Torque and duty cycle — what the numbers mean for a motion axis
The GBX0800601401F: This planetary gearbox delivers a maximum output torque of 176 N.m at 100 rpm and 30 °C, with a continuous rating of 110 N.m under the same conditions — the continuous figure is the one to size the motor and coupling for, not the peak. The 60:1 reduction ratio means the input speed is multiplied by 60 at the output shaft — a 3000 rpm servo motor becomes 50 rpm usable at the load, with the torque multiplied inversely. Rated service life is 30,000 hours at 100 rpm and 30 °C, lubricated for life — no oil changes or regreasing intervals to schedule in the PM plan.
Backlash and stiffness — positioning repeatability
Maximum torsional backlash is 16 arc-minutes — this is the angular play between input and output when reversing direction, a key number for positioning accuracy in pick-and-place or indexing axes. Torsional rigidity is 6.3 N.m/arcmin — stiffer gearboxes wind up less under load, so the actual positioning error under torque stays closer to the backlash spec.
