GBX1600151084D — what the order code covers
The Schneider Electric GBX1600151084D is a planetary gearbox in the GBX series, 160 mm frame, with straight-cut teeth and a 15:1 reduction ratio — built to sit downstream of a servo or stepper drive where a compact inline reducer with controlled backlash is needed.
Service life and ambient operating window
Service life is rated at 30000 h at 100 rpm and 30 °C ambient, with an operating temperature window of -25...90 °C — at higher speeds or temperatures the life curve shortens, so a high-cycle application near the upper temperature limit needs to be derated against the published curve. The unit is lubricated for life, so grease condition is not a maintenance interval the buyer has to plan around; field service shifts to seal, coupling, and bearing health at the input and output shafts.
Shaft loading — axial and radial limits
Maximum axial force Fa is 6000 N at 100 rpm over a 30000 h life at 30 °C, rising to 8000 N over a 10000 h life; maximum radial force Fr is 4200 N at the mid-distance from the output shaft over 30000 h, or 6000 N over 10000 h — these are the figures that drive pulley, sprocket, and pinion sizing, not the headline torque alone.
Backlash, rigidity, and inertia
Maximum torsional backlash is 10 arc.min and torsional rigidity 41 N.m/arcmin — backlash is the spec a positioning application tracks (repeatability from the servo loop's perspective), rigidity is the spec a high-acceleration load tracks (wind-up under shock). Moment of inertia at the input is 12.35 g.cm², low enough that it does not dominate the drive's acceleration budget.
Sealing, mounting, and noise
Shaft output is sealed to IP54 and the gearbox may be mounted in any position — the IP54 figure is a splash/dust rating, not washdown duty, so cabinet mounting or sheltered machine framing is the envelope. Noise floor at 1 m no-load is 70 dB, with efficiency at 94 %, so losses show up as heat at the housing rather than as acoustic load on the line.
Lifecycle and sourcing posture
No official second source or successor is on the record for this exact 15:1 GBX variant, so any functional swap is a different ratio or frame and would need a redesign pass, not a BOM drop-in.
