Torque envelope and duty cycle
The GBX1600250552F delivers 700 N.m continuous output torque at 100 rpm and 30 °C, with a maximum of 1120 N.m under the same conditions — the margin above continuous is the overload headroom for acceleration or momentary peak loads, not sustained operation. Service life is rated 30,000 hours at 100 rpm and 30 °C; running at higher speed or temperature reduces that figure, so the duty cycle profile matters when sizing for a 24/7 conveyor or indexing table.
Load ratings and mechanical limits
Maximum axial force Fa is 6000 N at 100 rpm for the full 30,000-hour life, or 8000 N if you accept a 10,000-hour service interval — the trade-off lets you push harder on the output shaft when the application demands it, but the bearing life shortens accordingly. Maximum radial force Fr is 4200 N at 100 rpm for 30,000 hours, applied at mid-distance from the output shaft; increasing to 6000 N drops the life to 10,000 hours. The radial load point matters — force applied closer to the gearbox face reduces the bending moment on the shaft. Torsional rigidity is 41 N.m/arcmin, meaning the output shaft twists 1 arcminute per 41 N.m of applied torque — this stiffness figure governs positioning accuracy under load in servo-driven indexing or pick-and-place axes.
Precision and environmental fit
Maximum torsional backlash is 10 arcmin — this is the lost motion between input and output when reversing direction, critical for bidirectional positioning where each reversal eats into the tolerance budget. Shaft output sealing is IP54, meaning the output shaft end is protected against dust ingress and splashing water — suitable for dry indoor environments but not washdown or outdoor exposure without additional shaft seals.
Sourcing reality — obsolete, quoted to order
Available through independent surplus and broker channels; quantities are lot-specific and confirmed at RFQ. No pin-compatible or direct drop-in replacement is documented by Schneider, so a functional replacement would require re-evaluating the mounting interface, shaft dimensions, and torque envelope against the application. The gearbox is lubricated for life — no maintenance oil changes required, which simplifies MRO planning but means the unit is sealed and cannot be re-greased in the field.
