Planetary gearbox, 60 mm frame, 4:1 reduction — now obsolete
The GBX0600041401F is a 60 mm-diameter planetary gearbox from Schneider Electric's GBX series, with a 4:1 reduction ratio and straight-cut teeth. It delivers 38 N.m continuous output torque at 100 rpm, with a maximum intermittent torque of 61 N.m under the same conditions. Schneider has marked this unit obsolete — no official successor is listed. For a line-down replacement, the sourcing path is independent distribution, with quantities confirmed per RFQ.
Torque, backlash, and service life at rated speed
Continuous output torque is 38 N.m (336.3 lbf.in) at 100 rpm and 30 °C; maximum output torque reaches 61 N.m (539.9 lbf.in) under the same conditions. Torsional rigidity is 2.3 N.m/arcmin, and maximum torsional backlash is 16 arc.min — a figure to check against your positioning budget. Rated service life is 30,000 hours at 100 rpm and 30 °C. The gearbox is lubricated for life, so no field re-greasing interval. Maximum radial force at the output shaft mid-point is 340 N for the 30,000-hour rating, 500 N for a 10,000-hour duty cycle. Shaft output sealing is IP54 — suitable for dry indoor environments but not washdown. The housing is black anodised aluminium; the shaft is C45 steel.
Efficiency and noise — what the numbers mean for a motion axis
Listed efficiency is 94 % — typical for a single-stage planetary with straight teeth at this ratio. The 6 % loss is mostly gear mesh friction and bearing drag; it translates into heat that must be dissipated through the 60 mm aluminium housing. Noise level is 58 dB at 1 m, no-load — roughly the hum of a quiet office printer. Under load the noise rises with torque and speed; straight-cut teeth are inherently noisier than helical, so if acoustic specs are tight this is a factor to confirm on your actual axis.
