40 mm planetary gearbox, 5:1 reduction, 14 Nm continuous
The GBX0400050554F is a 40 mm diameter planetary gearbox with straight teeth and a 5:1 reduction ratio, delivering 14 Nm continuous output torque at 100 rpm. Rated efficiency is 94 %, with a noise level of 55 dB measured at 1 m under no-load conditions — suitable for noise-sensitive automation cells.
Torque, life, and mounting constraints
Continuous output torque is 14 Nm at 100 rpm and 30 °C; maximum output torque reaches 22 Nm under the same conditions, giving a 1.57× overload margin for transient loads. Service life is rated at 30,000 hours at 100 rpm and 30 °C — the lubricated-for-life design eliminates periodic re-greasing intervals in that window. Maximum radial force (Fr) at the output shaft is 200 N for a 10,000-hour life or 160 N for the full 30,000-hour rating, both at 100 rpm and 30 °C with force applied at mid-distance on the shaft. Maximum axial force (Fa) mirrors the radial derating: 200 N for 10,000 hours, 160 N for 30,000 hours, at the same speed and temperature. Torsional rigidity is 1 N·m/arcmin, and maximum torsional backlash is 24 arcmin — the latter is the key spec for bidirectional positioning accuracy. Shaft output protection is IP54; the housing is black anodized aluminium with a C 45 steel shaft, and the operating ambient range spans -25 °C to 90 °C.
