What this planetary gearbox delivers
The GBX0600051004F is a 60 mm-diameter planetary gearbox from Schneider Electric's GBX series, with a 5:1 reduction ratio and straight-tooth gearing. It delivers 40 N.m continuous output torque at 100 rpm and 30 °C ambient, with a peak rating of 64 N.m under the same conditions. Efficiency is listed at 94 % — the straight-tooth profile trades some efficiency against helical for lower cost and simpler backlash control. The noise level at 58 dB 1 m, no-load, is typical for a straight-tooth planetary stage of this size.
Torque, life, and force limits — the real selection numbers
Continuous torque is 40 N.m at 100 rpm; the maximum output torque of 64 N.m is the overload ceiling, not the running point. Service life is rated 30,000 hours at 100 rpm and 30 °C — the gearbox is lubricated for life, so no oil-change interval to schedule. Axial force on the output shaft is limited to 450 N for the full 30,000-hour life, or 600 N if you accept a 10,000-hour service window. Radial force, applied at mid-shaft, is 340 N for 30,000 hours or 500 N for 10,000 hours — these are the bearing-life limits, not the shaft bending limit. Maximum torsional backlash is 16 arc.min — acceptable for positioning axes where the load doesn't reverse frequently, but not for high-precision indexing. Torsional rigidity is 2.3 N.m/arcmin, which gives the stiffness under load.
Sourcing reality — obsolete, sourced to order
Schneider Electric lists the GBX0600051004F as obsolete. No official successor or cross-reference is recorded from the manufacturer. The part is available through independent surplus and broker channels — quantities are lot-specific and confirmed at RFQ. For a line-down replacement, the key envelope dimensions are the 60 mm outer diameter and the 5:1 ratio. The IP54 shaft output seal means it's splash-protected at the output end but not submersible.
