Obsolete — last-time-buy sourcing
The GBX0400040702F: We hold remaining stock from the final production run. This covers you for years of spares or a last build before you requalify a replacement. EOL is a buy signal here — once these are gone, the only source is the surplus channel at unknown pricing.
4:1 planetary reduction — what the ratings deliver
The GBX0400040702F is a straight-tooth planetary gearbox with a 4:1 reduction ratio. Continuous output torque is 15 N.m at 100 rpm and 30 °C; maximum intermittent torque reaches 24 N.m under the same conditions. Efficiency is 94 % — typical for a single-stage planetary of this size. The 30 arcmin torsional backlash suits positioning axes where repeatability matters more than absolute precision; for servo-grade zero-backlash applications you would step up to a preloaded or harmonic drive. Rated service life is 30,000 hours at 100 rpm and 30 °C. The gearbox is lubricated for life — no maintenance schedule for oil changes, which simplifies installation in sealed or hard-to-reach locations.
Mounting and environmental limits
The 40 mm diameter black anodized aluminium housing carries a shaft-output IP54 rating — protected against dust ingress and splashing water, but not submersion. The shaft is C45 steel, which handles the rated axial force of 200 N and radial force of 200 N at 100 rpm for the 10,000-hour duty cycle. Ambient operating temperature spans -25 °C to 90 °C. Noise level is 55 dB at 1 m under no-load — quiet enough for laboratory or light industrial environments without an acoustic enclosure.
