It delivers 260 N.m continuous output torque at 100 rpm and 30 °C, and peaks at 416 N.m under the same conditions. The 94 % efficiency means roughly 6 % of the input power is lost as heat through the gear mesh — a figure that holds at rated load and speed, so the thermal rise in the housing stays predictable for a given duty cycle. Service life is specified at 30,000 hours at 100 rpm and 30 °C, with the gearbox lubricated for life — no maintenance schedule for oil changes, which simplifies field installation for a conveyor or indexing axis. ## Sourcing reality — obsolete, no direct replacement on record Schneider Electric lists the GBX1200200551F as obsolete. There is no official successor order code from the manufacturer — the closest functional match requires reviewing the GBX family's current catalog for a planetary gearbox with the same 20:1 ratio, 120 mm frame, and comparable torque rating. The part is sourced through independent distribution against an RFQ. Availability is lot-specific and confirmed at quote time; no stock-holding claim is made here. ## Mechanical limits for the output shaft Maximum axial force on the output shaft is 2100 N at 100 rpm for the 30,000-hour service life, or 2800 N for a 10,000-hour life. Radial force is 1500 N at mid-span for the longer life, 2000 N for the shorter — both at 100 rpm and 30 °C. Torsional rigidity is 13 N.m/arcmin, meaning the shaft twists about 0.077 arcmin per N.m of applied torque — a stiffness figure that matters for positioning accuracy in a servo-driven indexing table. The shaft output carries an IP54 rating — splash-resistant but not washdown-rated. The housing is black anodized aluminium, and the shaft material is C45 steel.","metaTitle":"Schneider Electric GBX1200200551F Planetary Gearbox, 20:1","metaDescription":"Schneider Electric GBX1200200551F planetary gearbox, 20:1 reduction, 260 N.m continuous torque, 94% efficiency.
