60 mm planetary gearbox — 5:1 reduction, 40 N.m continuous
The GBX0600051404F is a straight-tooth planetary gearbox from Schneider Electric's GBX series, with a 60 mm housing diameter and a 5:1 reduction ratio. It delivers 40 N.m continuous output torque at 100 rpm (30 °C ambient), with a maximum intermittent torque of 64 N.m under the same conditions. Rated service life is 30,000 hours at 100 rpm and 30 °C, with the gearbox lubricated for life — no maintenance re-greasing interval to schedule.
Torque, backlash, and load ratings that govern the fit
Continuous torque is 40 N.m; the maximum output torque of 64 N.m is the peak limit for intermittent duty — stay within the continuous figure for sustained operation. Maximum torsional backlash is 16 arc.min, which sets the positioning repeatability floor for the driven axis. Maximum axial force (Fa) is 450 N for the 30,000-hour service life, or 600 N if the application accepts a shorter 10,000-hour life. Maximum radial force (Fr) is 340 N for 30,000 hours, 500 N for 10,000 hours — both measured at mid-distance on the output shaft. These are the load limits that define the mechanical interface with the driven load. Torsional rigidity is 2.3 N.m/arcmin — a measure of how much the output shaft twists under load. Higher rigidity means less windup in positioning applications.
Efficiency, noise, and environmental ratings
Rated efficiency is 94 %, meaning 6 % of input power is lost as heat in the gear train — relevant for thermal budgeting in the enclosure. Noise level is 58 dB at 1 m, no-load — a moderate figure for a planetary gearbox of this size. Shaft output seal is rated IP54 — splash protection from the shaft side, but the gearbox body itself is not fully sealed. Ambient operating range is -25 °C to 90 °C. Housing is black anodized aluminium; shaft material is C45 steel.
