100:1 planetary gearbox — 120 N.m continuous, 16 arcmin backlash
The GBX0801001402F is a straight-tooth planetary gearbox from Schneider Electric's GBX series, with an 80 mm housing diameter and a 100:1 reduction ratio. It delivers 120 N.m continuous output torque at 100 rpm, with a maximum intermittent torque of 192 N.m under the same conditions.
Load ratings and service life — what 30 000 hours means for a critical spare
Service life is rated at 30 000 hours at 100 rpm and 30 °C ambient. That is roughly 3.4 years of continuous run time — enough for a machine that runs one shift, five days a week, for over a decade. If you are stocking this as a spare for a legacy line, the 30 000-hour figure tells you the installed unit is likely near or past its design life if it has been running 24/7. The maximum radial force (Fr) is 650 N at mid-shaft, and the maximum axial force (Fa) is 900 N — both at 100 rpm and 30 °C for the full 30 000-hour service life. If the application runs at higher speed or temperature, those limits derate. The shaft output seal carries an IP54 rating, so it handles dust and splash but not washdown. Torsional rigidity is 6.3 N.m/arcmin, and the maximum backlash is 16 arcmin. That is a standard-precision grade — fine for positioning conveyors or indexing tables, but not for a servo-driven rotary axis that needs single-arcminute repeatability.
Obsolete — sourcing the GBX0801001402F as a legacy spare
Schneider Electric has marked the GBX0801001402F as obsolete. If this gearbox is on a machine that is still running, the only way to keep a spare in the cabinet is through independent surplus channels. The GBX series shares a common 80 mm frame diameter and mounting pattern, so a different ratio within the same series might physically fit — but the 100:1 reduction is specific, and no pin-compatible drop-in is confirmed.
Noise and thermal envelope — 60 dB at 1 m, -25 to 90 °C
Noise level is 60 dB at 1 m under no-load — roughly the hum of a quiet office printer. Under load the noise rises, but the straight-tooth design is inherently noisier than helical; if the application is in a sound-sensitive area, budget for an enclosure or accept the audible whine. Ambient operating temperature spans -25 to 90 °C, which covers most indoor industrial environments. The lubricant is factory-filled for life, so there is no viscosity adjustment needed across that range.
