Planetary gearbox with 15:1 reduction
The GBX0400150701F is a planetary gearbox from Schneider Electric's GBX line, with a 15:1 reduction ratio and 40 mm external diameter. It delivers 18 N.m continuous output torque at 100 rpm and 30 °C, with a maximum intermittent torque of 29 N.m under the same conditions. Efficiency is listed at 94 %, and noise measures 55 dB at 1 m under no-load — figures that matter when the gearbox runs in a quiet lab or near operator stations.
Sourcing an obsolete gearbox
The gearbox is available through independent surplus channels; quantities are lot-specific and confirmed at RFQ. The 30,000-hour service life at rated load (100 rpm, 30 °C) means units pulled from decommissioned lines may still have useful life if the duty cycle is known.
Mounting and environmental fit
The housing is black anodized aluminium, shaft material is C45 steel, and the shaft output carries an IP54 rating — splash-resistant but not submersible, so keep it out of direct washdown zones. Operating ambient spans -25 to 90 °C. Torsional backlash is a maximum 28 arc.min — typical for a straight-tooth planetary at this price point; if your application needs under 10 arc.min for precise positioning, look at a helical or low-backlash variant. The gearbox is lubricated for life, so no maintenance schedule for oil changes.
