Planetary gearbox, 60 mm frame, 25:1 reduction
The GBX0600251404F is a Schneider Electric planetary gearbox with straight teeth, 60 mm external diameter, and a 25:1 reduction ratio. It delivers 40 N.m continuous output torque at 100 rpm, with a maximum of 64 N.m at the same speed. Rated efficiency hits 94 %, meaning about 6 % of input power is lost as heat — relevant for thermal management in a confined cabinet or high-duty-cycle application.
Torque, backlash, and service life at rated speed
Continuous torque is 40 N.m (354 lbf.in) at 100 rpm and 30 °C; the maximum output torque reaches 64 N.m (566.4 lbf.in) under the same conditions. The 20 arc.min maximum torsional backlash defines the positioning repeatability — suitable for indexing or registration applications where that angular slack is acceptable. Service life is rated 30,000 hours at 100 rpm and 30 °C, lubricated for life with no maintenance interval. The shaft output carries IP54 protection — sealed against dust ingress and splashing water, but not submersion. Maximum axial force on the output shaft is 450 N at 100 rpm for the full 30,000-hour life, or 600 N if only 10,000-hour life is acceptable. Radial force at mid-shaft is 340 N for the long-life case, 500 N for the short-life case.
