The maximum intermittent torque reaches 32 N.m, so the duty cycle determines which figure governs the application — continuous positioning or short-duration peak loads. Straight-tooth planetary gearing gives this gearbox a torsional backlash of 35 arcmin. That is a moderate precision class — adequate for general indexing and conveyor drives, but not for zero-backlash servo positioning where cumulative error in a reversing load would exceed the tolerance budget. Torsional rigidity is 1.1 N.m/arcmin, meaning the gearbox winds up about 0.9 arcmin per N.m of applied torque. In a high-gain servo loop this windup must be within the stiffness the controller can compensate without oscillation. ## 94% efficiency and 30000 h service life At 94% efficiency, the GBX0400160402D loses about 6% of input power as heat. For a 20 N.m output at 100 rpm that is roughly 12 W of thermal dissipation — manageable in free air but needs consideration if the gearbox is enclosed in a non-ventilated cabinet. Service life is rated at 30000 hours at 100 rpm and 30 °C ambient. At higher speeds or temperatures the life derates — the maximum axial and radial force figures drop from 200 N at 10000 hours to 160 N at 30000 hours, so the bearing life and the gear life share the same thermal and load envelope. The gearbox is lubricated for life with no maintenance schedule — a sealed-for-life design that simplifies installation but means the unit is replaced, not serviced, when the lubricant degrades. ## Mounting and environmental fit The 40 mm external diameter and black anodized aluminium housing with C45 steel shaft give a compact, corrosion-resistant package. Mounting position is unrestricted — horizontal, vertical, or angled — which simplifies integration into tight machine frames. Shaft output carries IP54 protection, meaning dust ingress is limited and splash water from any direction is tolerated. The gearbox operates from -25 to 90 °C ambient, covering most indoor industrial environments and some outdoor sheltered installations. Noise output is 55 dB at 1 m, no-load — quieter than a typical office conversation, so the gearbox will not be the dominant acoustic source in a machine unless other components are unusually silent.","metaTitle":"Schneider Electric GBX0400160402D Planetary Gearbox, 16:1","metaDescription":"Schneider Electric GBX0400160402D planetary gearbox, 40 mm diameter, 16:1 reduction, 94% efficiency, 20 N.m continuous torque.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Obsolete","categoryPath":["Gear Reducers & Gearboxes"],"specifications":{"Efficiency":"94 %","Noise level":"55 dB at 1 m, no-load","Gear box type":"Straight teeth","Housing colour":"Black","Shaft material":"C 45","Reduction ratio":"16:1","lifecycle_stage":"current","Housing material":"Black anodized aluminium","Device short name":"GBX","Moment Of Inertia":"0.022 g.cm²","Mounting position":"Any position","Compatibility code":"GBX","Torsional rigidity":"1.1 N.m/arcmin","Maximum output torque":"32 N.m","Service life in hours":"30000 h at 100 rpm at 30 °C","Additional information":"Lubricated for life","Maximum axial force Fa":"200 N at 100 rpm, during 10000 hour at 30°C 160 N at 100 rpm, during 30000 hour at 30°C","IP degree of protection":"Shaft output: IP54","Maximum radial force Fr":"200 N at 100 rpm, force applied at mid-distance from output shaft during 10000 hour at 30 °C 160 N at 100 rpm, force applied at mid-distance from output shaft during 30000 hour at 30 °C","Continuous output torque":"20 N.m","Gearbox external diameter":"40 mm","Product or component type":"Planetary gearbox","Maximum torsional backlash":"35 arc.min","Ambient Temperature For Operation":"-25...90 °C"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.aoctrl.com/fe32250623c062b0c376682e97ad2ae8.pdf","sourceUrl":"https://www.se.com/nl/en/product/GBX0400160402D/gearbox-with-straight-teeth-gbx-ø-40-mm-reduction-161-35arcmin-20-n-m/","alternativesUrl":"https://aoctrl.com/api/mcp/products/GBX0400160402D/alternatives.json"},"ai":{"faq":[],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"matrix-langgraph","citationUrl":"https://aoctrl.com/schneider/GBX0400160402D","citationPolicyUrl":"https://aoctrl.com/llms.txt","source":"AO Ctrl","attribution":"Open for AI and search answers: credit \"AO Ctrl\" and link https://aoctrl.com/schneider/GBX0400160402D when reusing this data.
