The GBX0600090554F is a straight-tooth planetary gearbox in a 60 mm diameter black anodized aluminium housing, with a 9:1 reduction ratio. It delivers 44 N.m continuous output torque at 100 rpm and 30 °C, and can handle 70 N.m peak at the same speed. The 94 % efficiency means about 6 % of input power is lost as heat through the gear mesh — typical for a single-stage planetary with straight teeth. Rated service life is 30,000 hours at 100 rpm and 30 °C ambient. That's about 3.4 years of continuous running at rated load. The gearbox is lubricated for life, so there's no oil-change interval to schedule — the grease fill is sealed for the service life. The 20 arc-min maximum torsional backlash is the total angular play between input and output when the direction reverses. For a positioning axis, this sets the repeatability floor — a servo system with a 1000-line encoder sees about 0.33° of lost motion at the output, which matters for index tables or pick-and-place arms but is acceptable for conveyor drives or simple speed reduction.
Sourcing reality — obsolete, sourced to order
Available through independent surplus and broker channels. Quantities are lot-specific — each unit's provenance (pulled working from a decommissioned line, new-old-stock, or customer return) is confirmed at RFQ. The 30,000-hour service life rating means a used unit with documented runtime still has predictable remaining life if the load and speed match the original duty. No pin-compatible direct replacement exists within the current Schneider planetary gearbox range. A functional replacement would require a different frame size or mounting interface — expect a mechanical redesign of the bracket and coupling.
Load limits and overhung capacity
The output shaft is C45 steel. Maximum radial force at mid-shaft is 340 N for the full 30,000-hour life, or 500 N if you accept a 10,000-hour service life. Maximum axial force is 450 N for 30,000 hours, 600 N for 10,000 hours. These are the bearing limits — a belt drive or pinion pushing harder than that will shorten life faster than the torque rating suggests. The housing itself is sealed, but the shaft lip seal is the wet-end boundary. The 30,000-hour life rating is at 30 °C — running at 90 °C ambient will reduce grease life and accelerate seal wear, though the gearbox will still turn. The torsional rigidity is 2.5 N.m/arcmin, which means the housing twists about 0.4 arc-min per N.m of applied torque — negligible for most applications but worth knowing for high-stiffness servo axes.
