It is built around a C 45 steel shaft in a black anodized aluminium housing, lubricated for life, and it can be mounted in any position. Class fit: a planetary stage on this diameter is the right pick when the driven machine needs high torque density, low torsional backlash, and a compact in-line footprint rather than a right-angle bevel or worm arrangement. ## Torque envelope and torsional numbers a buyer actually checks Maximum output torque is 720 N·m with a continuous output torque of 450 N·m, and the maximum torsional backlash is 6 arc.min — so the part is positioned for servo-driven axes where positioning repeatability matters more than for an open-loop conveyor. Torsional rigidity is 38 N.m/arcmin, the metric that decides how much the output twists under load and how tightly the downstream controller can hold position during a transient. Efficiency is 96 %, so a 5:1 reduction that absorbs only 4 % of the mechanical power keeps the motor's continuous current draw honest on a long-duty cycle. Noise level is 70 dB at 1 m on a no-load reading — quiet enough for an operator station, but the loaded reading near the motor will read higher on the floor. ## Shaft loads and the service-life window Maximum radial force Fr is 4200 N at 100 rpm applied at mid-distance from the output shaft over 30000 hours at 30 °C, rising to 6000 N if the duty is limited to 10000 hours — the lower figure is the one that should drive the bearing-life calculation, not the higher peak. Maximum axial force Fa follows the same dual-rating logic: 6000 N over 30000 hours at 30 °C and 8000 N over 10000 hours at 30 °C, both at 100 rpm. Service life is rated 30000 hours at 100 rpm at 30 °C, with an operating ambient of -25 °C to 90 °C — wide enough for an outdoor or unconditioned cabinet, though hot-mount drives derate below the headline torque. The shaft output carries an IP54 rating, so the seal protects against splash and dust ingress at the seal lip, not against pressure wash-down — for washdown food lines a higher-rated seal stage belongs in the BOM.","metaTitle":"Schneider Electric GBX1600051385D GBX planetary gearbox, 5:1","metaDescription":"Schneider Electric GBX1600051385D planetary gearbox, 160 mm, 5:1 reduction, 720 N·m peak torque, 96 % efficiency.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Gear Reducers & Gearboxes"],"specifications":{"title":"GBX1600051385D","Efficiency":"96 %","Noise level":"70 dB at 1 m, no-load","description":"gearbox with straight teeth GBX- Ø 160 mm- reduction 5:1- < 6arcmin- 450 N.m","Gear box type":"Straight teeth","Housing colour":"Black","Shaft material":"C 45","Reduction ratio":"5:1","lifecycle_stage":"current","Housing material":"Black anodized aluminium","Device short name":"GBX","Moment Of Inertia":"6.07 g.cm²","Mounting position":"Any position","Compatibility code":"GBX","Torsional rigidity":"38 N.m/arcmin","Maximum output torque":"720 N.m","Service life in hours":"30000 h at 100 rpm at 30 °C","Additional information":"Lubricated for life","Maximum axial force Fa":"6000 N at 100 rpm, during 30000 hour at 30°C 8000 N at 100 rpm, during 10000 hour at 30°C","IP degree of protection":"Shaft output: IP54","Maximum radial force Fr":"4200 N at 100 rpm, force applied at mid-distance from output shaft during 30000 hour at 30 °C 6000 N at 100 rpm, force applied at mid-distance from output shaft during 10000 hour at 30 °C","Continuous output torque":"450 N.m","Gearbox external diameter":"160 mm","Product or component type":"Planetary gearbox","Maximum torsional backlash":"6 arc.min","Ambient Temperature For Operation":"-25...90 °C"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.aoctrl.com/73742896b87ac9d460787092dc8fc757.pdf","sourceUrl":"https://www.se.com/nl/en/product/GBX1600051385D/gearbox-with-straight-teeth-gbx-ø-160-mm-reduction-51-6arcmin-450-n-m/"},"ai":{"faq":[{"question":"What does the 96 % efficiency on GBX1600051385D mean in a real gearbox selection?","answer":"An efficiency of 96 % at a 5:1 reduction means only 4 % of the input mechanical power is lost to friction and windage inside the stage, so the motor's continuous current stays close to the ideal figure on a long-duty cycle.
