The continuous output torque is 110 N.m at 100 rpm and 30 °C, with a maximum intermittent torque of 176 N.m at the same speed — the margin above continuous is the peak overload the gear train can handle before the service life drops below the 30000-hour baseline. Efficiency is 94 %, typical for a single-stage planetary with straight teeth; the remaining 6 % is friction loss in the gear mesh and bearing drag, which shows up as heat in the housing. The 80 mm black anodized aluminium housing dissipates that heat — no external cooling needed at this torque level. ## Backlash, rigidity, and the load limits that govern the application Maximum torsional backlash is 9 arc.min — this is the angular play between input and output when the direction reverses. For a positioning axis that indexes bidirectionally, that 9 arc.min shows up as lost motion at the load; if the application needs tighter repeatability, a lower-backlash gearbox (3 arc.min or less) would be the alternative. Torsional rigidity is 6 N.m/arcmin, meaning the shaft winds up 1 arcmin for every 6 N.m of applied torque — this stiffness matters when the load inertia is high and the servo loop gains are aggressive. The shaft output seal is rated IP54, so the gearbox handles dust and splashing water at the output side — the motor side is open to the mounting flange, so the IP rating does not extend to the input. Maximum axial force on the output shaft is 1200 N for a 10000-hour life at 30 °C, dropping to 900 N for the full 30000-hour service life. Radial force at mid-shaft is 950 N for 10000 hours, 650 N for 30000 hours. These are the limits that govern belt-drive or direct-coupling loads — exceed them and the bearing life shortens faster than the gear tooth wear. ## Obsolete — sourcing the GBX0800050553F through independent channels Schneider Electric has marked the GBX0800050553F as obsolete. The gearbox is sourced through independent surplus and broker channels — quantities are lot-specific and confirmed at RFQ. Availability and current pricing are checked at quote time against the BOM quantity. The gearbox is lubricated for life — no oil-change interval to track. Noise level at 1 m under no-load is 60 dB, roughly the sound of a quiet office — the straight-tooth mesh is inherently noisier than helical, so this is the acoustic floor; under load the noise rises with torque.","metaTitle":"Schneider Electric GBX0800050553F Planetary Gearbox, 5:1","metaDescription":"Schneider Electric GBX0800050553F planetary gearbox, 80 mm, 5:1 reduction, 110 N.m continuous torque, 94% efficiency.
