Planetary reduction, 16:1, 44 N.m continuous — load envelope for a precision stage
The GBX0600161003F is a straight-tooth planetary gearbox from Schneider Electric's GBX series, 60 mm housing diameter, with a 16:1 reduction ratio. Continuous output torque is 44 N.m at 100 rpm and 30 °C; maximum output torque reaches 70 N.m under the same conditions. This defines the load envelope for a precision rotary stage or indexer — the continuous figure governs the duty cycle, the maximum covers transient peaks during acceleration or reversal. Torsional rigidity is 2.5 N.m/arcmin, and maximum torsional backlash is 20 arc.min. For a positioning axis, backlash this high means the gearbox is suited to applications where reversal accuracy is not critical — conveyor drives, rotary tables with one-direction indexing, or tensioning stations — rather than a servo axis requiring under 5 arc.min.
94 % efficiency, 58 dB noise floor — energy and acoustic constraints
Rated efficiency is 94 %, and the no-load noise level is 58 dB measured at 1 m. The efficiency figure is typical for a single-stage planetary of this ratio; it means roughly 6 % of the input power is lost as heat in the gear mesh and bearings. The noise level — 58 dB at 1 m — is quiet enough for a lab or packaging line but not silent; if the application is in a cleanroom or quiet assembly area, the gearbox should be mounted on vibration-damping pads or isolated from the machine frame. Lubricated for life — no maintenance oil changes. The service life is 30,000 hours at 100 rpm and 30 °C. At higher speeds or ambient temperatures above 30 °C, the life derates; the axial and radial force limits also drop with speed. For a continuous-duty line running 8,000 hours per year, 30,000 hours is roughly 3.75 years before the gearbox is due for replacement.
Obsolete — sourcing through independent channels only
Schneider Electric lists the GBX0600161003F as obsolete. The only path to this exact part number is through independent surplus or broker channels. Availability is lot-specific and confirmed at RFQ — the buyer should treat this as a last-time-buy or legacy-replacement scenario and verify quantities against the BOM before committing the line. The lifecycle stage field shows 'current', but the product status is 'Obsolete' — a contradiction that likely reflects a data-entry lag. The practical takeaway: treat the part as end-of-life. If the application can accept a different frame size or ratio, a parametric search against the GBX family's current catalog is the next step; otherwise, the gearbox is sourced as-is through distribution.
