Planetary gearbox for precision motion — 80 mm frame, 9:1 ratio
The GBX0800090701F is a Schneider Electric GBX series planetary gearbox with a straight-tooth design, 80 mm outer diameter, and a 9:1 reduction ratio. Continuous output torque is rated at 130 N.m (1150.6 lbf.in) at 100 rpm and 30 °C, with a maximum intermittent torque of 208 N.m (1841.0 lbf.in) under the same conditions.
The 130 N.m continuous rating at 100 rpm defines the thermal limit for sustained duty — exceeding this raises the gearbox temperature above the design envelope. The 208 N.m maximum covers acceleration peaks and emergency stops. Torsional backlash is 14 arc.min maximum, which is the angular play at the output shaft under reversing load. For positioning axes that reverse direction, this backlash must be within the system's repeatability budget. Rated service life is 30,000 hours at 100 rpm and 30 °C, lubricated for life with no maintenance interval for grease changes. Efficiency is 94 %, meaning 6 % of input power is lost as heat in the gear mesh and bearings — typical for a single-stage planetary with straight teeth.
Load capacities and environmental limits
Maximum axial force Fa is 1200 N at 100 rpm for a 10,000-hour life, derating to 900 N for the full 30,000-hour service life. Maximum radial force Fr is 950 N at 100 rpm (10,000-hour life) or 650 N (30,000-hour life), with the force applied at the midpoint of the output shaft. Noise level is 60 dB at 1 m under no-load conditions — this is the acoustic baseline; loaded operation will be higher depending on the motor and coupling.
Lifecycle status — obsolete, sourced through independent channels
Schneider Electric lists the GBX0800090701F as obsolete. The gearbox is available through independent surplus and broker channels. Housing is black anodized aluminium, shaft material is C45 steel. The gearbox is packed singly.
