Obsolete — what that means for your BOM
Schneider Electric lists the GBX1600080553F as obsolete. For a BOM that calls out this exact planetary gearbox, the procurement path is a quoted-to-order RFQ through surplus or broker stock. Quantities are lot-specific and confirmed at quote time.
8:1 reduction, 450 N.m continuous — the torque story
This is a planetary gearbox with straight teeth, 160 mm outer diameter, delivering an 8:1 reduction ratio. Continuous output torque is 450 N.m at 100 rpm and 30 °C ambient; maximum intermittent torque hits 720 N.m under the same conditions. The 94 % efficiency figure means about 6 % of input power is lost as heat through the gear mesh — consistent with a single-stage planetary set. Torsional rigidity is 38 N.m/arcmin, which keeps windup low under load for positioning applications.
Backlash, loads, and service life — the fit details
Maximum torsional backlash is 6 arc.min — this is a standard-precision planetary, not a zero-backlash unit, so it suits indexing or conveying where a few arc-minutes of lost motion is acceptable. Rated service life is 30,000 hours at 100 rpm and 30 °C. Maximum axial force on the output shaft is 6000 N for the full 30,000-hour life, or 8000 N if you accept a shorter 10,000-hour life. Maximum radial force follows the same pattern: 4200 N for 30,000 hours, 6000 N for 10,000 hours, with the force applied at mid-distance from the output shaft. The shaft is C45 steel, the housing is black anodized aluminium. Shaft output seal is rated IP54 — splash-resistant, not submersible. Ambient operating range is -25 °C to 90 °C, and it's lubricated for life, so no maintenance oil changes.
Noise and integration notes
Noise level is 70 dB at 1 m, no-load — about the hum of a quiet conversation. In a panel or machine frame, mounting isolation helps keep structure-borne noise from amplifying. At 160 mm diameter, this gearbox mates with NEMA or IEC motor flanges of matching frame size. Confirm the input shaft bore and keyway dimensions from the motor datasheet before committing the coupling.
