60:1 reduction, 416 N·m peak — obsolete but available
The GBX1200600701F is a planetary gearbox with straight teeth, 60:1 reduction, and a 120 mm housing diameter. Continuous output torque is 260 N·m at 100 rpm and 30 °C; maximum output torque reaches 416 N·m at the same speed and temperature. Maximum torsional backlash is 14 arc-min — this sets the positioning repeatability floor for indexing or servo-driven rotary tables. Torsional rigidity is 12 N·m/arcmin, which governs how much angular deflection the gearbox allows under load.
Lifecycle and sourcing — obsolete, quoted to order
Schneider Electric lists the GBX1200600701F as obsolete. Available through independent surplus and broker channels.
Rating context for a motion-control gearbox
The 260 N·m continuous rating at 100 rpm and 30 °C defines the thermal steady-state limit for a duty cycle that stays below the gearbox's service life of 30,000 hours. The 416 N·m maximum rating covers peak overloads — for acceleration or intermittent loads — but the 30,000-hour life figure applies at the continuous torque. Efficiency is 90 %, typical for a single-stage planetary with straight teeth. The 14 arc-min backlash is moderate — suitable for general positioning but not for zero-backlash applications (harmonic drives or preloaded planetary stages would be needed for tighter repeatability). Shaft output IP54 means the output seal handles dust and splashing water — not submersion. Lubricated for life, so no maintenance oil changes. Ambient operating range is -25 to 90 °C.
