Torque envelope and load ratings
The GBX1200050844D: Continuous output torque is 195 N.m; the maximum output torque reaches 312 N.m — the gap between these figures defines the overload margin for intermittent peak loads without exceeding the gearbox's mechanical limit. Service life is rated 30,000 hours at 100 rpm and 30 °C; the axial and radial force ratings at that life are 2100 N (Fa) and 1500 N (Fr) respectively, both measured at 100 rpm and mid-span on the output shaft.
Accuracy and stiffness specs
Maximum torsional backlash is 8 arc.min — this sets the positioning repeatability floor for the load side. Torsional rigidity is 12 N.m/arcmin, meaning each 12 N.m of torque twist the output shaft by one arc-minute. The straight-tooth planetary design delivers 96 % efficiency across the ratio, with a noise floor of 65 dB at 1 m under no-load conditions.
Construction and integration
Housing is black anodized aluminium, 120 mm external diameter; shaft material is C 45 steel. The gearbox is lubricated for life and can be mounted in any position. Shaft output seal is rated IP54 — suitable for dry indoor environments with dust and light splash exposure, but not for washdown or submerged service. Operating ambient temperature range spans -25 to 90 °C, covering most industrial enclosure conditions without active cooling.
Lifecycle and sourcing
Schneider Electric lists this part as obsolete. No official successor or cross-reference is recorded from the manufacturer. Available through independent surplus and broker channels; quantities are lot-specific and confirmed at RFQ. No pin-compatible or footprint-equivalent direct replacement is documented.
