Torque and ratio — what drives the fit
The GBX1600081003F: Continuous output torque is 450 N.m at 100 rpm, with a maximum of 720 N.m at the same speed — the continuous figure governs steady-state conveyor or rotary indexing loads; the maximum covers startup or momentary overloads. The 8:1 reduction ratio and 6 arcmin maximum torsional backlash suit precision positioning where lost motion under 0.1° is acceptable — pick-and-place or rotary tables, not zero-backlash cam drives.
Load ratings and service life
Rated for 30,000 hours at 100 rpm and 30 °C — the axial force limit is 6000 N and radial force 4200 N over that life; push to 8000 N axial or 6000 N radial and the service life drops to 10,000 hours. Shaft output IP54 means it handles dust and splash but not washdown — keep it inside a cabinet or under a cover in wet environments.
Efficiency and maintenance
94 % efficiency means 6 % of the input power becomes heat — at 450 N.m output that's about 280 W thermal load to dissipate through the black anodized aluminium housing. Lubricated for life — no oil changes, no grease ports. Noise level is 70 dB at 1 m no-load, typical for straight-tooth planetary stages.
