It delivers 50 N.m continuous output torque at 100 rpm and 30 °C, with a maximum intermittent torque of 80 N.m under the same conditions. This gearbox is now classified as obsolete by the manufacturer. The 50 N.m continuous torque rating at 100 rpm and 30 °C defines the thermal steady-state load the gearbox can carry indefinitely. The 80 N.m maximum torque is the peak capability for short-duration acceleration or shock loads — sustained operation above 50 N.m reduces service life below the 30,000-hour baseline. Maximum torsional backlash is 9 arc-minutes, which sets the positioning repeatability floor in a servo or stepper-driven axis. For applications requiring tighter registration, a lower-backlash gearbox (e.g., 3–5 arc-min) would be needed. Axial force capacity is 1200 N for a 10,000-hour life at 100 rpm, derating to 900 N for the full 30,000-hour service life. Radial force at mid-shaft is 950 N for 10,000 hours or 650 N for 30,000 hours — these limits govern bearing selection in the driven load. Efficiency is listed at 94 %, meaning 6 % of input power is lost as heat within the gearbox. At 50 N.m output and 100 rpm (about 524 W output), the thermal loss is roughly 33 W — this heat must be dissipated through the black anodized aluminium housing to stay within the -25 to 90 °C operating range. ## Sourcing an obsolete planetary gearbox — lifecycle and procurement reality The gearbox is lubricated for life and sealed to IP54 at the shaft output — no field maintenance or re-greasing is required. The C45 steel shaft and anodized aluminium housing are standard industrial materials, and the straight-tooth planetary design is mechanically interchangeable with other 80 mm-frame gearboxes of the same ratio and torque class, though mounting dimensions and keyway sizes should be verified against the mating motor and load. For a BOM line that requires this exact part number, the procurement path is a quoted-to-order RFQ through independent distribution. Availability is lot-specific and confirmed at quote time — no stock-holding claim is made here.","metaTitle":"Schneider Electric GBX0800081003F Planetary Gearbox, 8:1","metaDescription":"Schneider Electric GBX0800081003F planetary gearbox, 8:1 ratio, 50 N.m continuous torque, 94% efficiency.
