Lifecycle status — obsolete, sourced through independent channels
For procurement purposes, the GBX1600051001F is available through independent surplus and broker channels.
Torque ratings and service life — what the numbers mean for fit
The continuous output torque is 450 N.m at 100 rpm and 30 °C ambient, with a maximum intermittent torque of 720 N.m under the same conditions. The 5:1 reduction ratio means the input speed is five times the output speed, and the input torque is one-fifth of the output torque, minus efficiency losses. Service life is rated at 30,000 hours at 100 rpm and 30 °C. The gearbox is lubricated for life, so no field maintenance of the lubricant is required over that interval under rated load. The 94 % efficiency figure is the mechanical efficiency at rated load — the remaining 6 % is lost as heat in the gear mesh and bearings. For a 450 N.m output, the thermal dissipation is approximately 28 W, which the black anodized aluminium housing handles without forced cooling at the rated ambient.
Mechanical interface and environmental limits
The gearbox has a 160 mm outer diameter housing in black anodized aluminium. The shaft material is C45 carbon steel. Maximum axial force on the output shaft is 6000 N at 100 rpm for the full 30,000-hour service life, or 8000 N for a reduced 10,000-hour life. Maximum radial force applied at mid-distance from the output shaft is 4200 N for 30,000 hours or 6000 N for 10,000 hours. These limits govern the overhung load capacity when coupling to a belt drive or pinion. Torsional rigidity is 38 N.m/arcmin, and maximum torsional backlash is 6 arc.min. The straight-tooth design means the gearbox has higher backlash than a helical or planetary-ground alternative, which matters for positioning accuracy in indexing or servo applications. The noise level at 1 m under no-load is 70 dB, which is typical for a straight-tooth planetary stage of this size.
