Planetary gearbox, 80 mm frame, 8:1 reduction
The GBX0800081402F is a Schneider Electric planetary gearbox with straight teeth, 80 mm external diameter, and a reduction ratio of 8:1. Continuous output torque is 50 N.m at 100 rpm and 30 °C, with a maximum of 80 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 maintenance oil changes required in the field.
Torque, backlash, and load ratings
Maximum torsional backlash is 9 arc.min — this sets the positioning repeatability floor in reversing or indexing applications. Torsional rigidity is 6 N.m/arcmin, so the windup under the continuous 50 N.m load is roughly 8.3 arcmin. Maximum axial force (Fa) is 1200 N for a 10,000-hour life at 100 rpm and 30 °C, derating to 900 N for the full 30,000-hour service life. Maximum radial force (Fr) is 950 N at 10,000 hours, dropping to 650 N at 30,000 hours, with the force applied at mid-distance from the output shaft. Efficiency is 94 % — typical for a single-stage planetary with straight teeth. Noise level is 60 dB at 1 m, no-load, which is audible but within normal limits for a machine-mount gearbox in an industrial enclosure.
Sourcing — obsolete, quoted to order
Schneider Electric lists the GBX0800081402F as obsolete. No official successor or cross-reference is recorded. The gearbox carries an IP54 rating on the shaft output, operates from -25 to 90 °C, and is built with a black anodized aluminium housing and C45 steel shaft. Compliance documentation (RoHS, REACH) is available on request at quote time.
