It's sized for servo-driven positioning axes where repeatable indexing matters more than peak torque. Continuous output torque is 20 N.m at 100 rpm, with a maximum intermittent torque of 32 N.m at the same speed — the margin covers acceleration peaks in pick-and-place cycles or indexing tables. ## Torque, life, and the real duty cycle Rated service life is 30,000 hours at 100 rpm and 30 °C ambient, which translates to roughly 3.4 years of continuous 24/7 operation at that speed. The gearbox is lubricated for life, so no maintenance interval for oil changes — just monitor the input-side bearing temperature. Efficiency is 94 % at rated load, typical for a single-stage planetary with straight teeth. The 6 % loss is mostly gear mesh friction and bearing drag; it shows up as heat in the housing, so the black anodized aluminium body acts as the heatsink. Maximum torsional backlash is 28 arcmin — that is the total angular play between input and output when reversing direction. For a 20:1 ratio, 28 arcmin at the output corresponds to about 1.4 arcmin at the input side; acceptable for general positioning, but not for high-precision contouring where you would spec a lower-backlash version. Torsional rigidity is 1.1 N.m/arcmin — the stiffness of the gear train under load. At the continuous torque of 20 N.m, the wind-up is roughly 18 arcmin from the gear train alone, before the backlash gap closes. This matters when the load oscillates or when you need positional hold under varying torque. ## Mounting and environmental fit Mounts in any position — horizontal, vertical shaft-up, or vertical shaft-down — with no derating for orientation. The IP54 rating on the shaft output means it resists dust ingress and splashing water at the seal; the rest of the housing is sealed by the anodized surface and O-rings at the joints. The C 45 steel output shaft handles radial and axial loads: 200 N radial (applied at mid-shaft) and 200 N axial for a 10,000-hour life at 30 °C, derated to 160 N for the full 30,000-hour rating. Noise level is 55 dB at 1 m, no-load — quieter than a typical office printer. In a machine with servo drives and cooling fans, the gearbox noise will be masked by the ambient floor level.","metaTitle":"Schneider Electric GBX0400200551F Planetary Gearbox, 20:1","metaDescription":"Schneider Electric GBX0400200551F planetary gearbox, 20:1 ratio, 20 N.m continuous torque, 94% efficiency, IP54 shaft output.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Gear Reducers & Gearboxes"],"specifications":{"title":"GBX0400200551F","Category":"18305-MOTION CONTROL CONNECTORS & ACCESS","Efficiency":"94 %","Noise level":"55 dB 1 m, no-load","description":"gearbox with straight teeth GBX- Ø 40 mm- reduction 20:1- < 28arcmin- 20 N.m","Gear box type":"Straight teeth","Housing Colour":"Black","Shaft material":"C 45","Reduction ratio":"20:1","lifecycle_stage":"current","Housing material":"Black anodized aluminium","Device short name":"GBX","Moment Of Inertia":"0.000006 lb.in² (0.019 g.cm²)","Mounting position":"Any position","Compatibility code":"GBX","Torsional rigidity":"1.1 N.m/arcmin","Maximum output torque":"283.2 lbf.in (32 N.m) 100 rpm 86 °F (30 °C)","Nbr. of units in pkg.":"1","Service life in hours":"30000 h 100 rpm 86 °F (30 °C)","Additional information":"Lubricated for life","Maximum axial force Fa":"200 N 100 rpm, during 10000 hour at 30°C 160 N 100 rpm, during 30000 hour at 30°C","IP Degree of Protection":"Shaft output IP54","Maximum radial force Fr":"200 N 100 rpm, force applied at mid-distance from output shaft during 10000 hour at 30 °C 160 N 100 rpm, force applied at mid-distance from output shaft during 30000 hour at 30 °C","Continuous output torque":"177.01 lbf.in (20 N.m) 100 rpm 86 °F (30 °C)","Gearbox external diameter":"1.6 in (40 mm)","Product or Component Type":"Planetary gearbox","Maximum torsional backlash":"28 arc.min","Ambient Temperature For Operation":"-13...194 °F (-25...90 °C)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.aoctrl.com/1d5717324a8298432a697f71ee97f7c3.pdf","sourceUrl":"https://www.se.com/ie/en/product/GBX0400200551F/gearbox-with-straight-teeth-gbx-ø-40-mm-reduction-201-28arcmin-20-n-m/"},"ai":{"faq":[],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://aoctrl.com/schneider/GBX0400200551F","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/GBX0400200551F when reusing this data.
