Continuous output torque is 110 N.m at 100 rpm and 30 °C, with a maximum intermittent torque of 176 N.m at the same speed and temperature. This gearbox is now listed as Obsolete by Schneider Electric, so new builds looking for a drop-in replacement will need to source through surplus or broker channels. The specs here are what you need to confirm fit for a line-down replacement or a BOM freeze. ## Torque, backlash, and service life at rated speed Rated continuous torque is 110 N.m (973.6 lbf.in) at 100 rpm and 30 °C; the maximum output torque hits 176 N.m (1557.7 lbf.in) under the same conditions — that 60 % headroom covers short-duration overloads. Torsional rigidity is 6 N.m/arcmin, meaning the shaft twists 1 arcmin for every 6 N.m of applied torque, which matters for positioning accuracy in pick-and-place or indexing applications. Maximum torsional backlash is 9 arc.min — this is the lost motion when reversing direction, a key spec for servo-driven axes where repeatability matters. Service life is 30 000 hours at 100 rpm and 30 °C, and the unit is lubricated for life, so no maintenance oil changes in that window. ## Efficiency, noise, and mechanical ratings Efficiency is 94 %, which is typical for a single-stage planetary with straight teeth — the rest is heat loss, so the black anodized aluminium housing (80 mm OD) acts as the heat sink. Noise level is 60 dB at 1 m, no-load, quiet enough for a small shop floor without enclosures. Maximum axial force (Fa) is 1200 N at 100 rpm for 10 000 hours, derating to 900 N for the full 30 000-hour life. Maximum radial force (Fr) applied mid-shaft is 950 N at 100 rpm for 10 000 hours, or 650 N for 30 000 hours. Shaft output has IP54 protection — splash-resistant but not washdown-rated. Shaft material is C45 carbon steel, housing is black anodized aluminium. ## Sourcing an obsolete GBX gearbox That means the only channel is independent surplus and broker stock. We source these per RFQ — confirm the quantity and we'll check our network for traceable units. No pin-compatible drop-in from the current Schneider catalog has been published. If you're holding a BOM with this code, the decision is either to buy available surplus now or re-engineer the mount and ratio for a current planetary gearbox.","metaTitle":"Schneider GBX0800051004F planetary gearbox, 5:1","metaDescription":"Schneider Electric GBX0800051004F planetary gearbox, 5:1 ratio, 110 N.m continuous torque, 94% efficiency.
