It delivers 120 N.m continuous output torque at 100 rpm, with a maximum of 192 N.m at the same speed. Efficiency is 94 %, and noise at no-load is 60 dB measured at 1 m — quiet enough for most indoor conveyor or positioning axes without an enclosure. The shaft output carries an IP54 rating, meaning it's protected against dust ingress and splashing water — fine for a dry machine frame, but not washdown. ## Torque, life, and the real limits Rated service life is 30,000 hours at 100 rpm and 30 °C ambient. Push the load to the maximum torque of 192 N.m and the life drops — the axial and radial force limits are also given at both 10,000 and 30,000 hour targets. At 100 rpm, maximum axial force is 1200 N for 10,000 hours, 900 N for 30,000 hours. Radial force at mid-shaft is 950 N for 10,000 hours, 650 N for 30,000 hours. Torsional backlash is 14 arc.min maximum — standard precision for a straight-tooth planetary, not a zero-backlash servo gearhead. If your axis reverses direction under load, that 14 arc.min shows up as lost motion. The housing is black anodized aluminium, shaft is C45 steel. Lubricated for life — no oil changes, but also no way to refresh the grease if the gearbox sits in a hot environment for years. ## Obsolete — what that means for sourcing Schneider Electric lists the GBX0800121403F as obsolete. The part is available through independent surplus and broker channels — quantities are lot-specific, and condition (new-in-box, pulled, or used) is confirmed at RFQ. Because it's obsolete, there is no factory lead time or authorized-distributor stock. Every lot is sourced per inquiry. The 94 % efficiency and 12:1 ratio are fixed — if your BOM calls for this exact reduction and torque, a functional replacement would need the same mounting dimensions and shaft configuration.","metaTitle":"Schneider Electric GBX0800121403F Planetary Gearbox, 12:1","metaDescription":"Schneider Electric GBX0800121403F planetary gearbox, 12:1 ratio, 120 N.m continuous torque, 94% efficiency.
