The GBX0600400401D: This is a 60 mm-diameter planetary gearbox with straight teeth, reduction ratio 40:1, and a maximum output torque of 70 N.m — the continuous rating sits at 40 N.m, so the peak-to-continuous margin is about 1.75×, typical for intermittent duty cycles in positioning axes. Torsional rigidity is 2.5 N.m/arcmin and the maximum backlash is 25 arcmin — that's a standard-precision class, not a zero-backlash unit, so it fits applications where the load doesn't reverse direction under high torque or where the controller compensates for windup. Efficiency is 94 %, which is about what you expect from a single-stage planetary with straight teeth at this ratio — the losses are mostly gear mesh friction and bearing drag, not heat buildup in the housing.
Service life and loading — 30,000 hours at 100 rpm
Rated service life is 30,000 hours at 100 rpm and 30 °C ambient — that's the bearing and gear life under the continuous torque rating. At the maximum axial force of 450 N (at 100 rpm, 30,000-hour target) or 600 N (10,000-hour target), the life drops with the higher load. Maximum radial force is 340 N for the 30,000-hour target and 500 N for the 10,000-hour target, both measured at mid-distance on the output shaft — overhung loads from pulleys or pinions need to stay inside these envelopes to avoid premature bearing wear. The gearbox is lubricated for life, so no oil-change interval to schedule — the grease fill is sealed at the factory and the IP54 shaft output keeps contaminants out of the bearing cavity.
Obsolete — sourcing through independent channels
Available through independent surplus and broker channels — quantities are lot-specific and confirmed at RFQ. No pin-compatible direct replacement exists from Schneider within the same GBX family — a functional equivalent would require matching the 60 mm diameter, 40:1 ratio, 70 N.m peak torque, and the 25 arcmin backlash class, which may mean a different brand or a board-spin if the mounting interface differs.
