What sits on the shaft
The part is a planetary gearbox in Schneider Electric's GBX line, identified by the order code GBX1600091384D and classed as a straight-tooth unit with a 160 mm external gearbox diameter. Reduction ratio is 9:1 with maximum torsional backlash of 10 arc.min, paired with a torsional rigidity of 41 N.m/arcmin — the figure that governs how the gearbox resists wind-up under step loads on the output shaft. Service life is rated at 30000 h at 100 rpm at 30 °C, and the gearbox is lubricated for life, so the unit ships sealed with no scheduled oil change on the maintenance schedule.
Efficiency and acoustic footprint
Efficiency is 94 %, which at a 9:1 reduction means roughly 6 % of the input power is dissipated as heat in the gear stage — sized for the thermal envelope of the housing under continuous duty at 100 rpm. Noise level is 70 dB at 1 m under no-load, measured in free-field conditions; in-panel mounting typically attenuates this further, but the figure matters when the gearbox is specified near operator stations or sound-sensitive areas.
Shaft loading envelope
Maximum radial force Fr is 4200 N at 100 rpm applied at mid-distance from the output shaft over 30000 h at 30 °C, or 6000 N over 10000 h — the higher figure only applies when the service-life target is shortened accordingly. Maximum axial force Fa is 6000 N at 100 rpm over 30000 h at 30 °C, rising to 8000 N when the life target drops to 10000 h, so any thrust load from the driven machine must be checked against the rated duty cycle. The shaft is C 45 carbon steel and the output seal carries an IP54 rating, so dust ingress and splashing water are tolerated but the gearbox is not rated for jet wash or immersion — a relevant constraint in food, beverage, or outdoor skids.
Mounting and deployment envelope
Ambient temperature for operation is -25 to 90 °C, covering typical cabinet and machine-room environments without derating the service-life figure quoted above.
Lifecycle and sourcing posture
Lifecycle stage is recorded as current, so the part remains an active line within the Schneider Electric GBX series; no successor order code is listed on the record. Pricing and availability are confirmed against an RFQ for production quantities; the storefront quotes to order through independent distribution with full traceability on the supplied units.
