That ratio means the output shaft turns once for every 25 input revolutions — a common step for matching motor speed to a slow, high-torque load like a conveyor or rotary table. Continuous output torque is rated 110 N.m at 100 rpm and 30 °C, with a maximum intermittent torque of 176 N.m under the same conditions. The 94 % efficiency figure is the mechanical loss through the gear train at rated load — planetary designs typically hold this in the low 90s, so 94 % is a solid number for a straight-tooth stage. Service life is listed at 30,000 hours at 100 rpm and 30 °C, and the gearbox is lubricated for life — no oil changes or regreasing intervals in the field. That makes it a fit-and-forget component in a sealed drive train. ## Load limits and backlash — the mechanical envelope Maximum axial force on the output shaft is 1200 N for a 10,000-hour life, dropping to 900 N for the full 30,000-hour rating — both at 100 rpm and 30 °C. Radial force limits are 950 N (10,000 h) and 650 N (30,000 h), with the force applied at mid-span on the output shaft. These numbers govern belt-drive or overhung-load applications where the gearbox sees side loads. Torsional rigidity is 6.5 N.m/arcmin — that's the stiffness of the gear train under load. Maximum torsional backlash is 14 arcmin, which is standard for a commercial planetary stage; if your positioning loop needs tighter than that, you'd step up to a precision or low-backlash series. Shaft output protection is IP54, meaning it's dust-protected and splash-resistant but not submersible. The housing is black anodized aluminium, and the shaft material is C45 medium-carbon steel — a common combination for moderate-duty industrial gearboxes. ## Obsolete — sourcing reality and what to expect For a BOM that calls this part, the supply path is through independent surplus and broker channels. No stock-holding claim; it's a quoted-to-order line. If you're evaluating a replacement, the key mechanical envelope to match is the 80 mm housing diameter, 25:1 ratio, and 110 N.m continuous torque at the output. A functionally equivalent planetary gearbox from another series or brand would need to hit those three numbers within the same footprint.","metaTitle":"Schneider Electric GBX0800250703F Planetary Gearbox, 25:1","metaDescription":"Schneider Electric GBX0800250703F planetary gearbox, 25:1 reduction, 110 N.m continuous torque, 94% efficiency.
