Continuous vs. peak torque is the number that decides shaft sizing on the driven machine: this gearbox is rated 450 N.m continuous and 720 N.m maximum output torque, so a servo or stepper application must keep the RMS load below 450 N.m to stay within the rated service life. ## Efficiency, backlash, and the noise envelope Efficiency is listed at 96 %, which is the expected figure for a planetary stage with straight-cut teeth; this leaves roughly 4 % of input power as heat at full load, and is what sets the thermal budget for the gearbox housing in enclosed cabinets. Maximum torsional backlash is 6 arc.min — adequate for general motion and positioning where a small lost-motion band is tolerable, but tighter applications (precision indexing, registration against a master encoder) need to budget the backlash into the position loop. Acoustic signature is 70 dB at 1 m under no-load conditions, the value most likely to be quoted on a factory floor noise survey; straight-tooth geometry is the reason it sits above helical alternatives. ## Shaft loads, service life, and mounting envelope Maximum radial force Fr is 4200 N at 100 rpm with the load applied at mid-distance from the output shaft over the rated 30000 h service life, and rises to 6000 N if the design only requires 10000 h at 30 °C — i.e. the radial load budget and the service-life target are coupled, not independent. Maximum axial force Fa is 6000 N at 100 rpm over 30000 h, or 8000 N over the shorter 10000 h horizon — a thrust-bearing or ballscrew-driven load needs to be checked against both figures before specifying. Service life is rated at 30000 h at 100 rpm and 30 °C; the gearbox is lubricated for life, so there is no scheduled oil change to plan into the maintenance schedule, but ambient temperature and duty cycle derate that figure above the 30 °C reference. The housing is black anodized aluminium and the shaft is C 45 steel, with any-position mounting and an IP54 rating at the shaft output — so the gearbox drops into a typical indoor panel or machine base without a sealed enclosure, but shaft-side splash zones still need a guard. ## Compatibility, inertia, and lifecycle status Compatibility code is GBX, meaning it mates with the GBX-family servo and stepper input stages; the gearbox moment of inertia is 4.63 g.cm², which is the figure to feed into the drive sizing calc alongside the load inertia.","metaTitle":"Schneider Electric GBX1600081383D planetary gearbox, 8:1","metaDescription":"GBX1600081383D planetary gearbox, Ø 160 mm, 8:1 reduction, 450 N.m continuous / 720 N.m peak, 96 % efficient.
