Service life is 30000 h at 100 rpm at 30 °C, which fixes the envelope for both the radial and axial load ratings published alongside it. ## Shaft loading at the gearbox output Maximum radial force Fr is 1500 N at 100 rpm over the 30000 h life (2000 N at 100 rpm over a 10000 h life), force applied at mid-distance from the output shaft — the mid-span figure is the realistic case because most couplings and pulleys do not sit flush against the gearbox face. Maximum axial force Fa is 2100 N at 100 rpm over the 30000 h life (2800 N at 100 rpm over a 10000 h life) — axial capacity drops alongside life the same way radial does, so a heavy-overhung load that drops the design life to 10000 h buys back load headroom at the cost of service hours. ## Mechanical and environmental envelope Output shaft seal is IP54 with the housing in black anodized aluminium and a C 45 shaft — IP54 keeps dust and splashed water out, which is enough for a typical cabinet-interior or sheltered-machine mounting but not for a washdown cell. Operating temperature runs -25...90 °C and the unit mounts in any position — the lubricant is sealed for life, so orientation never reaches a refill interval within the design life. Efficiency is 94 % and noise level is 65 dB at 1 m, no-load — efficiency is what the motor has to make up thermally, and the noise figure is the no-load baseline that rises slightly once the gears are under torque. ## Sourcing the obsolete line item marks the part obsolete, so the only fresh-supply path is independent distribution holding traceable stock — quoted against the BOM quantity with availability and pricing confirmed at RFQ, never an immediacy promise.","metaTitle":"Schneider GBX1200400841D Planetary Gearbox, 40:1, 230 N.m","metaDescription":"Schneider GBX1200400841D Ø 120 mm planetary gearbox, 40:1 ratio, 230 N.m continuous torque.
