Planetary gearbox with 25:1 reduction and 40 N.m continuous torque
The Schneider Electric GBX0600250402D is a planetary gearbox with straight teeth, 60 mm external diameter, and a 25:1 reduction ratio. It delivers 40 N.m continuous output torque and up to 70 N.m maximum, making it a fit for servo-driven indexing, conveyor positioning, or any motion axis where compact planetary gearing is specified. Efficiency is rated at 94 %, and torsional rigidity is 2.5 N.m/arcmin — the gearbox holds position under load with predictable stiffness. Backlash is 25 arc.min maximum, which is standard for commercial planetary gearboxes in this class.
Load ratings and service life at speed
Service life is 30,000 hours at 100 rpm and 30 °C ambient. At that speed, maximum axial force on the output shaft is 450 N and maximum radial force (applied at mid-distance) is 340 N. For shorter duty cycles (10,000 hours), axial force can go to 600 N and radial to 500 N. The gearbox is lubricated for life and can be mounted in any position. Shaft output is IP54 — protected against dust ingress and splashing water, suitable for most factory-floor environments. Noise level is 58 dB at 1 m, no-load — quiet enough for a machine tending cell or packaging line without additional acoustic enclosure.
Obsolete — sourced through independent channels
Schneider Electric lists this gearbox as obsolete. The part is available through independent surplus and broker channels — quantities are lot-specific and confirmed at RFQ. For a BOM freeze or replacement search, the key specs to match are the 60 mm diameter, 25:1 ratio, 40 N.m continuous torque, and the 25 arc.min backlash class. Any substitute must also fit the same shaft interface and mounting pattern.
