The GBX0600201002F is a 60 mm planetary gearbox with straight teeth and a 20:1 reduction ratio, delivering 44 N.m continuous output torque at 100 rpm and 30 °C ambient. That continuous torque figure — 389.4 lbf.in — is the load you can hold indefinitely without overheating the gear mesh; the maximum output torque of 70 N.m (619.6 lbf.in) is the ceiling for intermittent peak loads, not steady-state running. Efficiency is listed at 94 %, which means about 6 % of the input power is lost as heat in the gear train — typical for a single-stage planetary at this ratio. The noise level of 58 dB at 1 m, no-load, is quiet enough for an enclosed cabinet but audible in a silent room; under load the gear whine will rise a few dB.
Mounting and environmental constraints
The housing is black anodized aluminium with a 60 mm external diameter. The shaft output carries an IP54 rating — meaning it resists dust ingress and splashing water at the seal, but it is not submersible. Mount it with the output shaft horizontal or vertical-down; the lubricated-for-life grease charge stays in place, but a vertical-up mount can starve the upper bearing over the 30000-hour service life at rated load. Shaft material is C45 carbon steel — standard for this torque class. The maximum axial force Fa is 450 N at 100 rpm for the full 30000-hour life, or 600 N if you only need 10000 hours. Radial force Fr at mid-span on the output shaft is 340 N for 30000 hours, 500 N for 10000 hours. Exceed these and the bearing race will spall before the gear teeth wear out.
Lifecycle reality — obsolete, sourced to order
Schneider Electric lists the GBX0600201002F as obsolete. That means the only supply channel is independent surplus and broker stock — quantities are lot-specific and confirmed at RFQ. If you are planning a line-down replacement or a BOM freeze, budget for a functional alternative with a different mounting footprint; a board spin or adapter plate is likely. The torsional backlash is rated at a maximum of 20 arc.min — that is the lost motion in the gear train when reversing direction. For positioning applications that need better than 0.3° repeatability, this box will need a preloaded or low-backlash alternative. The torsional rigidity of 2.5 N.m/arcmin tells you how much wind-up you get under load: at 44 N.m continuous, expect about 17.6 arcmin of elastic deflection before the backlash is taken up.
