60:1 planetary gearbox for precision motion control
The GBX0600601402F is a 60 mm diameter planetary gearbox from Schneider Electric's GBX series, delivering a 60:1 reduction ratio with straight-cut teeth. Continuous output torque is 44 N.m (389.4 lbf.in) at 100 rpm, with a maximum intermittent torque of 70 N.m (619.6 lbf.in) at the same speed — the margin covers acceleration peaks in indexing or positioning applications. Rated service life is 30,000 hours at 100 rpm and 30 °C ambient, with the gearbox lubricated for life — no scheduled oil changes in that window.
Efficiency, backlash, and noise — what the numbers mean for your axis
94 % efficiency means 6 % of input power is lost as heat — for a servo motor delivering 500 W, that's 30 W of thermal load the gearbox housing must shed. The black anodised aluminium housing (60 mm OD) dissipates this without forced cooling in most panel-mount layouts. Maximum torsional backlash of 22 arcmin is standard for a straight-tooth planetary at this price point — acceptable for conveyor indexing or pick-and-place where the load settles against a hard stop, but not for a CNC rotary axis that needs <5 arcmin. Noise level of 58 dB at 1 m, no-load, is quieter than a typical office printer — the straight-tooth mesh generates some whine under load, but the aluminium housing damps structure-borne vibration better than cast iron.
Obsolete — how to source this exact ratio today
Schneider Electric has classified the GBX0600601402F as obsolete. No direct successor order code is listed in the official records — the GBX series has been replaced by newer planetary families with different mounting dimensions. For BOM lines that require this exact 60:1 ratio and 60 mm frame size, independent distribution channels carry remaining new-old-stock units. If a retrofit is acceptable, the closest functional match would be a current-production planetary gearbox with 60:1 ratio, 60 mm frame, and 44 N.m continuous torque — but the shaft keyway, input pilot diameter, and bolt pattern must be verified against the existing motor flange.
The 60 mm housing diameter and 2.4 in (60 mm) external diameter fit standard NEMA 23 and 34 motor frames with the correct input pilot adapter — the gearbox input side accepts a motor shaft extension, typically clamped via the supplied keyway or collet. Shaft output IP54 means the output seal resists dust and splashing water — suitable for dry indoor conveyor lines or light washdown zones, but not for hose-down food processing or outdoor exposure. Maximum radial force (Fr) is 340 N at mid-shaft for 30,000 hour life, or 500 N for 10,000 hour life — belt-drive loads must be checked against this limit; a direct coupling is preferred to avoid overhung loads.
