This is the rating that governs sustained positioning or conveying duty — not the peak figure. Maximum output torque reaches 32 N.m (283.2 lbf.in) under the same conditions. That ceiling applies for transient overloads, not continuous operation; exceeding it risks tooth-face damage on the straight-teeth gear set. Service life is specified at 30,000 hours at 100 rpm and 30 °C. The gearbox is lubricated for life, so no field re-greasing interval is required — the oil fill is sealed for the rated lifespan. ## Mechanical constraints — backlash, shaft loads, and environment Maximum radial force Fr is 200 N at mid-shaft for 10,000-hour life, derating to 160 N for the full 30,000-hour service life. Maximum axial force Fa follows the same profile: 200 N for 10,000 hours, 160 N for 30,000 hours. Both figures are at 100 rpm and 30 °C. Shaft output is rated IP54 — protected against dust ingress and splashing water. The housing is black anodized aluminium, and the shaft material is C45 steel. Ambient operating range is -25 to 90 °C. ## Efficiency and noise — what the numbers mean for a line Efficiency is listed at 94 %. For a single-stage planetary with straight teeth, this is within the expected band — the remaining 6 % is frictional loss in the gear mesh and bearing drag. It means 20 N.m output torque draws roughly 21.3 N.m equivalent input torque from the motor. Noise level is 55 dB at 1 m, no-load. Straight-tooth gears are inherently noisier than helical; 55 dB is moderate for this class — comparable to a quiet office environment.","metaTitle":"Schneider Electric GBX0400120554F Planetary Gearbox","metaDescription":"Schneider Electric GBX0400120554F planetary gearbox, 12:1 reduction, 20 N.m continuous torque, 94% efficiency.
