Torque and duty — continuous vs peak
The GBX0800160702D: Rated 120 N.m continuous output torque, with a maximum of 192 N.m for short-duration peaks — the gap between those figures defines the overload margin for acceleration or intermittent stall. The 16:1 reduction ratio means the input motor sees roughly 1/16th of the output torque, so a servo or stepper sized for the reflected load stays within its thermal limit.
Stiffness and backlash — positioning accuracy
Torsional rigidity of 6.5 N.m/arcmin keeps windup low under load — for a 120 N.m step, the angular deflection is about 18 arcmin, which matters for contouring accuracy in a servo axis. Maximum backlash is 17 arcmin — acceptable for general indexing or conveyor positioning, but a precision application (e.g., a rotary table with encoder feedback) would need a low-backlash or zero-backlash gearbox.
Life and load derating at 30 °C
Service life is 30000 hours at 100 rpm output speed and 30 °C ambient — the axial force limit at that life is 900 N, and the radial force limit is 650 N applied at mid-distance on the output shaft. If the duty cycle pushes output torque above 120 N.m continuous or the ambient exceeds 30 °C, the bearing and gear life derates — the 10000-hour ratings (1200 N axial, 950 N radial) give a higher load ceiling for shorter-life applications.
Build and integration
80 mm outer diameter, straight teeth, black anodized aluminium housing — the IP54 rating on the shaft output means it handles dust and splashing water at the seal, but the gearbox body itself is not sealed; mount it where washdown is not directed at the housing. Lubricated for life — no maintenance port or grease interval to schedule. Mountable in any position, which simplifies layout in tight machine frames. Moment of inertia is 0.5 g.cm² reflected to the input — low enough for fast acceleration in pick-and-place or indexing axes without oversizing the motor.
