It delivers 260 N.m continuous output torque at 100 rpm and 30 °C, with a maximum peak of 416 N.m under the same conditions. This is a lubricated-for-life unit rated for 30,000 hours service at rated load — no oil changes, which keeps maintenance simple on a conveyor or indexing table. ## Torque, backlash, and load limits — the numbers that matter Continuous torque is 260 N.m, with a maximum intermittent peak of 416 N.m. Torsional rigidity is 13 N.m/arcmin, and maximum torsional backlash is 12 arc.min — typical for a precision planetary stage, not a high-precision zero-backlash unit. Maximum axial force (Fa) on the output shaft is 2100 N at 100 rpm for the full 30,000-hour life, or 2800 N for a 10,000-hour duty. Radial force (Fr) is 1500 N for 30,000 hours, 2000 N for 10,000 hours, measured at mid-span on the shaft. Efficiency is listed at 94 %, and noise output at 65 dB at 1 m, no-load — quiet enough for a small shop floor but not silent. ## Obsolete — sourcing through independent channels Schneider Electric lists this gearbox as obsolete. Available through independent surplus and broker channels. Quantities are lot-specific, and availability is confirmed at the time of RFQ. No pin-compatible direct replacement exists from the original manufacturer — a functional equivalent would require checking mounting dimensions, ratio, and torque class. ## Mounting and environment The gearbox has a 120 mm external diameter, black anodized aluminium housing, and C45 steel output shaft. Shaft output seal is rated IP54 — splash-resistant but not washdown-rated. The unit is lubricated for life, so no maintenance access ports are needed.","metaTitle":"Schneider Electric GBX1200121403F Planetary Gearbox, 12:1","metaDescription":"Schneider Electric GBX1200121403F planetary gearbox, 12:1 ratio, 260 N.m continuous torque, 94% efficiency.
