Obsolete — what that means for your BOM
Schneider Electric lists the GBX1200091404F as Obsolete. That means the factory no longer builds it. If you need this exact order code, the only channel is independent surplus or broker stock — no factory lead time, no last-time-buy window left. No runaround — just a straight answer on what's out there.
9:1 planetary — torque and duty
This is a straight-tooth planetary gearbox with a 9:1 reduction ratio. The continuous output torque is 210 N.m at 100 rpm; the maximum output torque hits 336 N.m at the same speed — that peak figure is for short-duration acceleration or occasional overloads, not steady running. The service life is rated at 30,000 hours at 100 rpm and 30 °C, which is the L10 bearing-and-gear life under continuous rated torque. If your duty cycle is lighter or intermittent, the life extends; if you're running at the max torque continuously, expect it to shorten. Efficiency is 94 % — a solid number for a straight-tooth planetary. The 6 % loss is mostly gear mesh friction and bearing drag, which shows up as heat. In a sealed, lubricated-for-life box with a black anodized aluminium housing, that heat has to radiate through the housing surface. If you're mounting it in a confined space or running near the max torque, check the ambient temperature stays within the -25 to 90 °C range.
Backlash, loads, and fit
Maximum torsional backlash is 12 arc.min — that's the angular play between input and output when reversing direction. For indexing or positioning applications where you need repeatable stops, 12 arc.min is in the standard-precision range; if your servo loop expects tighter, you'd need a low-backlash or preloaded planetary. The axial force limit is 2100 N at 100 rpm for the 30,000-hour life, or 2800 N for a 10,000-hour life. Radial force at mid-span on the output shaft is 1500 N for 30,000 hours, 2000 N for 10,000 hours. Both drop with speed — the 100 rpm condition is the reference; higher speeds reduce the allowable overhung load. Shaft output IP54 means the seal keeps out dust and splashing water, but it's not submersible or washdown-rated. Shaft material is C45 steel — standard medium-carbon, machinable and weldable if you need to modify the keyway or shaft end.
