Obsolete — sourcing through independent channels
Schneider Electric has marked the GBX0800160552F as obsolete. This planetary gearbox is available through independent surplus and broker channels. Quantities are lot-specific and confirmed at RFQ — no stock-holding claim is made here.
Torque ratings and service life at 100 rpm
Continuous output torque is 120 N.m (1062.09 lbf.in) at 100 rpm and 30 °C. Maximum output torque reaches 192 N.m (1699.3 lbf.in) under the same conditions — the margin above continuous allows for intermittent peak loads during acceleration or momentary overloads. Rated service life is 30,000 hours at 100 rpm and 30 °C. The gearbox is lubricated for life, so no maintenance interval for oil changes applies — the sealed lubrication matches the service life envelope. Maximum axial force (Fa) is 1200 N for a 10,000-hour life at 100 rpm and 30 °C, derating to 900 N for the full 30,000-hour target. Radial force (Fr) applied at mid-distance on the output shaft is 950 N for 10,000 hours or 650 N for 30,000 hours — these limits govern overhung load capacity on the output shaft.
Backlash, efficiency, and environmental limits
Maximum torsional backlash is 14 arc.min — this is the angular play between input and output when reversing direction. For positioning applications requiring tighter repeatability, a lower-backlash gearbox would be needed; 14 arc.min suits indexing and conveyor drives where reversal accuracy is not critical. Efficiency is listed at 94 %, which is typical for a single-stage planetary with straight teeth at this ratio. The 6 % loss is primarily gear mesh friction and bearing drag — expect slightly lower efficiency at higher input speeds or under partial load. The IP54 rating on the shaft output means the gearbox is protected against dust ingress and splashing water — suitable for indoor industrial environments but not washdown or outdoor exposure without additional sealing. Noise level is 60 dB at 1 m, no-load — this is the acoustic emission from the straight-tooth mesh under no-load conditions. Under load the noise will increase; 60 dB is moderate, comparable to a small conveyor drive at idle.
Construction and integration notes
The gearbox housing is black anodized aluminium, 80 mm external diameter. Shaft material is C45 carbon steel. The straight-tooth planetary design is simpler and more cost-effective than helical, but generates more noise and vibration — factor this into the mounting structure if the gearbox is coupled to a precision axis. Torsional rigidity is 6.5 N.m/arcmin — this stiffness value determines how much angular deflection occurs under load. For a 120 N.m continuous torque, the expected wind-up is roughly 18.5 arcmin (120 / 6.5), which adds to the static backlash and must be accounted for in servo tuning if used in a closed-loop system.
