Torque and duty cycle
The GBX1200030551F: This planetary gearbox delivers a continuous output torque of 115 N.m at 100 rpm and 30 °C, with a maximum intermittent torque of 184 N.m at the same speed and temperature — the headroom covers acceleration peaks and short overloads without exceeding the 30,000-hour service life target.
Mechanical stiffness and precision
Maximum torsional backlash is 8 arc.min, and torsional rigidity is 12 N.m/arcmin — the gearbox holds position repeatability within that window under load, which matters for indexing and positioning axes where cumulative play stacks across multiple stages. Rated axial force Fa is 2100 N and radial force Fr is 1500 N at 100 rpm for the full 30,000-hour life; at 10,000-hour duty these rise to 2800 N and 2000 N respectively — the radial force is specified at mid-distance on the output shaft, so overhung loads need derating.
Lifecycle and sourcing
Available through independent surplus channels; quantities are lot-specific and confirmed at RFQ. The 94 % efficiency and 65 dB noise level at 1 m no-load are the original published figures — a used unit pulled from a running line should match these if the bearings and gear mesh are still within spec.
