Obsolete — sourcing through independent channels
Schneider Electric lists the GBX0800320703F as obsolete. This gearbox is sourced through independent distribution channels — quantities are confirmed at RFQ, not held as shelf stock.
32:1 planetary reduction, 120 N.m continuous
This is a planetary gearbox with straight-cut teeth, 80 mm housing diameter, and a 32:1 reduction ratio. The continuous output torque is 120 N.m at 100 rpm and 30 °C — that's the rating that governs real-world duty cycles, not the maximum peak figure. Maximum output torque reaches 192 N.m under the same conditions, but continuous operation should stay at or below the 120 N.m line for the rated 30,000-hour service life.
94% efficiency, 60 dB noise, IP54 shaft seal
Efficiency is 94 % — the 6 % loss shows up as heat in the gearbox housing, so factor that into the thermal budget of the driven system. Noise level is 60 dB at 1 m, no-load, which is quiet enough for most indoor automation lines but may need attention in open-plan assembly areas. The shaft output carries an IP54 rating — splash-resistant but not washdown-rated; keep it out of direct hose spray. Housing is black anodized aluminium, shaft is C45 steel.
Force limits and backlash for application fit
Maximum axial force (Fa) is 1200 N at 100 rpm for 10,000 hours, derating to 900 N for the full 30,000-hour life. Maximum radial force (Fr) is 950 N at 100 rpm for 10,000 hours, dropping to 650 N for 30,000 hours — both measured at mid-span on the output shaft. Torsional backlash is 14 arcmin maximum, which is standard precision for a straight-tooth planetary — adequate for indexing and positioning but not for zero-backlash servo applications. The gearbox is lubricated for life, so no maintenance oil changes are needed.
