60:1 planetary gearbox — 44 N.m continuous, 70 N.m peak
The GBX0600600701F is a 60 mm diameter planetary gearbox from Schneider Electric with a 60:1 reduction ratio. It delivers 44 N.m continuous output torque at 100 rpm and can handle 70 N.m peak for short-duration loads. Efficiency is 94 % at rated load, typical for a planetary stage of this size. The straight-tooth design keeps cost down but generates more noise than helical — expect 58 dB at 1 m under no-load conditions.
Sourcing reality — obsolete, sourced to order
For a drop-in replacement, the mounting envelope (60 mm diameter, shaft dimensions from the C 45 shaft material) and the 60:1 ratio must match — confirm the mating half before committing.
Load limits and service life
Rated service life is 30,000 hours at 100 rpm and 30 °C ambient. The gearbox is lubricated for life — no maintenance greasing needed. Maximum axial force on the output shaft is 450 N for that 30,000-hour life; maximum radial force is 340 N applied at mid-shaft. Torsional rigidity is 2.5 N.m/arcmin, and maximum torsional backlash is 22 arc.min — the angular play under reverse load. For precision positioning applications, that backlash figure may be a limiting factor; for simple speed reduction it is usually acceptable.
Environmental and mounting
The 60 mm external diameter and straight-tooth planetary design make it a compact fit for servo or stepper motor mounting in a clean, dry cabinet or machine frame. The C 45 shaft material is standard for moderate-duty industrial gearboxes.
