Product details

Planetary gearbox with 20:1 reduction and 260 N.m continuous torque

The GBX1200200703F is a Schneider Electric planetary gearbox with straight teeth, a 120 mm outer diameter, and a 20:1 reduction ratio. It delivers 260 N.m continuous output torque at 100 rpm and 30 °C, with a maximum of 416 N.m under the same conditions. Rated efficiency is 94 %, and the gearbox is lubricated for life — no scheduled oil changes over its 30,000-hour service life at rated load.

The 260 N.m continuous torque at 100 rpm sets the thermal limit for steady-state positioning or conveying loads. The 416 N.m peak covers acceleration transients and occasional overloads, but sustained operation above the continuous figure shortens the 30,000-hour service life. Maximum torsional backlash is 12 arc.min — this is the lost motion at the output under reversing load. For applications needing tighter positioning repeatability, a lower-backlash gearbox (e.g., 3–5 arc.min) would be required. Torsional rigidity of 13 N.m/arcmin means the output shaft twists 1 arc-minute per 13 N.m of applied torque; this stiffness figure governs the windup under load in servo-driven indexing.

Mounting, sealing, and environmental limits

The shaft output seal is rated IP54 — splash-proof from the output side, but the gearbox body is not sealed for washdown. Ambient operating range is -25 to 90 °C; the lubricant is factory-filled and sealed for life, so no field greasing is needed. Shaft material is C45 carbon steel. Maximum axial force (Fa) is 2100 N at 100 rpm for the 30,000-hour life target, or 2800 N if you accept a 10,000-hour service interval. Maximum radial force (Fr) applied at mid-span on the output shaft is 1500 N for 30,000 hours, 2000 N for 10,000 hours. Noise level is 65 dB at 1 m, no-load — typical for a straight-tooth planetary of this size. The black anodized aluminium housing dissipates heat through the 120 mm diameter shell; no external cooling is required at the rated duty.

Obsolete — sourcing through independent channels

Schneider Electric has marked the GBX1200200703F as obsolete.

Frequently asked questions

What is the continuous torque rating of the GBX1200200703F?

260 N.m at 100 rpm and 30 °C. The maximum output torque is 416 N.m under the same conditions, but sustained operation above the continuous figure reduces the 30,000-hour service life.

What does the 12 arc.min backlash mean for positioning accuracy?

12 arc.min of maximum torsional backlash means the output shaft can rotate up to 0.2 degrees before engaging the load when reversing direction. For applications requiring tighter repeatability — such as indexing tables or pick-and-place axes — a gearbox with 3–5 arc.min backlash would be a better fit.
