Sized for 800 N·m continuous, peaks to 1280
The GBX1600201083D: Backlash is held to 10 arc.min maximum and torsional rigidity lands at 41 N.m/arcmin, which is what keeps a positioning axis from hunting at the coupling under reversing load (cite:,).
Shaft loads, life hours, and ambient envelope
Service life is rated at 30000 h at 100 rpm and 30 °C, and the lubricant is sealed for life — there is no relube port on this unit, so the life number is the maintenance horizon (cite:,). Maximum radial force Fr on the output shaft is 4200 N over the 30000 h life at mid-shaft and rises to 6000 N if the design point is only 10000 h; maximum axial force Fa follows the same pattern at 6000 N / 8000 N, so the loading case has to be matched to the duty, not just to the headline torque (cite:,). Operating ambient runs -25…90 °C, and the unit can be mounted in any position, which simplifies retrofitting into a packaged skid where the gearbox orientation is dictated by the upstream servo or right-angle drive (cite:,). The shaft seal is rated IP54 at the output — splash and dust, not pressure washdown — so outdoor or wet-end placement needs a cover or the unit moves inside the cabinet (cite:).
What 94 % efficiency and 70 dB buy you
Efficiency is 94 %, which is the gearing loss budget — at 800 N.m continuous that converts directly to heat that has to leave the housing, and the black anodized aluminium case is the path it leaves by (cite:,). Noise level is 70 dB at 1 m no-load, which is the bench figure — under load with a real coupling and brake, the acoustic profile will track the motor more than the gearbox, but it confirms this is a quiet planetary stage rather than a helical-bevel unit (cite:,).
Active production, sourced to RFQ
Schneider Electric GBX series gearboxes are specified against the driven machine, not the catalog — quote against the BOM with the reduction ratio, frame size, continuous torque, and shaft-load case attached, and pricing / lead time come back with the RFQ; we source through independent distribution rather than factory-direct, so confirm everything at quote time (cite:,).
