Planetary gearbox with straight teeth, 12:1 reduction
The GBX0600120583D is a 60 mm diameter planetary gearbox from Schneider Electric's GBX series, offering a 12:1 reduction ratio with straight teeth. It delivers 44 N.m continuous output torque and peaks at 70 N.m maximum, making it a fit for servo-driven positioning axes where compact diameter and moderate torque are needed.
Torque, backlash, and service life
Continuous torque is 44 N.m; maximum output torque is 70 N.m. Torsional backlash is 25 arc.min maximum — typical for a straight-tooth planetary stage, not a zero-backlash unit. Service life is rated 30,000 hours at 100 rpm and 30 °C, lubricated for life with no maintenance interval. Maximum axial force on the output shaft is 450 N at 100 rpm for 30,000 hours, or 600 N for 10,000 hours. Radial force (applied mid-shaft) is 340 N for the longer life target, 500 N for the shorter. Torsional rigidity is 2.5 N.m/arcmin.
Efficiency, noise, and environmental ratings
Efficiency is 94 % at the rated load — typical for a single-stage planetary with straight teeth. Noise level is 58 dB at 1 m, no-load, which is low enough for lab or light industrial environments. The shaft output seal carries IP54 protection; housing is black anodized aluminium, shaft material is C 45 steel.
