5:1 planetary reduction in a 60 mm package
The GBX0600050704F is a 60 mm diameter planetary gearbox from Schneider Electric's GBX series, offering a 5:1 reduction ratio with straight-cut teeth. It delivers 40 N.m continuous output torque at 100 rpm and 30 °C, with a maximum intermittent torque of 64 N.m under the same conditions. Rated service life is 30,000 hours at 100 rpm and 30 °C, with the gearbox lubricated for life — no maintenance oil changes in the field.
Torque, backlash, and load limits that govern the fit
Continuous torque is 40 N.m; the maximum intermittent torque reaches 64 N.m — the difference matters when the application includes acceleration peaks or momentary overloads. Torsional backlash is 16 arc.min maximum, which is standard for a commercial planetary stage without anti-backlash preloading. Maximum axial force on the output shaft is 450 N for the full 30,000-hour life, or 600 N if the application accepts a reduced 10,000-hour service interval. Radial force limits are 340 N (30,000 h) and 500 N (10,000 h), measured at mid-span on the output shaft. Torsional rigidity is 2.3 N.m/arcmin — this stiffness figure tells you how much windup to expect under load. For a positioning axis, the 16 arcmin backlash plus the windup under torque sets the total lost motion the servo loop must overcome.
Efficiency, noise, and environmental ratings
Efficiency is listed at 94 %, which is typical for a single-stage planetary with straight teeth. The noise level is 58 dB at 1 m, no-load — quiet enough for a laboratory or light assembly line but not silent; the straight-cut gear geometry generates more whine than helical. The housing is black anodized aluminium, the shaft is C45 steel. Shaft output seal is rated IP54 — protected against dust ingress and splashing water, but not washdown duty.
Obsolete — sourcing through independent channels
Schneider Electric lists the GBX0600050704F as obsolete. No official successor or direct pin-compatible replacement is recorded from the manufacturer. Available through independent surplus and broker channels. The gearbox is sourced to order — no stock-holding claim is made.
