Planetary gearbox, 32:1 reduction, 800 N.m continuous
The GBX1600320554F is a straight-tooth planetary gearbox from Schneider Electric's GBX series, with a 160 mm housing diameter and a 32:1 reduction ratio. It delivers 800 N.m continuous output torque at 100 rpm and 30 °C ambient, with a maximum intermittent torque of 1280 N.m under the same conditions. Efficiency is listed at 94 %, which is typical for a single-stage planetary design at this ratio. The torsional rigidity of 41 N.m/arcmin and a maximum backlash of 10 arc.min make it suitable for positioning applications where repeatability matters more than absolute precision.
Load ratings and service life at 100 rpm
Rated service life is 30,000 hours at 100 rpm and 30 °C, with the gearbox lubricated for life — no maintenance oil changes. At the same speed and temperature, the maximum axial force (Fa) is 6000 N for the 30,000-hour target, or 8000 N if you accept a 10,000-hour life. Radial force (Fr) limits are 4200 N and 6000 N respectively, measured at mid-span on the output shaft. The output shaft is C45 steel, and the housing is black anodized aluminium. Shaft output protection is IP54, so it handles dust and splashing water but not washdown.
Obsolete — sourced through independent channels
Schneider Electric lists the GBX1600320554F as obsolete. No official successor or cross-reference is recorded. The gearbox is available through independent surplus and broker channels; quantities are lot-specific and confirmed at RFQ. Availability and current pricing are quoted to order.
