveyor drive application. Shaft output seal is rated IP54 — suitable for indoor environments with dust and splash exposure, but not for washdown or submerged service.
