100:1 planetary reduction with 120 N.m continuous torque
The GBX0801001404F: This is a straight-tooth planetary gearbox, 80 mm diameter, with a 100:1 reduction ratio. Continuous output torque is 120 N.m at 100 rpm and 30 °C; maximum output torque reaches 192 N.m under the same conditions. The 94 % efficiency figure means about 6 % of input power is lost as heat through the gear train — typical for a single-stage planetary at this ratio.
Service life, backlash, and load limits
Rated service life is 30,000 hours at 100 rpm and 30 °C. Maximum torsional backlash is 16 arcmin — this is a standard-precision planetary, not a zero-backlash unit, so it suits positioning applications where some lost motion is acceptable. Maximum axial force on the output shaft is 1200 N for a 10,000-hour life, derated to 900 N for the full 30,000-hour service life. Maximum radial force applied at mid-distance on the output shaft is 950 N for 10,000 hours, derated to 650 N for 30,000 hours.
Build and environmental specs
Housing is black anodized aluminium; the output shaft is C45 steel. Shaft output seal is rated IP54 — splash-resistant but not submersible, so mount the gearbox with the shaft seal oriented away from direct washdown. The unit is lubricated for life, so no oil-change interval to schedule. Noise level is 60 dB at 1 m, no-load — quiet enough for an indoor conveyor or packaging line without an enclosure.
