Planetary gearbox, 80 mm, 4:1 — torque and life at 100 rpm
The GBX0800040554F is a straight-tooth planetary gearbox in the 80 mm diameter frame, delivering a 4:1 reduction ratio. Continuous output torque is 115 N.m at 100 rpm and 30 °C; maximum intermittent torque reaches 184 N.m under the same conditions. Rated service life is 30,000 hours at 100 rpm and 30 °C — the gearbox is lubricated for life and requires no maintenance re-greasing in the field.
Efficiency, noise, and mechanical limits
Efficiency is listed at 94 % — a solid figure for a single-stage planetary with straight teeth, meaning roughly 6 % of input power is lost to friction and windage at rated load. Noise level is 60 dB at 1 m under no-load conditions — this is quiet enough for indoor conveyor or packaging lines where operator exposure limits apply. Maximum torsional backlash is 9 arc-minutes, which defines the positioning repeatability for indexing or pick-and-place applications. Axial force on the output shaft is limited to 1200 N for a 10,000-hour life at 100 rpm, derating to 900 N for the full 30,000-hour service life. Radial force at mid-shaft is 950 N for 10,000 hours, dropping to 650 N for 30,000 hours.
Obsolete — sourcing through independent channels
Schneider Electric has marked the GBX0800040554F as obsolete. This part is available through independent surplus and broker channels.
