The GBX1200091001F is a straight-tooth planetary gearbox from the Schneider GBX series, 120 mm housing diameter, designed to multiply servo or stepper motor torque while reducing output speed by a fixed 9:1 ratio. Continuous output torque is 210 N.m at 100 rpm and 30 °C ambient; maximum intermittent torque reaches 336 N.m under the same conditions — the margin between continuous and peak defines the overload headroom for acceleration or momentary load spikes.
Lifecycle status — obsolete, sourced through independent channels
Available through independent surplus and broker channels; quantities are lot-specific and confirmed at RFQ.
Mechanical ratings that govern the fit on a driven load
Maximum torsional backlash is 12 arc-minutes — this is the lost motion under reversing loads and governs positioning accuracy in index or pick-and-place axes. Rated service life is 30,000 hours at 100 rpm and 30 °C; the unit is lubricated for life, so no field regreasing interval is required. Maximum radial force on the output shaft is 1500 N (mid-span) for the 30,000-hour life target, rising to 2000 N for a 10,000-hour duty cycle. Axial load capacity is 2100 N for the longer life target, 2800 N for the shorter.
Efficiency and noise — practical limits on a production line
Rated efficiency is 94 %, meaning roughly 6 % of input power is lost as heat in the gear mesh and bearings — a factor in thermal management of the motor and gearbox in enclosed cabinets. Noise level is 65 dB at 1 m, no-load — a data point for acoustic qualification in noise-sensitive areas like cleanrooms or packaging lines.
Shaft output protection and material traceability
Shaft output seal is rated IP54 — suitable for dry indoor environments with dust and splash exposure, not for washdown. Housing is black anodized aluminium; shaft material is C45 carbon steel — material grades that support traceability to material certs if required for a validation package.
