Active production, sized for the robot cell it lands in
The GBX1600251382D is a current-production planetary gearbox from Schneider Electric, built on the GBX 160 mm frame with a 25:1 reduction ratio, and it is the kind of reduction that closes the cycle budget on a servo-driven cell when the motor's stall torque and the joint's reflected inertia have to match cleanly at one fixed ratio. Continuous output torque sits at 700 N.m with a 1120 N.m peak, so the gearbox can ride through the accel/decel peaks of a palletizing or pick-and-place cycle without slipping into a short-life overload margin.
Stiffness, backlash, and what 10 arc.min means on the joint
Maximum torsional backlash is rated at 10 arc.min and torsional rigidity at 41 N.m/arcmin, a pairing that keeps the angular wind-up under load predictable — the rigidity figure matters more than the backlash number when the cell is running a high-gain position loop through the reducer. Moment of inertia at the input is 5.81 g.cm², which feeds directly into the servo drive's load-ratio calculation; at a 25:1 reduction the reflected inertia is divided by 625, so even a sizeable driven load reflects as a manageable input inertia to the motor.
Load envelope — axial and radial limits that gate the application
Maximum axial force is 6000 N at 100 rpm over the 30000-hour service life, rising to 8000 N if the design budget is shortened to 10000 hours — that time-load trade-off is the one to watch when the reducer sits on a linear actuator or any shaft that carries a sustained thrust load. Maximum radial force is 4200 N at mid-distance from the output shaft over 30000 hours, or 6000 N at 10000 hours; the location of the load matters because Fr is stated at mid-distance, so an overhung pulley or pinion sitting further out from the shaft face has to be re-rated down.
Thermal envelope, sealing, and where it actually runs
Ambient operating range is -25...90 °C and the service life is rated at 30000 hours at 100 rpm and 30 °C, with the unit lubricated for life so no scheduled oil changes enter the maintenance plan. Shaft output sealing is IP54 and the housing is black anodized aluminium, so it sits comfortably inside a control cabinet or an IP-rated machine envelope rather than in an open washdown zone — confirm the cabinet rating before specifying it onto a wet-side conveyor. Efficiency is 94 % and noise level is 70 dB at 1 m no-load, both conservative figures for a planetary stage of this size; at full load the noise figure rises with input speed, so acoustic-sensitive cells should re-check with the motor profile applied.
Mounting and drop-in fit
Mounting position is rated for any orientation, the shaft is C 45 steel, and the gearbox carries the GBX compatibility code — same-frame mating across the GBX 160 family uses the standard pilot and bolt pattern, so a different ratio on the same axis drops in without a bracket redesign.
Sourcing posture
Lifecycle status is current and the part ships under the active GBX line, so quotes run against the BOM with lead time and lot pricing confirmed at RFQ; no last-time-buy window applies to this code.
