Planetary gearbox, 40 mm, 5:1 reduction — obsolete, sourced on request
The GBX0400050702F is a 40 mm-diameter planetary gearbox from Schneider Electric's GBX series, with a 5:1 reduction ratio and straight-tooth gearing. It delivers a continuous output torque of 14 N.m at 100 rpm and 30 °C, with a maximum output torque of 22 N.m under the same conditions. Schneider Electric lists this gearbox as obsolete. No official successor is recorded.
Torque, backlash, and service life at rated load
The service life is 30,000 hours at 100 rpm and 30 °C, with the gearbox lubricated for life — no maintenance re-greasing interval. Maximum torsional backlash is 24 arc.min, with a torsional rigidity of 1 N.m/arcmin. For applications requiring positioning repeatability, the 24 arc.min figure means the output shaft can lag the input by up to 0.4° under reversing load — acceptable for conveyor drives or indexing tables where absolute precision is not critical. Axial force (Fa) and radial force (Fr) limits are derated with service life: at 100 rpm and 30 °C, both are 200 N for a 10,000-hour life, dropping to 160 N for the full 30,000-hour rating. Radial force is measured at the midpoint of the output shaft.
Efficiency, noise, and environmental ratings
Efficiency is listed at 94 %, meaning 6 % of input power is lost as heat in the gear mesh and bearings. Noise level is 55 dB at 1 m, no-load — quiet enough for indoor machinery without acoustic enclosures. Shaft output protection is IP54, so the output seal resists dust ingress and splashing water — suitable for washdown areas but not immersion. Housing is black anodized aluminium; shaft material is C45 carbon steel. The 40 mm external diameter and straight-tooth profile mean it fits compact mounting footprints typical of servo-motor or stepper-motor output stages.
