Continuous output torque is 450 N.m, with a maximum permissible peak of 720 N.m — the peak figure is the rating the design must respect for shock-load events (start-up, E-stop reversal, jam clearance), not the steady-state working point. ## Shaft loading and 30,000-hour service life Shaft loading is anchored to a 30,000-hour operating life at 100 rpm and 30 °C ambient: 4200 N radial (Fr) and 6000 N axial (Fa) at mid-distance from the output shaft. Short-life ratings (10,000 hours at 100 rpm and 30 °C) raise those limits to 6000 N Fr and 8000 N Fa — useful when a heavier chain or pulley arrangement shortens the design horizon. The gearbox is lubricated for life, so the service interval disappears from the maintenance plan — but the ambient envelope of -25...90 °C still bounds the installation, and any mounting position is accepted. ## Precision, efficiency and acoustic floor Torsional backlash is held under 6 arc.min and torsional rigidity is 38 N.m/arcmin — backlash is the figure that governs positioning repeatability on a servo axis, and a sub-6 arc.min reading keeps the lost-motion budget usable for most packaging and conveyor registrations. Moment of inertia is 4.63 g.cm² at the input, and efficiency is 96 %, meaning roughly 4 % of the throughput power is converted to heat — for sizing the drive's continuous current, the gearbox heat-rise must still be checked against the installation ambient. Acoustic floor is 70 dB at 1 m, no-load. ## Materials, sealing and the mechanical envelope The housing is black anodized aluminium with a C 45 shaft — the standard combination for a servo-class planetary unit — and the shaft output seals to IP54. IP54 is a splash-and-dust rating, not washdown duty; if the gearbox sits near food-and-bev or outdoor exposure, the seal needs verifying against the application environment.","metaTitle":"Schneider GBX1600081082D planetary gearbox, 8:1, 450 N.m","metaDescription":"Schneider GBX1600081082D planetary gearbox, 160 mm, 8:1 ratio, 450 N.m continuous torque, 96 % efficiency.
