The GBX1600320552F: The continuous output torque is 800 N.m at 100 rpm and 30 °C — this is the thermal limit the gearbox can sustain indefinitely without overheating, not a peak transient. Maximum output torque reaches 1280 N.m under the same conditions, but that figure is the mechanical overload ceiling; the service life rating of 30000 hours at 100 rpm applies at the continuous torque, not the maximum.
Backlash, rigidity, and load capacity — fit for positioning
Maximum torsional backlash is 10 arc.min — this is the angular play at the output shaft under reversing load, a key parameter for indexing or positioning axes where repeatability matters. Torsional rigidity is 41 N.m/arcmin, meaning the shaft wind-up under load is predictable and stays within the stiffness budget for the driven mechanism. Maximum axial force Fa is 6000 N at 100 rpm for the 30000-hour service life, and 8000 N for a 10000-hour duty cycle; radial force Fr at mid-span is 4200 N for the longer life and 6000 N for the shorter — these are the bearing limits, not the shaft bending limits.
Sourcing an obsolete planetary gearbox
Available through independent surplus and broker channels; quantities are lot-specific and confirmed at RFQ. No pin-compatible direct replacement exists from Schneider — a functional equivalent would need to match the 160 mm diameter, 32:1 ratio, 800 N.m continuous torque, and 10 arc.min backlash.
Mechanical integration — what fits the mounting envelope
Gearbox external diameter is 160 mm, housing is black anodized aluminium, and the shaft material is C45 steel — the output shaft IP54 rating means it resists dust ingress and splashing water but is not submersible. Straight teeth gearing — no helical angle, so axial thrust loads are minimal, but the noise level is higher than a helical equivalent: 70 dB at 1 m, no-load. Lubricated for life — no maintenance oil changes, but the 30000-hour service life at rated torque and speed is the replacement interval.
