Planetary gearbox, 60 mm, 4:1 — obsolete, sourced per RFQ
The GBX0600041003F is a Schneider Electric planetary gearbox with straight teeth, 60 mm external diameter, and a 4:1 reduction ratio. It delivers 38 N.m continuous output torque at 100 rpm and 30 °C, with a maximum of 61 N.m under the same conditions. Rated for 30000 hours service life at 100 rpm and 30 °C, the gearbox is lubricated for life and sealed to IP54 at the shaft output — suitable for applications where occasional washdown or dust exposure occurs but the gearbox is not submerged. Schneider Electric lists this part as obsolete.
Continuous output torque of 38 N.m (336.3 lbf.in) at 100 rpm and 30 °C is the sustained rating — the gearbox can run at this load indefinitely within the 30000-hour service life. Maximum output torque of 61 N.m (539.9 lbf.in) is the peak allowable for intermittent duty, not continuous operation. Maximum torsional backlash is 16 arc.min — this is the angular play between input and output when reversing direction. For positioning applications requiring less than 0.27° of lost motion, a lower-backlash gearbox (e.g. 8 arc.min or less) would be needed. Axial force limit is 450 N for the full 30000-hour life at 100 rpm and 30 °C, or 600 N for a reduced 10000-hour life. Radial force limit is 340 N for 30000 hours, 500 N for 10000 hours, both measured at mid-span on the output shaft. These limits govern the overhung load the gearbox can support from a belt, chain, or direct coupling. Efficiency is 94 % — typical for a single-stage planetary with straight teeth. Noise level is 58 dB at 1 m, no-load, which is quiet enough for most production environments without additional enclosure damping.
Integration and environmental limits
The gearbox housing is black anodized aluminium, 60 mm diameter, with a C 45 steel output shaft. Ambient operating range is -25 to 90 °C, covering most indoor industrial settings and some outdoor enclosures. Shaft output IP54 means the gearbox is protected against dust ingress and splashing water — adequate for machine-tool coolant splash or washdown zones, but not for immersion or high-pressure spray. The gearbox is lubricated for life and requires no maintenance access ports. Torsional rigidity is 2.3 N.m/arcmin — this stiffness figure affects the system's natural frequency and positioning accuracy under load. For servo-driven axes, the combined stiffness of the gearbox and coupling determines the achievable bandwidth.
