Obsolete — sourcing through independent channels
Schneider Electric lists the GBX0800031402F as Obsolete. No direct replacement or successor order code is published by the manufacturer. This part is sourced through independent distribution channels — quantities are confirmed at RFQ, and availability varies by lot. No stock-holding claim is made here.
Torque ratings and duty cycle
Continuous output torque is 85 N.m (752.3 lbf.in) at 100 rpm and 30 °C — this is the working load for sustained operation. Maximum output torque reaches 136 N.m (1203.7 lbf.in) under the same conditions, covering peak loads during acceleration or momentary overloads. The 3:1 reduction ratio determines the speed/torque multiplication from motor to output shaft — a common single-stage reduction for applications needing moderate speed reduction without excessive gearbox length.
Mechanical constraints for mounting and loading
The gearbox has an 80 mm external diameter with a black anodized aluminium housing and a C45 steel output shaft. The shaft output seal is rated IP54, meaning it resists dust ingress and splashing water — suitable for indoor industrial environments but not washdown or submersion. Maximum radial force on the output shaft is 650 N at mid-shaft for a 30,000-hour life at 30 °C; axial force limit is 900 N under the same service life target. Exceeding these shortens bearing life — budget the overhung load from pulleys, sprockets, or direct-coupled loads against these figures. Torsional rigidity is 6 N.m/arcmin, and maximum torsional backlash is 9 arc.min. This backlash level is typical for standard-precision planetary gearboxes — adequate for positioning applications that do not require zero-backlash servo-grade performance.
Efficiency, noise, and service life
Rated efficiency is 94 % — typical for a single-stage planetary with straight teeth. The remaining 6 % is dissipated as heat; at 85 N.m and 100 rpm the power loss is roughly 53 W, which the aluminium housing must convect away. Noise level is 60 dB at 1 m under no-load conditions. Straight-tooth gears are inherently noisier than helical; this level is acceptable for most machine-tool and conveyor applications but may need enclosure in noise-sensitive environments. Service life is rated at 30,000 hours at 100 rpm and 30 °C. The gearbox is lubricated for life — no oil changes or regreasing intervals.
