Planetary gearbox, 15:1 reduction, 230 N.m continuous — obsolete, sourced on request
The GBX1200151403F is a straight-tooth planetary gearbox from Schneider Electric's GBX series, with a 120 mm housing diameter and a 15:1 reduction ratio. It delivers 230 N.m continuous output torque at 100 rpm and 30 °C, with a maximum peak torque of 368 N.m under the same conditions. Rated efficiency is 94 %, and torsional backlash is held to 12 arcmin maximum — figures that matter when the gearbox sits between a servo motor and a positioning stage. The unit is lubricated for life and rated for 30,000 hours service at 100 rpm and 30 °C.
Load capacity and bearing limits — axial and radial force ratings
Maximum axial force (Fa) is 2100 N at 100 rpm for the 30,000-hour service life, or 2800 N for a 10,000-hour duty cycle. Maximum radial force (Fr) is 1500 N at 100 rpm for 30,000 hours, applied at mid-distance from the output shaft, or 2000 N for 10,000 hours. Torsional rigidity is 13 N.m/arcmin, which gives a sense of how much the output shaft twists under load — relevant for applications where angular accuracy matters.
Environmental sealing and operating range
Shaft output sealing is IP54, meaning the gearbox is protected against dust ingress and splashing water — suitable for factory-floor environments where washdown is not direct. The black anodized aluminium housing provides corrosion resistance and aids heat dissipation; the output shaft is C45 medium-carbon steel.
Lifecycle status — obsolete, sourced through independent channels
Schneider Electric lists the GBX1200151403F as obsolete. No official successor or direct cross-reference is recorded from the manufacturer. Available through independent surplus and broker channels; quantities and pricing confirmed at RFQ.
