The GBX0600320703F is a 60 mm-diameter planetary gearbox from Schneider Electric's GBX series, with straight-cut teeth and a 32:1 reduction ratio. It delivers 44 N.m continuous output torque at 100 rpm and 30 °C ambient, with a maximum intermittent torque of 70 N.m under the same conditions. The 94 % efficiency figure means the gearbox loses only 6 % of input power to friction — relevant for sizing the upstream motor in a duty-cycle calculation. The 30,000-hour service life at rated load is a B10 life: 90 % of units will still be within spec at that point, assuming the 100 rpm output speed and 30 °C ambient are held. Torsional backlash is 20 arc.min maximum — this is a standard-precision grade, not a zero-backlash unit. If the application indexes or reverses direction under load, the lost motion at the output will show up as position error; a preloaded or low-backlash gearbox would be needed for servo-grade positioning.
Sourcing reality — obsolete, quoted to order
Schneider Electric lists this gearbox as obsolete. The part is sourced through independent surplus and broker channels — quantities are lot-specific and confirmed at RFQ. Availability and current pricing are established at quote time, not on the page. Before committing the BOM line, verify the mounting interface and input shaft dimensions against the existing assembly. The 60 mm housing diameter and IP54 shaft output seal are fixed; the C45 shaft material and black anodized aluminium housing are standard for the GBX series.
Load ratings and derating at the shaft
Maximum radial force at the output shaft is 340 N when applied at mid-span, at 100 rpm and 30 °C for the full 30,000-hour life. That drops to 500 N if you accept a 10,000-hour service life. Maximum axial force is 450 N for the 30,000-hour target, 600 N for the shorter life. These are the limits for overhung loads like pulleys or sprockets mounted directly on the shaft. The gearbox is lubricated for life — no oil-change interval. The IP54 shaft output seal keeps out dust and splashing water but is not rated for washdown; a sealed or IP65-rated gearbox would be needed for food or wet environments. Noise level is 58 dB at 1 m, no-load — this is a straight-tooth planetary, so under load the mesh noise will rise. If the application is in a quiet area (office, lab, clean room), a helical or spiral-bevel gearbox would run quieter.
