Planetary gearbox for precision motion — 15:1 reduction, 110 N.m continuous
The GBX0800151404F is a Schneider Electric planetary gearbox with straight teeth, 80 mm external diameter, and a 15:1 reduction ratio. It delivers 110 N.m continuous output torque at 100 rpm and 30 °C, with a maximum of 176 N.m under the same conditions. Efficiency sits at 94 %, which means about 6 % of input power is lost as heat through the gear mesh — typical for a single-stage planetary set. Noise measures 60 dB at 1 m under no-load, roughly the level of a quiet office conversation. Backlash is specified at a maximum 14 arc.min — this is the angular play between input and output when reversing direction. For positioning applications that need tighter than 0.23° repeatability, a lower-backlash gearbox would be needed.
Duty ratings and mechanical limits
Service life is rated 30,000 hours at 100 rpm and 30 °C. The gearbox is lubricated for life, so no oil changes or regreasing intervals to schedule — fit it and forget it until the service hour target. Maximum axial force (Fa) on the output shaft is 1200 N for a 10,000-hour life, dropping to 900 N if you need the full 30,000 hours. Radial force (Fr) at mid-span on the output shaft is 950 N for 10,000 hours or 650 N for 30,000 hours — both at 100 rpm and 30 °C. Torsional rigidity is 6.5 N.m/arcmin — this tells you how much the gearbox twists under load. At the continuous torque of 110 N.m, expect about 17 arcmin of wind-up before the output moves.
Sourcing reality — obsolete, quoted to order
Schneider Electric lists the GBX0800151404F as obsolete. Available through independent distribution channels — quantities are sourced per RFQ and confirmed at quote time. No stock-holding claim; the spread and ship-time depend on the lot found. The housing is black anodized aluminium, shaft material is C45 steel. Single unit per package.
