Planetary gearbox, 60:1 reduction, 110 N.m continuous
This GBX0800601404F is a planetary gearbox with straight teeth, 80 mm outer diameter, and a 60:1 reduction ratio. The continuous output torque is 110 N.m (973.6 lbf.in) at 100 rpm and 30 °C, with a maximum output torque of 176 N.m (1557.7 lbf.in) under the same conditions — the margin above continuous gives you headroom for short-duration peak loads, but sustained operation should stay at or below the 110 N.m figure. Efficiency is 94%, which means about 6% of input power is lost as heat in the gear train. That is typical for a single-stage planetary of this precision class, and the lubricated-for-life design means no maintenance schedule for oil changes — the grease fill is sealed for the rated service life.
Lifecycle status — obsolete, sourced through surplus channels
For a line-down situation or a BOM freeze that needs this exact ratio and torque class, the part is available through independent distribution on a quoted-to-order basis.
Service life and load limits at 100 rpm
Rated service life is 30,000 hours at 100 rpm and 30 °C. If your duty cycle runs the gearbox continuously at that speed, that works out to about 3.4 years of 24/7 operation before the internal bearings and gear surfaces reach their wear limit. The maximum axial force (Fa) is 1200 N for a 10,000-hour life target, dropping to 900 N for the full 30,000-hour window. Maximum radial force (Fr) at mid-span on the output shaft is 950 N for 10,000 hours, 650 N for 30,000 hours. Torsional rigidity is 6.3 N.m/arcmin — that is the stiffness figure for the output shaft; a load of 6.3 N.m twists the shaft by one arc-minute. For positioning applications, the maximum torsional backlash is 16 arc-min, which is a moderate figure — fine for conveyor drives or indexing where the load direction is consistent, but not for precision servo positioning where you need single-arc-minute repeatability.
Environmental and mechanical fit
The output shaft carries an IP54 rating — protected against dust ingress and water splashes from any direction. That is suitable for factory-floor environments with occasional washdown or coolant mist, but not for continuous hose-down or submersion. The housing is black anodized aluminium, shaft material is C45 steel. Noise level is 60 dB at 1 m under no-load conditions. That is roughly the sound of a normal conversation — quiet enough for a machine-tool enclosure or a conveyor drive without additional acoustic cladding.
