5:1 planetary stage for servo duty cycles
The GBX0600050584D is a 60 mm planetary gearbox with a 5:1 reduction ratio, designed to match servo motor output to load speed-torque requirements in precision motion axes. Continuous output torque is 40 N.m, with a maximum intermittent rating of 64 N.m — the margin covers acceleration peaks and emergency stops without oversizing the gearbox. Torsional rigidity of 2.3 N.m/arcmin and maximum backlash of 20 arc.min define the positioning repeatability floor; for applications needing tighter angular accuracy, a lower-backlash variant in the GBX family would be the next step up.
Lifecycle reality — obsolete, sourced through surplus
Schneider Electric lists the GBX0600050584D as obsolete — no direct factory production channel remains open. The gearbox is lubricated for life and rated for 30,000 hours service at 100 rpm and 30 °C ambient, which sets the expected field life before replacement is needed. Available through independent surplus and broker channels; quantities and condition are confirmed at RFQ against the specific BOM line.
Mounting and environmental fit
The black anodized aluminium housing mounts in any position, and the shaft output carries an IP54 seal — adequate for dust and splash exposure but not for washdown or submerged service. Maximum axial force on the output shaft is 450 N at 100 rpm over the full 30,000-hour life, or 600 N for a 10,000-hour duty cycle — the shorter-life rating applies when the load exceeds the continuous-force envelope.
Efficiency and noise profile
Rated efficiency of 96 % means 4 % of input power is lost as heat in the gear mesh — this keeps the thermal rise low enough that the lubricated-for-life grease does not degrade prematurely. Noise level is 58 dB at 1 m under no-load conditions, which is quiet enough for operator-adjacent machinery without additional acoustic enclosures.
