Planetary gearbox, 40:1 reduction, 40 N.m continuous — now obsolete
The GBX0600400704F is a 60 mm-diameter planetary gearbox with straight teeth, a 40:1 reduction ratio, and 40 N.m continuous output torque at 100 rpm. It delivers 94 % efficiency and holds torsional backlash to 20 arc.min maximum — a spec that matters for positioning accuracy in indexing or pick-and-place axes. Schneider Electric lists this gearbox as obsolete. No direct successor is recorded, so sourcing runs through independent surplus channels — quantities confirmed at RFQ.
Torque, life, and thermal limits for the BOM line
Continuous output torque is 40 N.m at 100 rpm and 30 °C; maximum output torque reaches 64 N.m under the same conditions. Service life is rated 30,000 hours at that duty point — lubricated for life, so no maintenance interval for grease changes. Maximum axial force on the output shaft is 450 N for the 30,000-hour life target, or 600 N for a 10,000-hour service life. Radial force limits are 340 N (30,000 h) and 500 N (10,000 h), measured at mid-span on the shaft. Torsional rigidity is 2.5 N.m/arcmin — a stiffness figure that keeps windup low under cyclic loads. Ambient operating range is -25 to 90 °C. The shaft output carries an IP54 rating — protected against dust ingress and splashing water, but not submersion. Housing is black anodised aluminium; shaft material is C45 steel.
