Torque and duty ratings that matter
The GBX0600250704F is a 60 mm planetary gearbox with a 25:1 reduction ratio, delivering a continuous output torque of 40 N.m (354.03 lbf.in) at 100 rpm and 30 °C. Efficiency is listed at 94 %, which is typical for a single-stage planetary with straight teeth — the remaining 6 % is lost to gear mesh friction and bearing drag. Noise level at no-load is 58 dB measured at 1 m, quiet enough for indoor automation cells without acoustic enclosures.
Mechanical limits and service life
Service life is rated at 30,000 hours at 100 rpm and 30 °C — the gearbox is lubricated for life, so no maintenance interval for oil changes. Maximum axial force on the output shaft is 450 N for the full 30,000-hour life, or 600 N if the application accepts a shorter 10,000-hour life. Radial force limits are 340 N and 500 N respectively, with the force applied at mid-distance from the output shaft. Torsional rigidity is 2.5 N.m/arcmin, and maximum torsional backlash is 20 arc.min — this is a standard-precision planetary, not a zero-backlash unit. The shaft output seal is rated IP54, suitable for dry indoor environments but not washdown. Ambient operating range is -25 to 90 °C.
