Planetary gearbox, 60 mm frame, 8:1 reduction
The GBX0600081402F is a straight-tooth planetary gearbox from Schneider Electric's GBX series, sized for a 60 mm output diameter and an 8:1 reduction ratio. It delivers 18 N.m continuous output torque at 100 rpm, with a maximum intermittent torque of 29 N.m at the same speed.
Torque, backlash, and load ratings that matter
Continuous torque is 18 N.m (159.3 lbf.in) at 100 rpm and 30 °C — that's your steady-state design point for sizing the driven load. The maximum output torque of 29 N.m (256.7 lbf.in) covers starting and momentary overloads, but don't plan on running there continuously. Maximum torsional backlash is 16 arc.min — this is a standard-precision planetary, not a zero-backlash stage. If your application needs position repeatability under 10 arc.min, this box won't hold it without a preload or a higher-grade unit. Rated service life is 30,000 hours at 100 rpm and 30 °C — that's about 3.4 years of continuous running. The axial force limit is 450 N and the radial force limit is 340 N at mid-shaft, both at the same 100 rpm and 30,000-hour life target. Push to 600 N axial or 500 N radial and the life drops to 10,000 hours. Efficiency is 94 %, which is typical for a single-stage planetary with straight teeth. The noise level at no-load is 58 dB measured 1 m away — quiet enough for a small shop floor but not silent.
Build and environmental limits
Housing is black anodized aluminium, 60 mm external diameter. Shaft is C45 steel. The shaft output seal carries IP54 protection — splash-resistant but not hose-down rated, so keep it out of direct washdown zones. Operating ambient temperature spans -25 to 90 °C (-13 to 194 °F). The gearbox is lubricated for life — no maintenance ports, no oil-change schedule. Just mount it and run.
For a BOM that needs this exact gearbox, the only channel is independent surplus or new-old-stock inventory. We source it to order against an RFQ — availability and pricing confirmed at quote time, no stock-holding claim on a discontinued part.
