No official successor or direct replacement is listed from the manufacturer. This gearbox is available through independent surplus and broker channels. ## Planetary gearbox — 4:1 reduction in a 120 mm package Rated for 248 N.m maximum output torque and 155 N.m continuous at 100 rpm and 30 °C ambient. The 94 % efficiency is respectable for a single-stage straight-tooth planetary — expect some thermal loss at sustained full load but the lubricated-for-life design eliminates maintenance intervals. Service life is 30,000 hours at the rated 100 rpm and 30 °C. The 8 arcmin maximum torsional backlash places it in a moderate-precision class — adequate for positioning applications that don't need zero-backlash performance. ## Load ratings and mechanical limits Maximum radial force Fr is 1500 N for the 30,000-hour life target, applied at mid-distance from the output shaft. The axial force Fa limit is 2100 N under the same duty cycle. Both figures can be increased for shorter service — 2000 N radial and 2800 N axial for a 10,000-hour life at 100 rpm. Torsional rigidity is 12 N.m/arcmin — the gearbox resists windup under load, which matters for positioning accuracy in indexing or servo-follower applications. The IP54 rating on the shaft output means it handles dust and splash but isn't rated for washdown. Operating ambient range spans -25 to 90 °C, so it works in unheated enclosures or near motor heat. Noise level at 65 dB at 1 m, no-load, is typical for a straight-tooth planetary — helical or spiral-bevel designs would run quieter, but this is a cost-optimized stage.","metaTitle":"Schneider Electric GBX1200040552F Planetary Gearbox, 4:1","metaDescription":"Schneider Electric GBX1200040552F planetary gearbox, 4:1 ratio, 155 N.m continuous torque, 94% efficiency, 8 arcmin backlash.","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":"4:1","lifecycle_stage":"current","Housing material":"Black anodized aluminium","Device short name":"GBX","Compatibility code":"GBX","Torsional rigidity":"12 N.m/arcmin","Maximum output torque":"2195.0 lbf.in (248 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":"1371.9 lbf.in (155 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/bcedd8adfe7884f0d883ce2a513913fc.pdf","sourceUrl":"https://www.se.com/nz/en/product/GBX1200040552F/gearbox-with-straight-teeth-gbx-ø-120-mm-reduction-41-8arcmin-155-n-m/","alternativesUrl":"https://aoctrl.com/api/mcp/products/GBX1200040552F/alternatives.json"},"ai":{"faq":[{"question":"What is the continuous torque rating of GBX1200040552F?","answer":"Continuous output torque is 155 N.m (1371.9 lbf.in) at 100 rpm and 30 °C.
