The GBX1200160704F is a planetary gearbox with a 16:1 reduction ratio, delivering a continuous output torque of 260 N.m at 100 rpm and a maximum intermittent torque of 416 N.m under the same conditions — the ceiling before the gear teeth yield, not a sustained rating. The 94% efficiency figure means that at rated load, 6% of the input power is lost as heat through the straight-tooth mesh and bearing friction — a number that holds provided the gearbox is operated within its 30000-hour service life at 100 rpm and 30 °C ambient. Torsional rigidity is 13 N.m/arcmin, which tells you the windup per unit torque: at the continuous rating of 260 N.m, the angular deflection under load is about 20 arcminutes — relevant if the downstream encoder or servo loop expects less than a quarter-degree of compliance in the mechanical path.
Mechanical limits and mounting constraints
The shaft output carries an IP54 rating — the seal keeps out dust and splashing water, but it is not submersible; the gearbox is suited for cabinet-mounted or protected positions on a conveyor or packaging line, not washdown zones. Maximum axial force on the output shaft is 2100 N for the full 30000-hour life, climbing to 2800 N if you accept a 10000-hour service interval — the bearing selection governs this trade-off, not the housing. Radial force applied at mid-span on the output shaft is limited to 1500 N for 30000 hours, or 2000 N for 10000 hours — a sprocket or pulley overhung load must stay within these bounds or the output bearing life drops below the nameplate figure. The housing is black anodized aluminium with a 120 mm external diameter; the shaft is C45 steel. The gearbox is lubricated for life — no oil-change interval, which simplifies MRO but means the internal grease grade was selected at the factory for the full 30000-hour operating window.
