The maximum output torque reaches 312 N.m for short-duration overloads, but the continuous rating is the one to size the application against. Efficiency is 94 % at rated load — the 6 % loss converts to heat that the black anodized aluminium housing must dissipate. The housing diameter is 120 mm, so the gearbox fits into a compact drivetrain envelope. ## Backlash, rigidity, and load limits — what the numbers mean for fit Maximum torsional backlash is 8 arc.min. For indexing or positioning applications where the load reverses, this backlash translates to lost motion at the output. If the application requires less than 8 arc.min repeatability, a low-backlash or precision planetary stage is needed instead. Torsional rigidity is 12 N.m/arcmin — the gearbox twists 1 arcmin for every 12 N.m of applied torque. This stiffness affects the system's natural frequency and positioning accuracy under load, especially in servo-driven axes. Maximum axial force Fa is 2100 N at 100 rpm for the 30000-hour service life, and 2800 N for a 10000-hour life. Maximum radial force Fr is 1500 N at 30000 hours, 2000 N at 10000 hours — both measured with the force applied at mid-distance from the output shaft. Exceeding these limits shortens bearing life. The service life is rated at 30000 hours at 100 rpm and 30 °C. The gearbox is lubricated for life — no re-greasing interval. ## Noise, ingress protection, and shaft material Noise level is 65 dB at 1 m, no-load. Straight-cut teeth are inherently noisier than helical, so this figure is typical for a straight-tooth planetary. If the application is in a noise-sensitive area, a helical planetary would run quieter. The shaft output seal is rated IP54 — dust-protected and splash-resistant. The housing itself is black anodized aluminium; the shaft material is C45 medium-carbon steel, hardened and ground. The shaft output IP54 means the gearbox can tolerate occasional washdown splashes but not sustained immersion.","metaTitle":"Schneider Electric GBX1200051001F planetary gearbox, 5:1","metaDescription":"Schneider Electric GBX1200051001F planetary gearbox, 5:1 reduction, 195 N.m continuous torque, 94 % efficiency.
