Obsolete — sourcing through independent channels
Schneider Electric has marked the GBX0800320551F as obsolete. No official successor is listed. For a BOM line that still calls out this order code, availability is confirmed at RFQ through independent distribution — quantities are lot-specific and quoted per request.
Planetary gearbox — 32:1 reduction, 120 N·m continuous
This is a straight-tooth planetary gearbox with a 32:1 reduction ratio. The 80 mm-diameter housing in black anodized aluminium mates with a C45 steel output shaft. Continuous output torque is 120 N·m at 100 rpm and 30 °C; maximum output torque reaches 192 N·m under the same conditions.
Torque, backlash, and service life — what the ratings mean
Rated for 30,000 hours of service at 100 rpm and 30 °C, with a torsional rigidity of 6.5 N·m/arcmin and maximum torsional backlash of 14 arcmin. The axial force limit is 1200 N for a 10,000-hour life or 900 N for the full 30,000-hour rating. Radial force at mid-span on the output shaft is 950 N for 10,000 hours or 650 N for 30,000 hours. These derating curves matter when the gearbox drives a load with overhung or thrust components — exceeding the force limits reduces service life below the 30,000-hour baseline.
Efficiency, noise, and environmental sealing
Efficiency is listed at 94 %, which means about 6 % of input power is lost as heat through the gear mesh and bearings. Noise level at 1 m under no-load is 60 dB — roughly the level of a quiet office, acceptable for most production-floor environments. The shaft output carries an IP54 degree of protection, meaning it resists dust ingress and splashing water but is not rated for washdown or submersion.
