Is the GBX1600051384D still in current production?
The GBX1600051384D is a planetary gearbox in the Schneider Electric GBX family, 160 mm frame, straight-tooth construction with a 5:1 reduction and a 6 arc.min maximum torsional backlash — sized for servo applications where repeatability matters more than raw reduction ratio.
What torque and precision does the 720 N.m rating actually buy?
Maximum output torque is 720 N.m, with continuous output torque of 450 N.m — the 720 N.m figure is the peak the gearbox can deliver during acceleration or shock loading, while 450 N.m is the steady thermal limit and the one a sizing calculation should respect. Torsional rigidity is 38 N.m/arcmin and maximum torsional backlash is 6 arc.min, which puts the unit in the mid-precision planetary class — adequate for servo positioning but not low-backlash gearing for CNC contouring or printing registration. Efficiency is 96%, so a 720 N.m mechanical output draws roughly 750 N.m of input torque at the motor shaft — small enough that heat rejection is rarely a constraint, but worth knowing when sizing a smaller drive than the gearbox would imply.
How much radial and axial load can the output shaft take?
Maximum radial force Fr is 4200 N at 100 rpm applied at mid-distance from the output shaft across the full 30000 hour service life at 30 °C; the rating rises to 6000 N when the design life is shortened to 10000 hours at the same speed and temperature. Maximum axial force Fa is 6000 N at 100 rpm across 30000 hours and 8000 N at 100 rpm across 10000 hours at 30 °C — both ratings are temperature-and-life-dependent, so a higher-force application at elevated ambient temperature derates faster than the headline number suggests. The C 45 shaft output is IP54 at the seal, so splash and dust are excluded but the gearbox should not see direct washdown or submerged service; shaft sealing is the wet-end barrier, not the housing itself.
Where does a GBX 160 mm gearbox typically get bolted in?
Mounting position is any orientation, so the unit can be fitted to a vertical servo axis, an overhead gantry, or a tilted machine bed without re-derating — the gear set is lubricated for life, meaning no relube interval is on the maintenance schedule. Ambient operating temperature is -25...90 °C, so the unit tolerates an unheated cabinet in winter and a hot enclosure near a hydraulic power unit; above 30 °C the load ratings drop per the 10000/30000 hour life table quoted in the catalogue. Noise level is 70 dB at 1 m no-load, so even before a drive command the gearbox contributes a steady hum; specifying it near an operator station should factor acoustic enclosure or distance, not just vibration isolation.
