Obsolete – sourced to order
Schneider Electric lists the GBX0800250704F as obsolete. We source it to order against an RFQ – availability and pricing confirmed at quote time, no runaround.
This is a planetary gearbox with straight teeth, 80 mm housing diameter, and a 25:1 reduction. The continuous output torque is 110 N.m at 100 rpm and 30 °C – that’s the figure you size for steady-state loads like conveyors or rotary indexing tables. Maximum torque peaks at 176 N.m for short-duration overloads, so you’ve got about 60 % headroom above continuous before the gear teeth see stress beyond the design envelope. Efficiency is listed at 94 % – typical for a single-stage planetary with straight teeth. That means about 6 % of input power turns into heat inside the housing. The shaft output seal is rated IP54, so it’s splash-proof but not washdown-safe; keep it out of direct hose spray in food or wet environments.
Service life and mounting constraints
Rated service life is 30,000 hours at 100 rpm and 30 °C – that’s about 3.4 years of continuous running. The gearbox is lubricated for life, so no oil-change intervals on the PM schedule. 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 target. Radial force at mid-span is 950 N (10,000 h) or 650 N (30,000 h). If your application imposes higher overhung loads – like a belt drive or chain sprocket – you’ll need to budget a service-life reduction or step up to a larger frame size.
