Torque envelope and backlash
The GBX1600161084D is sized for 800 N.m continuous output torque with a 1280 N.m peak ceiling, so it absorbs inertial transients from start/stop cycles without slipping past its rated duty window. Backlash is held to 10 arc.min maximum and torsional rigidity is 41 N.m/arcmin — tight enough that positioning axes driven through it show clean follow-through without spring-back.
Shaft loading over the rated service life
Maximum radial force is 4200 N at 100 rpm over a 30000-hour life at 30 °C, with the load assumed applied at mid-distance from the output shaft; the same shaft tolerates 6000 N axial force over the same duty window. Pushing either figure to 8000 N axial or 6000 N radial is allowed only if the duty is derated to 10000 hours — the catalogue keeps both ratings on the same row so the buyer can match the application envelope, not just one of them.
Efficiency and acoustic signature
Rated efficiency is 94 %, with a no-load noise floor of 70 dB at 1 m — the lubricated-for-life planetary train keeps the steady-state losses in line with the GBX family mean. The 7.47 g.cm² moment of inertia is the inertia the upstream motor sees reflected through 16:1; budgeting this against the motor's rotor inertia prevents the sizing tool from over-torqueing on accel ramps.
Mechanical envelope and installation
The gearbox mounts in any position, with a black anodized aluminium housing and a C 45 shaft sealing to IP54 at the output. Ambient operating range is -25 to 90 °C, so the unit sits inside an enclosure or on a machine frame without climate conditioning in most factory environments. The 160 mm external diameter is the form-factor anchor when laying out a servo or stepper axis — input coupling and output flange geometry follow from this OD across the GBX family.
Lifecycle posture and sourcing
Lifecycle status is active — the GBX1600161084D is on current production and is specified into new builds without a last-time-buy window.
