Lifecycle reality — obsolete, sourced through independent channels
Schneider Electric lists the GBX0600251401F as Obsolete. For a BOM that needs this exact 25:1 planetary gearbox, quantities are confirmed at RFQ — availability and pricing vary by lot, and no stock-holding claim is made here.
Key ratings — what they mean for fit
This is a 60 mm-diameter planetary gearbox with a 25:1 reduction ratio. The continuous output torque is 40 N.m at 100 rpm, and the maximum output torque reaches 64 N.m — the continuous figure governs normal duty, while the max handles short overloads. Efficiency is listed at 94 %, which is typical for a single-stage planetary and means about 6 % of input power is lost as heat inside the housing. Torsional backlash is 20 arc.min maximum — this is a standard-precision grade, not a zero-backlash servo gearbox. For positioning applications that need tighter repeatability, a backlash spec below 10 arc.min would be required. The housing is black anodized aluminium, the shaft is C45 steel, and the unit is lubricated for life — no maintenance oil changes needed over its rated service life of 30,000 hours at 100 rpm and 30 °C.
Mounting and environmental limits
Shaft output sealing is rated IP54, which means the output shaft end is protected against dust ingress and splashing water — suitable for most indoor industrial environments but not washdown or submersion. The axial force limit is 450 N at 100 rpm for the full 30,000-hour life, or 600 N for a 10,000-hour life. Radial force on the output shaft is 340 N for 30,000 hours, 500 N for 10,000 hours.
