The GBX0800161401F is a straight-tooth planetary gearbox with an 80 mm housing diameter and a 16:1 reduction ratio. The continuous output torque is 120 N.m at 100 rpm and 30 °C — this is the sustained load the gearbox can transmit without exceeding the 30,000-hour service life target. Maximum output torque reaches 192 N.m at the same speed and temperature, covering short-duration peak loads during acceleration or shock events. The 14 arc.min maximum torsional backlash is the angular play at the output shaft under reverse load — relevant for positioning accuracy in indexing or pick-and-place applications where cumulative backlash affects repeatability. Efficiency is listed at 94 %, meaning 6 % of input power is lost as heat in the gear mesh and bearings. For a 120 N.m output at 100 rpm, the input power required is roughly 1.34 kW; the 80 W thermal loss stays within the housing's dissipation capacity at the rated ambient range of -25 to 90 °C.
Sourcing and lifecycle — obsolete, quoted to order
Schneider Electric lists the GBX0800161401F as obsolete. The gearbox is available through independent surplus and broker channels; quantities are lot-specific and confirmed at RFQ. For a project or MRO buy, the key specs to match against the BOM are the 80 mm housing diameter, 16:1 ratio, 120 N.m continuous torque, and the IP54 shaft output seal. The gearbox is lubricated for life — no maintenance oil changes are required over the 30,000-hour service life at rated load.
Mechanical integration — shaft loads and mounting
The output shaft is made of C45 steel. Maximum radial force Fr is 650 N applied at mid-distance from the output shaft for a 30,000-hour life at 100 rpm and 30 °C; for a 10,000-hour life the limit rises to 950 N. Maximum axial force Fa is 900 N for 30,000 hours and 1200 N for 10,000 hours at the same conditions. The housing is black anodized aluminium. The IP54 rating at the shaft output means the gearbox is protected against dust ingress and splashing water — suitable for indoor industrial environments with occasional washdown, but not for high-pressure or submerged service. Noise level is 60 dB at 1 m under no-load conditions — this is the acoustic baseline from the gear mesh and bearings. Under load the noise increases with torque and speed; the straight-tooth design is inherently noisier than helical, so acoustic enclosures may be needed in sound-sensitive areas.
