Planetary construction packs high torque density into a compact cylindrical housing — the 80 mm diameter fits where a parallel-shaft gearbox of equivalent ratio would be wider. Continuous output torque is 120 N·m at 100 rpm and 30 °C ambient — this is the duty rating for sizing. Maximum output torque reaches 192 N·m under the same conditions, but that figure is for short-duration peaks, not steady operation. The 30000-hour service life at rated load means the gearbox is designed for a three-shift year of continuous running before bearing or gear wear reaches end-of-life. Efficiency is listed at 94 %, which is typical for a single-stage planetary at this ratio. The 6 % loss is mostly gear mesh friction and churning — it appears as heat in the housing, so the black anodized aluminium body acts as the heat sink. No external cooling is required at the rated torque and speed. ## Backlash, stiffness, and load limits — the mechanical constraints that govern integration Maximum torsional backlash is 16 arc-minutes. That is standard precision for a general-purpose planetary — adequate for indexing, conveyor drives, and rotary tables where position repeatability is not sub-arcminute. For servo positioning with encoder feedback, the backlash is absorbed by the control loop, but the dead band will show in the first few counts of a move. Torsional rigidity is 6.3 N·m per arc-minute. This number tells you how much the output shaft twists under load — at 120 N·m continuous, the wind-up is about 19 arc-minutes of elastic deflection on top of the 16 arc-minute backlash. The combination means the output position under full load can be up to 35 arc-minutes from the no-load position, which matters for applications like cam indexing where the load angle must be predictable. Maximum axial force on the output shaft is 1200 N at 100 rpm for a 10000-hour life, dropping to 900 N for the full 30000-hour rating. Maximum radial force is 950 N at 100 rpm for 10000 hours, or 650 N for 30000 hours. These limits apply with the force applied at the mid-point of the output shaft — a belt or pulley overhung load must be calculated from the shaft extension length, not just the radial force number. ## Obsolete — sourced through independent distribution Schneider Electric lists the GBX0800800554F as obsolete. The part is available through independent surplus and broker channels — quantities are lot-specific and confirmed at RFQ. The gearbox is lubricated for life, so there is no maintenance schedule for grease changes. The IP54 rating on the shaft output means the seal keeps out dust and splashing water, but the gearbox is not rated for washdown or submersion — it belongs inside an enclosure or under a drip shield in wet environments.","metaTitle":"Schneider Electric GBX0800800554F Planetary Gearbox, 80:1","metaDescription":"Schneider Electric GBX0800800554F planetary gearbox, 80:1 reduction, 120 N·m continuous torque, 94% efficiency, IP54.
