16:1 planetary with 20 N.m continuous — what the ratings mean
The GBX0400161003F is a straight-tooth planetary gearbox from Schneider Electric's GBX series, sized for a 40 mm output diameter and a 16:1 reduction ratio. Continuous output torque is 20 N.m at 100 rpm and 30 °C ambient, with a maximum intermittent torque of 32 N.m at the same conditions — the continuous figure governs the duty cycle for positioning or indexing applications. Efficiency is listed at 94 %, and noise at 55 dB measured 1 m away under no-load — useful for noise-sensitive environments like lab automation or packaging lines. The rated service life is 30,000 hours at 100 rpm and 30 °C, with the gearbox lubricated for life.
Sourcing reality — obsolete, quoted to order
Schneider Electric has marked the GBX0400161003F as obsolete. The part is available through independent surplus and broker channels — quantities are lot-specific and confirmed at RFQ. No stock-holding claim here — it's a per-order search.
Mechanical fit and environmental limits
The housing is black anodized aluminium, shaft material is C45 steel. Shaft output carries IP54 protection — splash-resistant but not washdown-rated. Ambient operating range is -25 to 90 °C, so it suits unheated machine enclosures or near-motor environments. Maximum radial force at the output shaft is 200 N (mid-shaft) for a 10,000-hour life, derated to 160 N for the full 30,000-hour service life. Maximum axial force follows the same pattern. Torsional rigidity is 1.1 N.m/arcmin — the stiffness matters for servo-driven positioning where load reversal causes lost motion.
