What this planetary gearbox delivers
The GBX0400081403F is a 40 mm-diameter planetary gearbox with straight teeth, an 8:1 reduction ratio, and a continuous output torque of 6 N.m at 100 rpm and 30 °C. Efficiency sits at 94 % — the straight-tooth design trades a few percent for lower cost vs helical, but the loss stays within the housing's thermal budget at rated load. Noise level is 55 dB at 1 m, no-load, which is typical for a straight-tooth planetary of this size — fine for most machine-tool and conveyor drives, but if the application is in a quiet assembly area, budget for an acoustic enclosure.
Torque, life, and the limits that matter
Continuous output torque is 6 N.m; maximum output torque peaks at 10 N.m at 100 rpm and 30 °C — the extra 4 N.m is for acceleration transients, not sustained load. Service life is 30,000 hours at 100 rpm and 30 °C. If the duty cycle pushes radial or axial loads above 160 N (Fr or Fa at 100 rpm, 30 °C, 30,000 h), life drops to 10,000 h at the 200 N limit. Maximum torsional backlash is 30 arc.min — that is about 0.5° of lost motion at the output. For positioning applications requiring repeatability under 0.1°, this gearbox needs a servo with encoder feedback to close the loop after the backlash.
The housing is black anodized aluminium, 40 mm external diameter, with a C 45 steel output shaft. Shaft output IP54 means it resists dust and splash — fine for dry indoor use, but not washdown. Torsional rigidity is 1 N.m/arcmin — the shaft twist under full continuous torque is about 6 arcmin, well within the 30 arcmin backlash budget. Lubricated for life — no maintenance ports, no oil-change interval. Ambient operating range is -25 to 90 °C.
