Planetary gearbox — 15:1 reduction, 110 N·m continuous
The GBX0800150552F is a planetary gearbox with straight teeth, 80 mm external diameter, and a 15:1 reduction ratio. It delivers a continuous output torque of 110 N·m (973.6 lbf·in) at 100 rpm and 30 °C, with a maximum output torque of 176 N·m (1557.7 lbf·in) under the same conditions. Efficiency is listed at 94 %, which means about 6 % of input power is lost to friction and windage — typical for a single-stage planetary with straight teeth. The rated service life is 30,000 hours at 100 rpm and 30 °C, with lubricant sealed for life (no maintenance refill needed).
Load ratings and mechanical limits
Maximum axial force (Fa) is 1200 N at 100 rpm for a 10,000-hour life at 30 °C, derating to 900 N for the full 30,000-hour service interval. Maximum radial force (Fr) applied at mid-distance on the output shaft is 950 N for 10,000 hours or 650 N for 30,000 hours at the same speed and temperature. Torsional rigidity is 6.5 N·m/arcmin, and maximum torsional backlash is 14 arcmin — this is the angular play at the output under no load. The shaft output seal is rated IP54, so the gearbox is splash-resistant but not suitable for washdown or submerged service. Noise level at 1 m under no-load is 60 dB — roughly the hum of a quiet office, not a high-pitched whine. The housing is black anodized aluminium; the shaft material is C45 carbon steel.
Obsolete — sourcing through independent channels
Schneider Electric lists this gearbox as obsolete. No official successor or cross-reference is recorded from the manufacturer. The part is available through independent surplus and broker channels; quantities are lot-specific and confirmed at RFQ. The 80 mm diameter, 15:1 ratio, and 110 N·m continuous torque are the key fit parameters — confirm the mating shaft dimensions and mounting interface against your existing installation before committing.
