20:1 planetary reduction — torque and backlash constraints
The GBX1200201404F is a planetary gearbox with straight teeth, 120 mm housing diameter, and a 20:1 reduction ratio. Continuous output torque is 260 N.m at 100 rpm and 30 °C; maximum output torque reaches 416 N.m under the same conditions. Maximum torsional backlash is 12 arc.min — this matters for positioning accuracy in indexing or pick-and-place applications where cumulative angular error at the output shaft must stay within a known window. Torsional rigidity is 13 N.m/arcmin, meaning the shaft twists 1 arcmin for every 13 N.m of applied torque. That stiffness limits windup under load and keeps the output position predictable in reversing drives.
Sourcing reality — obsolete, quoted to order
Schneider Electric lists the GBX1200201404F as obsolete. Available through independent surplus and broker channels. No pin-compatible or direct drop-in replacement from Schneider is documented. Service life is rated 30,000 hours at 100 rpm and 30 °C. The gearbox is lubricated for life — no maintenance re-greasing interval to schedule.
Mechanical interface and environmental limits
Shaft output IP54 — the seal at the output shaft keeps out dust and splash, but the gearbox is not rated for washdown or submerged service. Ambient operating range is -25 to 90 °C. Maximum axial force Fa is 2100 N at 100 rpm for the 30,000-hour life target, or 2800 N for a 10,000-hour duty cycle. Maximum radial force Fr is 1500 N (30,000 h) or 2000 N (10,000 h), force applied at mid-distance from the output shaft. Housing is black anodized aluminium; shaft material is C45 steel. Noise level is 65 dB at 1 m, no-load — typical for a straight-tooth planetary of this size.
