Obsolete — sourcing through independent channels
Schneider Electric has marked the GBX1600120552F as obsolete. No official successor is listed from the manufacturer. This unit is available through independent supply channels; quantities and pricing are confirmed at RFQ against your BOM line.
Planetary gearbox, 160 mm, 12:1 reduction
This is a straight-tooth planetary gearbox from the GBX series, 160 mm external diameter, with a 12:1 reduction ratio. It delivers 800 N.m continuous output torque at 100 rpm and 30 °C ambient, with a peak capability of 1280 N.m under the same conditions. The rated service life is 30,000 hours at 100 rpm and 30 °C — a solid baseline for continuous-duty indexing or conveyor applications where the duty cycle keeps the gearbox within its thermal envelope.
Torque, backlash, and mechanical limits
Maximum torsional backlash is 10 arcmin, which places this in the standard-precision class — adequate for positioning axes where repeatability within a few arcminutes is acceptable, but not for high-precision servo-driven rotary tables. Torsional rigidity is 41 N.m/arcmin, meaning the gearbox windup under load is predictable and linear within the elastic range. Maximum axial force (Fa) is 6000 N at 100 rpm for the full 30,000-hour life, or 8000 N for a 10,000-hour duty cycle. Maximum radial force (Fr) at mid-shaft is 4200 N for 30,000 hours, 6000 N for 10,000 hours.
Efficiency, noise, and thermal limits
Efficiency is listed at 94 % — typical for a single-stage planetary with straight teeth at this ratio. The noise level is 70 dB at 1 m under no-load conditions, which is moderate; expect a few dB higher under full load depending on the motor coupling and mounting stiffness. The gearbox is lubricated for life from the factory, so no field maintenance is required — but that also means the lubricant grade is fixed and cannot be changed for extreme-temperature applications outside this range.
Materials and construction
Housing is black anodized aluminium — lightweight and corrosion-resistant in normal industrial atmospheres. The output shaft is C45 carbon steel, which provides adequate hardness for keyed or shrink-disc connections but is not stainless; in humid or washdown environments, shaft surface protection (paint or seal) should be considered.
