20:1 planetary — 44 N.m continuous, 94 % efficient
The GBX0600201403F is a 60 mm planetary gearbox with straight teeth, delivering a 20:1 reduction ratio. Continuous output torque is 44 N.m at 100 rpm and 30 °C; maximum intermittent torque reaches 70 N.m under the same conditions. Efficiency is listed at 94 % — this is the mechanical efficiency at rated load, meaning 6 % of input power is lost to friction and gear mesh heating. The unit is lubricated for life, so no maintenance oil changes are required over its rated 30,000-hour service life at 100 rpm.
Maximum torsional backlash is 20 arc.min — this is the angular play between input and output when reversing direction. For positioning applications requiring repeatability under 0.5°, this gearbox introduces a predictable lost-motion window that the downstream encoder or controller must accommodate. Torsional rigidity is 2.5 N.m/arcmin, meaning the output shaft deflects 1 arcmin for every 2.5 N.m of applied torque before the gear teeth engage fully. Combined with the backlash figure, this gives the system stiffness under load. Maximum radial force on the output shaft is 340 N at mid-shaft for the full 30,000-hour life, or 500 N if the application accepts a 10,000-hour life. Maximum axial force is 450 N for 30,000 hours and 600 N for 10,000 hours. These limits govern belt-drive or direct-coupling loads — exceeding them shortens bearing life. Shaft output is rated IP54 — dust-protected and splash-resistant, but not submersion-rated. The black anodized aluminium housing and C45 steel shaft are suitable for dry indoor environments; washdown zones would require a sealed adapter.
