The GBX0800030702D is a planetary gearbox with straight teeth, 80 mm external diameter, and a 3:1 reduction ratio. It delivers 85 N.m continuous output torque and peaks at 136 N.m maximum — sized for servo or stepper motor output stages where compact, low-backlash power transmission is needed. Rated 96% efficiency means only 4% of input power is lost as heat — a meaningful advantage in thermally constrained enclosures or battery-powered systems. The 12 arc.min maximum torsional backlash is typical for a straight-tooth planetary stage; if your application requires tighter positioning repeatability (indexing or pick-and-place), a helical or precision-geared stage would be the next step up. Service life is 30,000 hours at 100 rpm and 30 °C ambient, lubricated for life with no maintenance interval. The -25 to 90 °C operating range covers most indoor industrial environments, though the IP54 shaft output means it should be shielded from pressurized washdown or direct water spray.
Sourcing and lifecycle — obsolete, sourced to order
Schneider Electric lists the GBX0800030702D as obsolete. The part is available through independent distribution channels — quantities are confirmed at RFQ, and the pricing reflects the surplus/broker market rather than a factory-direct line. For a BOM freeze or a line-down replacement, the 80 mm frame size and 3:1 ratio are the critical fit dimensions. The black anodized aluminium housing and C45 steel shaft are standard for this class; any replacement must match the 80 mm diameter, the 3:1 ratio, and the 85 N.m continuous torque rating to drop in without mechanical rework.
