The GBX1600160554F is a straight-tooth planetary gearbox in the 160 mm diameter frame, delivering a 16:1 reduction ratio. The continuous output torque is 800 N.m at 100 rpm, with a peak of 1280 N.m available at the same speed — the margin covers acceleration transients and occasional overloads without oversizing the motor. Backlash is 10 arcmin maximum — this is a standard-precision class, not a zero-backlash stage. For indexing or positioning axes that reverse load direction, the 10 arcmin windup at the output means the controller must account for that lost motion in the position loop or the repeatability budget. Torsional rigidity is 41 N.m/arcmin — the gearbox resists windup under load. At the 800 N.m continuous rating, the torsional deflection is roughly 19.5 arcmin (800 ÷ 41), which adds to the static backlash. The combined lost motion at rated torque is about 29.5 arcmin — a factor when sizing for positioning accuracy.
Load ratings and service life — axial and radial limits
Service life is 30000 hours at 100 rpm and 30 °C ambient — that is about 3.4 years of continuous operation. The gearbox is lubricated for life, so no oil-change interval to schedule. Maximum axial force on the output shaft is 6000 N for the full 30000-hour life, or 8000 N if the application accepts a shorter 10000-hour life. Radial force limits are 4200 N and 6000 N respectively, measured at mid-shaft. These are the bearing limits — overhung loads or belt drives need to stay within these envelopes or the bearing race spalls early. Efficiency is 94 % — the 6 % loss is heat dissipated through the black anodized aluminium housing. At 800 N.m and 100 rpm (8.4 kW mechanical input), the heat loss is about 500 W. The housing must have free air circulation; enclosed mounting without airflow will push the -25 to 90 °C operating range toward the upper limit.
Obsolete — sourcing through independent channels
Schneider Electric lists the GBX1600160554F as obsolete. Noise level is 70 dB at 1 m, no-load — this is a straight-tooth gearbox, so the noise is higher than a helical or spiral-bevel unit of the same ratio. If the application is in a sound-sensitive area, the 70 dB baseline at no-load will rise under load. Shaft output protection is IP54 — the seal at the output shaft keeps out dust and splashing water, but it is not rated for washdown or submersion. The C45 steel shaft is standard carbon steel; in humid or corrosive environments, the shaft surface needs protection or the seal lip will wear against rust.
