16:1 planetary reduction with 44 N.m continuous torque
The GBX0600161403F is a straight-tooth planetary gearbox from Schneider Electric's GBX series, sized for servo and stepper motor output stages where a 16:1 reduction ratio is needed. The 60 mm housing diameter and 44 N.m continuous output torque (70 N.m peak at 100 rpm) place it in the compact precision class — the torsional rigidity of 2.5 N.m/arcmin keeps windup under control in positioning axes. The 94% efficiency figure is the mechanical loss floor through the planetary stage at rated load; the 58 dB noise level at 1 m no-load is low enough for lab or light assembly environments. Service life is rated 30,000 hours at 100 rpm and 30°C ambient, with the gearbox lubricated for life — no maintenance interval for oil changes.
Load ratings and thermal envelope
Maximum axial force on the output shaft is 450 N at the 30,000-hour service life rating, climbing to 600 N if you accept a 10,000-hour life. Radial force follows the same pattern: 340 N at 30,000 hours, 500 N at 10,000 hours, measured at mid-span on the output shaft. These are the limits that govern bearing life — overshoot them and the 30,000-hour figure drops. The operating ambient range is -25 to 90°C, with the IP54 shaft output protection meaning the housing seals against dust ingress and splashing water at the shaft exit — not submersible, but fine for most cabinet-mounted or machine-frame installations. The black anodized aluminium housing and C45 steel shaft are standard for this torque class. Maximum torsional backlash is 20 arc.min — this is the angular play at the output under reversing load. For single-direction constant-load applications it's irrelevant; for bidirectional positioning or torque-reversal cycles, budget this into the system compliance budget.
Obsolete — sourcing through independent channels
Schneider Electric lists the GBX0600161403F as obsolete. Sourcing runs through independent distribution — quantities are confirmed at RFQ against the specific BOM line, and the gearbox is quoted to order.
