16:1 planetary gearbox — 260 N.m continuous, now obsolete
The GBX1200160701F is a straight-tooth planetary gearbox from Schneider Electric's GBX series, sized for applications needing a 16:1 reduction ratio and 260 N.m continuous output torque at 100 rpm and 30 °C ambient. The maximum output torque reaches 416 N.m under the same conditions, giving a 1.6× peak-to-continuous margin for transient overloads like acceleration or jam recovery. The 120 mm-diameter black anodized aluminium housing with C45 steel shafting is rated IP54 at the shaft output, meaning the rotating seal resists dust ingress and splashing water — suitable for washdown-adjacent positions but not submerged or high-pressure spray zones. The unit is lubricated for life, so no scheduled grease changes are needed over its 30,000-hour service life at rated load.
Load limits and bearing capacity
The gearbox is rated for 2100 N axial force (Fa) and 1500 N radial force (Fr) at 100 rpm for the full 30,000-hour life, with higher short-term limits of 2800 N axial and 2000 N radial for a 10,000-hour duty cycle. These values assume the radial force is applied at the mid-point of the output shaft — a belt drive or pinion mounted further out will reduce the allowable Fr proportionally. Torsional rigidity is 13 N.m/arcmin, and maximum torsional backlash is 12 arcmin. For positioning applications, the 12-arcmin backlash means the output shaft can rotate up to 0.2° before the load engages — acceptable for conveyor indexing or rotary table positioning, but too loose for precision servo axes without a separate encoder on the load side.
Lifecycle reality — obsolete, no direct successor
Schneider Electric has marked the GBX1200160701F as obsolete. For a BOM freeze or line-down replacement, the 120 mm housing diameter and 16:1 ratio are the binding constraints. A functional replacement from another manufacturer will need to match the mounting flange pattern, shaft dimensions, and output torque within the same envelope — expect a board or bracket spin if the new gearbox uses a different bolt circle or shaft keyway.
