Planetary gearbox — 60 mm frame, 25:1 reduction, 40 N.m continuous
The GBX0600250703F is a 60 mm-diameter planetary gearbox from Schneider Electric's GBX series, with a 25:1 reduction ratio and straight-tooth gearing. It delivers 40 N.m continuous output torque at 100 rpm and 30 °C, with a maximum intermittent torque of 64 N.m under the same conditions. Rated service life is 30,000 hours at 100 rpm and 30 °C — a realistic duty baseline for sizing in continuous-motion applications like conveyor drives or indexing tables. The housing is black anodized aluminium (60 mm OD), with a C45 steel output shaft. Shaft output sealing is rated IP54, suitable for dry indoor environments where splash or dust ingress is minimal.
Torque, backlash, and load ratings — what governs the fit
Continuous torque is 40 N.m at 100 rpm; maximum intermittent torque reaches 64 N.m at the same speed. The 20 arc-min maximum torsional backlash is typical for a straight-tooth planetary stage — acceptable for general positioning but not for precision servo axes where sub-arc-min repeatability is required. Maximum radial force (Fr) is 340 N at mid-shaft for the 30,000-hour life target, or 500 N for a 10,000-hour duty. Maximum axial force (Fa) is 450 N for the longer life, 600 N for the shorter. Both figures are at 100 rpm and 30 °C — derate for higher speed or temperature. Efficiency is listed at 94 %, which is realistic for a single-stage planetary with straight teeth. The gearbox is lubricated for life, so no maintenance oil changes are needed. Noise level is 58 dB at 1 m, no-load — quiet enough for most production-floor environments without additional acoustic enclosures.
Lifecycle status — obsolete, sourced through independent channels
Schneider Electric has marked the GBX0600250703F as obsolete. Availability is through independent surplus and broker channels. Quantities are lot-specific and confirmed at RFQ time. For a validation or change-control context, note that no direct drop-in replacement is documented. A re-evaluation of the driven load and mounting envelope will be needed if substituting into an existing design.
