The 94 % efficiency rating means 6 % of input power is lost as heat through the gear mesh — a figure that holds at the rated load and speed, so thermal rise in the enclosure stays predictable for a compact 40 mm package. Maximum torsional backlash is 24 arcmin, which sets the positioning repeatability floor for the downstream mechanism. For a 3:1 stage this is a standard commercial-grade figure — not a precision-zero-backlash unit, but adequate for indexing and conveyor drives where cumulative error is absorbed by the load. ## Load ratings and service life at 30 °C Rated service life is 30,000 hours at 100 rpm and 86 °F (30 °C) ambient. The gearbox is lubricated for life, so no field re-greasing interval — the sealed charge must last the full duty window. Maximum axial force Fa is 200 N at 100 rpm for a 10,000-hour target; radial force Fr is 200 N at mid-shaft for the same period, derating to 160 N for the full 30,000-hour life. Operating ambient temperature spans -13 to 194 °F (-25 to 90 °C). The black anodized aluminium housing dissipates heat to still air; in a confined panel or near a heat source, the upper end of the range may be reached earlier than the gear mesh itself can tolerate — the lubricant viscosity and seal life are the limiting factors above 70 °C. ## Obsolete — sourced through independent channels Schneider Electric lists the GBX0400031002F as obsolete. Sourcing runs through independent surplus and broker inventory — quantities are lot-specific and confirmed at RFQ time. The shaft material is C 45 steel, the housing is black anodized aluminium, and the torsional rigidity is 1 N·m/arcmin — these mechanical interface dimensions must be matched by any replacement candidate.","metaTitle":"Schneider Electric GBX0400031002F Planetary Gearbox, 3:1","metaDescription":"Schneider Electric GBX0400031002F planetary gearbox, 40 mm diameter, 3:1 reduction, 94% efficiency, 24 arcmin backlash.
