The GBX1200601401F is a straight-tooth planetary gearbox from Schneider Electric's GBX series, with a 120 mm housing diameter and a 60:1 reduction ratio. The planetary layout delivers higher torque density than a parallel-shaft reducer in the same envelope — the 260 N.m continuous output torque at 100 rpm and 416 N.m peak cover sustained conveyor or indexing loads with startup headroom. Efficiency is listed at 94 %, which means about 6 % of input power is lost as heat inside the gearbox. For a 3 kW motor at full load, that is roughly 180 W of thermal dissipation — enough to need free air around the black anodized aluminium housing in a confined panel or enclosure. Maximum torsional backlash is 14 arc-min. In a reversing or positioning axis, that 14 arc-min of angular play at the output shaft translates to about 0.24 mm of linear error on a 100 mm lever arm — acceptable for general material handling but too loose for precision indexing without a downstream encoder.
Sourcing reality — obsolete, no direct successor
Schneider Electric lists the GBX1200601401F as obsolete. Sourcing runs through independent surplus and broker channels — quantities are lot-specific, and availability is confirmed at RFQ time against the BOM line. The 30,000-hour service life at 100 rpm and 30 °C is the design lifetime under rated load. If the gearbox is already in service, the remaining life depends on actual duty cycle and ambient temperature — the -25 to 90 °C operating range is wide, but sustained high temperature accelerates lubricant breakdown despite the 'lubricated for life' fill.
Mounting and load ratings — what fits and what doesn't
The 120 mm external diameter and C 45 steel output shaft define the mounting interface. Maximum radial force Fr is 1500 N at 100 rpm for the 30,000-hour life target, applied at mid-distance from the output shaft. Maximum axial force Fa is 2100 N under the same conditions. Exceed these and the bearing life drops below the design window. Shaft output IP54 means the gearbox body is dust-protected and splash-resistant, but the shaft seal is the wet-end barrier — not rated for washdown or hose-down environments. The noise level is 65 dB at 1 m no-load, which is audible but below the 85 dB threshold where hearing protection is typically required in industrial settings.
