15:1 planetary reduction with 94 % efficiency
The GBX1200151401F is a Schneider Electric planetary gearbox with a 15:1 reduction ratio, straight-tooth gearing, and a 120 mm housing diameter. It delivers a continuous output torque of 230 N.m and a maximum output torque of 368 N.m at 100 rpm and 30 °C. Rated efficiency is 94 %, meaning roughly 6 % of input power is lost as heat through the gear mesh — a typical figure for a single-stage planetary set with straight teeth. The noise level at 1 m under no-load is 65 dB, which is audible but not intrusive in a machine enclosure.
Torque, backlash, and service life at 100 rpm
Maximum torsional backlash is 12 arc.min — this is the angular play at the output shaft when the input is reversed. For positioning applications that need tighter repeatability, a lower-backlash gearbox would be required; 12 arc.min is standard for general motion transmission. Service life is rated at 30,000 hours at 100 rpm and 30 °C, with the gearbox lubricated for life — no maintenance oil changes. The shaft output seal carries IP54 protection, meaning it resists dust ingress and splashing water, but is not rated for washdown or submersion. Maximum axial force on the output shaft is 2100 N for the 30,000-hour life target, or 2800 N if the application accepts a shorter 10,000-hour life. Maximum radial force applied at mid-distance on the output shaft is 1500 N for 30,000 hours, or 2000 N for 10,000 hours.
Obsolete — sourcing through independent channels
Schneider Electric has marked the GBX1200151401F as obsolete. This gearbox is available through independent surplus and broker channels. No pin-compatible direct replacement exists from Schneider — a functional equivalent would need to match the 120 mm diameter, 15:1 ratio, 230 N.m continuous torque, and 12 arc.min backlash.
