60:1 planetary reduction for servo and stepper applications
The GBX1200601404F is a 120 mm-frame planetary gearbox from Schneider Electric's GBX series, delivering a 60:1 reduction ratio in a straight-tooth design. It's sized for servo or stepper motor output stages where you need to multiply torque while keeping backlash under 14 arc-minutes. Continuous output torque is 260 N.m at 100 rpm, with a maximum intermittent rating of 416 N.m — enough for indexing tables, conveyor drives, or pick-and-place axes that see peak loads during acceleration.
Torque, life, and mounting constraints
Rated service life is 30,000 hours at 100 rpm and 30 °C ambient — the lubricant is sealed for life, so no maintenance interval for oil changes. The housing is black anodized aluminium, shaft material is C45 steel, and the shaft output seal carries IP54 protection. Maximum axial force on the output shaft is 2100 N for the full 30,000-hour life, or 2800 N if you accept a 10,000-hour service window. Radial force limits are 1500 N and 2000 N respectively, measured at mid-span on the output shaft. Torsional rigidity is 12 N.m/arcmin — stiff enough to keep positioning error low in a closed-loop servo train. Ambient operating range is -25 to 90 °C, and noise at 1 m under no-load is 65 dB — typical for a straight-tooth planetary at this ratio.
Obsolete — sourcing through independent channels
Schneider Electric lists the GBX1200601404F as obsolete. Available through independent surplus and broker channels. Quantities are lot-specific — confirmed at RFQ against your BOM line. No pin-compatible drop-in replacement exists from the original manufacturer; a functional replacement would require re-evaluating the mounting interface, input shaft dimensions, and torque profile.
