Planetary gearbox, 160 mm, 32:1 reduction
The GBX1600320703F is a straight-tooth planetary gearbox from Schneider Electric's GBX series, with a 160 mm outer diameter and a 32:1 reduction ratio. It delivers a continuous output torque of 800 N.m (7080.6 lbf.in) at 100 rpm and 30 °C ambient. Rated efficiency is 94 %, with a noise level of 70 dB measured at 1 m under no-load conditions — relevant for noise-sensitive installations.
Torque, backlash, and service life
Maximum output torque reaches 1280 N.m (11328.9 lbf.in) at 100 rpm, with a maximum torsional backlash of 10 arc.min — this defines the positioning repeatability for indexing or precision-drive applications. Service life is rated at 30,000 hours at 100 rpm and 30 °C; the gearbox is lubricated for life, eliminating maintenance intervals for oil changes. Axial force (Fa) capacity is 6000 N at 100 rpm over 30,000 hours, and radial force (Fr) capacity is 4200 N applied at mid-shaft over the same duty cycle. Higher loads are permissible for shorter durations — 8000 N axial and 6000 N radial over 10,000 hours.
Environmental and integration ratings
The housing is black anodized aluminium with shaft output protection rated IP54 — suitable for indoor industrial environments with dust and splash exposure. Shaft material is C45 carbon steel; the 160 mm diameter housing integrates into standard mounting flanges or custom brackets for servo-motor or direct-drive interfaces.
Lifecycle and sourcing
Available through independent surplus channels; quantities are lot-specific and confirmed at RFQ. The 94 % efficiency and 800 N.m continuous torque rating should be verified against the application's duty cycle before committing to a replacement.
