80 mm planetary, 15:1 — torque and life ratings
The GBX0800150854G is a straight-tooth planetary gearbox from Schneider Electric's GBX series, 80 mm outer diameter, with a 15:1 reduction ratio. It delivers 110 N.m continuous output torque at 100 rpm and 30 °C, with a maximum of 176 N.m under the same conditions. Rated service life is 30,000 hours at 100 rpm and 30 °C at continuous torque — a solid baseline for sizing in conveyor, indexing, or positioning axes where the duty cycle keeps the gearbox within its thermal envelope.
Efficiency, noise, and stiffness — what the numbers mean
Listed efficiency is 94 %, which is typical for a single-stage planetary with straight teeth. That 6 % loss shows up as heat in the housing; at 110 N.m and 100 rpm the thermal input is about 70 W, well within the black anodized aluminium housing's dissipation capacity. Noise level is 60 dB at 1 m, no-load — roughly the hum of a quiet office. Under load the straight-tooth mesh will be louder than a helical, but the 60 dB figure gives a baseline for enclosure sound-proofing estimates. Torsional rigidity is 6.5 N.m/arcmin, meaning a 6.5 N.m load twist the output shaft by one arc-minute. For servo positioning this stiffness determines the windup error under acceleration; paired with a 14 arc-min maximum backlash, the gearbox suits moderate-precision indexing rather than sub-arcminute contouring.
Sourcing reality — obsolete, quoted to order
Schneider Electric lists the GBX0800150854G as obsolete. Available through independent surplus and broker channels.
Mounting and environmental fit
Mounts in any position — the gearbox is lubricated for life, so no vent or oil-level orientation is needed. Shaft output seal is rated IP54, which keeps out dust and light splash but is not rated for pressurized washdown. The C 45 steel shaft handles radial loads up to 650 N at 100 rpm (mid-span, 30,000-hour life) and axial loads up to 900 N under the same duty.
