Obsolete — last-time-buy sourcing for your BOM line
The Schneider Electric GBX0600081003F is officially obsolete per the manufacturer's lifecycle record. No direct successor is listed, so any remaining stock is what's left in independent distribution. This is a last-time-buy situation — if your BOM still calls this 60 mm planetary gearbox, the available quantities shrink every month. We source this part through surplus and broker channels against an RFQ.
Torque ratings — continuous vs peak, and what drives the real choice
Continuous output torque is 18 N.m at 100 rpm and 30 °C — this is the rating that governs steady-state operation. The maximum output torque reaches 29 N.m under the same conditions, but that's a peak figure for acceleration or momentary overload, not sustained duty. The 8:1 reduction ratio means the input speed is eight times the output speed, with torque multiplied by roughly the same factor minus the 94 % efficiency loss. That 6 % loss turns into heat inside the sealed housing — lubricated for life, so there's no oil-change interval, but the thermal budget is fixed. Torsional rigidity is 2.3 N.m/arcmin — this tells you how much the gear train winds up under load. For indexing or positioning applications where angular accuracy matters, that wind-up adds to the 16 arc.min maximum backlash. Combined, they set the repeatability floor.
Service life, loads, and where it fits
Rated service life is 30,000 hours at 100 rpm and 30 °C, with the output shaft sealed to IP54. That ingress rating means it's splash-resistant but not washdown-rated — keep it out of direct hose spray or steam cleaning. Maximum axial force on the output shaft is 450 N for the full 30,000-hour life, or 600 N if you accept a shorter 10,000-hour life. Radial force limits are 340 N and 500 N respectively, measured at mid-span on the shaft. These numbers govern belt-drive or overhung-load applications — exceed them and the bearing life drops fast. The 60 mm outer diameter and black anodized aluminium housing with C45 steel shaft make this a compact, corrosion-resistant package for servo or stepper motor output stages in light industrial machinery. Ambient range is -25 to 90 °C, so it's fine in unheated plant environments but not inside an oven.
Noise and vibration — what 58 dB means on the line
Noise level is 58 dB at 1 m, no-load, with straight-cut teeth. That's quieter than a typical conveyor drive but louder than a helical gearbox of the same size. If your application runs near operator stations, this spec tells you whether you need an acoustic enclosure.
