Torque ratings and duty cycle
The GBX1200040703F: The continuous output torque is 155 N.m at 100 rpm and 30 °C, with a maximum output torque of 248 N.m under the same conditions — the continuous figure governs the steady-state load, while the maximum covers transient overloads during acceleration or jams. Service life is rated at 30,000 hours at 100 rpm and 30 °C, with the gearbox lubricated for life and sealed per IP54 at the shaft output — no maintenance re-lubrication interval to schedule.
Mechanical interface and load limits
The 120 mm diameter housing is black anodized aluminium; the output shaft is C45 steel. Maximum axial force Fa is 2100 N at 100 rpm for the 30,000-hour life target, and 2800 N for a 10,000-hour duty. Maximum radial force Fr is 1500 N at mid-span on the output shaft for the longer life, and 2000 N for the shorter. Torsional rigidity is 12 N.m/arcmin, and maximum torsional backlash is 8 arc.min — the stiffness figure tells you how much wind-up occurs under load, while the backlash spec sets the position repeatability floor for reversing or indexing applications.
Lifecycle status — obsolete
Schneider Electric lists the GBX1200040703F as obsolete. Sourcing is through independent distribution channels; quantities and pricing are confirmed at RFQ against the BOM line.
