Maximum output torque hits 312 N.m at the same speed, but that's the short-duration peak for acceleration or occasional overload — the 30000-hour service life rating applies at the continuous torque figure, not the peak. ## Backlash, stiffness, and positioning limits Maximum torsional backlash is 8 arc.min, and torsional rigidity is 12 N.m/arcmin — together these set the repeatability floor for positioning. For a pick-and-place or cam-indexing axis, that 8 arc.min at the output means the load position uncertainty is about 0.13° at the gearbox shaft before any belt or coupling compliance. Straight-tooth planetary design gives higher torque density than helical for the same diameter, but the noise floor is higher — 65 dB at 1 m no-load is the baseline; expect a few dB more under full torque. ## Sourcing this obsolete gearbox The 94 % efficiency means the thermal loss at 195 N.m and 100 rpm is about 1.3 kW — that heat has to go through the anodized aluminium housing. The IP54 shaft output seal handles incidental splash but not washdown; the housing itself is not sealed. ## Shaft loading limits for belt and pulley drives Maximum radial force Fr is 1500 N at 100 rpm for the full 30000-hour life, applied at mid-distance from the output shaft. If the application needs a shorter life — 10000 hours — that radial limit rises to 2000 N. Axial force Fa is 2100 N at the same 30000-hour condition, stepping to 2800 N for 10000 hours. The C 45 steel output shaft and lubricated-for-life grease pack mean no maintenance re-greasing schedule, but the operating temperature range of -25 to 90 °C sets the grease viscosity window — below -25 °C the starting torque climbs noticeably.","metaTitle":"Schneider Electric GBX1200050553F Planetary Gearbox","metaDescription":"Schneider Electric GBX1200050553F planetary gearbox, 5:1 reduction, 195 N.m continuous torque at 100 rpm, 94% efficiency.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Obsolete","categoryPath":["Gear Reducers & Gearboxes"],"specifications":{"Efficiency":"94 %","Noise level":"65 dB 1 m, no-load","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","Compatibility code":"GBX","Torsional rigidity":"12 N.m/arcmin","Maximum output torque":"2761.4 lbf.in (312 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":"2100 N 100 rpm, during 30000 hour at 30°C 2800 N 100 rpm, during 10000 hour at 30°C","IP Degree of Protection":"Shaft output IP54","Maximum radial force Fr":"1500 N 100 rpm, force applied at mid-distance from output shaft during 30000 hour at 30 °C 2000 N 100 rpm, force applied at mid-distance from output shaft during 10000 hour at 30 °C","Continuous output torque":"1725.9 lbf.in (195 N.m) 100 rpm 86 °F (30 °C)","Gearbox external diameter":"4.7 in (120 mm)","Product or Component Type":"Planetary gearbox","Maximum torsional backlash":"8 arc.min","Ambient Temperature For Operation":"-13...194 °F (-25...90 °C)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.aoctrl.com/9508106d479dbe8358ca101b1325386f.pdf","sourceUrl":"https://www.se.com/ca/en/product/GBX1200050553F/gearbox-with-straight-teeth-gbx-ø-120-mm-reduction-51-8arcmin-195-n-m/","alternativesUrl":"https://aoctrl.com/api/mcp/products/GBX1200050553F/alternatives.json"},"ai":{"faq":[{"question":"Where can I buy the GBX1200050553F and get a price?","answer":"Sourced to order through independent distribution against an RFQ.
