Obsolete — sourcing reality for this 9:1 planetary gearbox
The GBX0600091403F is officially obsolete per Schneider Electric's lifecycle status. No direct successor is listed, so procurement relies on independent distribution channels — quantities and pricing confirmed per RFQ against your BOM line. This is a straight-tooth planetary gearbox with a 60 mm housing diameter, reduction ratio 9:1, and continuous output torque rated at 44 N.m at 100 rpm, 30 °C ambient. Maximum peak torque hits 70 N.m under the same conditions — useful for intermittent overloads during acceleration or reversing.
Torque, life, and what the ratings actually mean
Continuous torque of 44 N.m at 100 rpm is the sustained load the gearbox can carry for its full 30,000-hour service life at 30 °C. The maximum torque figure of 70 N.m is a short-duration peak — design the duty cycle so sustained load stays below 44 N.m to avoid accelerated wear. Service life is rated 30,000 hours at 100 rpm, 30 °C. Running at higher speeds or temperatures will reduce that figure — no derating curve is published, so budget conservatively if your application exceeds those conditions. The gearbox is lubricated for life, meaning no scheduled oil changes, which simplifies maintenance in sealed drives. Maximum axial force on the output shaft is 450 N for the full 30,000-hour life, or 600 N if you accept a shorter 10,000-hour life. Radial force at mid-shaft is 340 N for 30,000 hours, 500 N for 10,000 hours. These limits govern bearing life — overshoot them and the gearbox fails before the rated hours. Torsional rigidity is 2.5 N.m/arcmin — a measure of how much the output shaft twists under load. For positioning applications, this stiffness plus the 20 arcmin maximum backlash determines the total lost motion. If your axis needs better than 20 arcmin repeatability, this gearbox may need a preloaded or low-backlash variant.
Efficiency, noise, and environmental fit
94% efficiency means 6% of input power is lost as heat — typical for a single-stage planetary. At 44 N.m output and 100 rpm, that's about 28 W of heat to dissipate through the black anodized aluminium housing. In a confined enclosure, check that the ambient stays within the -25 to 90 °C operating range. Noise level is 58 dB at 1 m, no-load — quiet enough for indoor machinery near operators. The straight-tooth design is inherently noisier than helical, but at this size and ratio the noise is moderate. Under load the level will rise, but no loaded figure is published. Shaft output is rated IP54 — protected against dust ingress and splashing water from any direction. The housing itself is not sealed, so the gearbox should not be washed down directly. The C45 steel output shaft is standard for this class; in corrosive environments, consider adding a shaft seal or specifying a stainless variant if available.
Sourcing this obsolete part — what to expect
With no official successor from Schneider Electric, the GBX0600091403F is sourced through independent surplus and broker channels. Availability is lot-specific — confirmed at RFQ against your quantity. No pin-compatible direct replacement is listed, so if you need a functional equivalent, a parametric search for 60 mm planetary gearboxes with 9:1 ratio and 44+ N.m continuous torque will identify candidates that may require mounting or shaft adaptations.
