The 30 arcmin maximum torsional backlash is typical for a commercial-grade precision stage — adequate for indexing and positioning where the load doesn't reverse under torque, but not for a servo axis that needs to hold position through direction changes. Efficiency is listed at 94 %, which means about 6 % of the input power is lost as heat in the gear mesh and bearing drag. For a 15 N.m rated output (the description line), that's roughly 1 N.m of thermal loss — the black anodised aluminium housing sinks that without forced cooling in most duty cycles. ## Load ratings and service life at 100 rpm Rated service life is 30,000 hours at 100 rpm and 86 °F (30 °C). At that same speed, maximum radial force (Fr) is 200 N for a 10,000-hour target, dropping to 160 N if you need the full 30,000-hour life. Axial force (Fa) follows the same derating curve — 200 N for 10,000 hours, 160 N for 30,000 hours. Both assume the radial load is applied at mid-distance from the output shaft. The torsional rigidity figure of 1 N.m/arcmin tells you how much the output shaft twists under load — 1 N.m of torque produces 1 arcmin of windup. That's a relatively soft stage; if your application needs to hold position under varying load, the backlash plus windup will show up as lost motion at the load. ## Obsolete — sourcing through independent channels Schneider Electric has marked the GBX0400040554F as obsolete. The part is available through independent surplus and broker channels — quantities are lot-specific and confirmed at RFQ. No pin-compatible or form-fit-function replacement is documented in the GBX family. The gearbox is lubricated for life and carries an IP54 rating at the shaft output — suitable for indoor environments with dust and light splash, but not washdown.","metaTitle":"Schneider Electric GBX0400040554F Planetary Gearbox","metaDescription":"Schneider Electric GBX0400040554F planetary gearbox, 4:1 reduction, 94% efficiency, 30 arcmin backlash, IP54.
