5:1 planetary gearbox, 40 mm frame — torque and service life at 100 rpm
The GBX0400050703F is a planetary gearbox with straight teeth, 40 mm external diameter, and a 5:1 reduction ratio. It delivers 14 N.m continuous output torque at 100 rpm and 30 °C, with a maximum intermittent torque of 22 N.m under the same conditions. Rated service life is 30,000 hours at 100 rpm and 30 °C, with the gearbox lubricated for life — no scheduled oil changes in the field.
Efficiency, noise, and environmental limits
Efficiency is listed at 94 %, which means the gearbox wastes about 6 % of the input power as heat — relevant for thermal budgeting in a sealed enclosure. Noise level is 55 dB at 1 m, no-load — comparable to a quiet office environment; the straight-tooth geometry is inherently noisier than helical but acceptable for many servo axes. Ambient temperature range spans -25 °C to 90 °C, and the shaft output carries an IP54 rating — protected against dust ingress and splashing water, but not submersion.
Mechanical load ratings — axial and radial force limits
Maximum axial force (Fa) is 200 N at 100 rpm for a 10,000-hour life, derated to 160 N for the full 30,000-hour service life. Radial force (Fr) follows the same profile: 200 N for 10,000 hours, 160 N for 30,000 hours, applied at mid-distance from the output shaft. Torsional rigidity is 1 N.m/arcmin, and maximum torsional backlash is 24 arc.min — this is a standard-precision gearbox, not a zero-backlash unit, so it suits positioning axes where some lost motion is acceptable.
Lifecycle status and sourcing
The GBX0400050703F is available through independent distribution channels.
