The GBX0600120552F is a 60 mm-diameter planetary gearbox with a 12:1 reduction ratio. That 12:1 means the output shaft turns once for every twelve input revolutions — torque multiplies by roughly the same factor, minus the 94 % efficiency loss. The continuous output torque is 44 N.m at 100 rpm and 30 °C; the maximum output torque (short-term, same speed and temperature) is 70 N.m. Planetary construction (coaxial input/output, torque split across multiple planet gears) gives this form factor a higher torque density than a parallel-shaft box of the same diameter. The straight-tooth gear set keeps cost down but produces more audible whine than a helical — the noise level is 58 dB at 1 m, no-load.
Service life, backlash, and the lubrication detail
Rated service life is 30,000 hours at 100 rpm and 30 °C ambient. That's about 3.4 years of continuous running — a solid baseline for a pick-and-place axis or conveyor drive that runs one shift. The maximum torsional backlash is 20 arc.min, which is standard precision for a straight-tooth planetary; reversal applications (positioning with load reversal) will see that much lost motion before the output engages. The gearbox is lubricated for life — no oil-change interval, no breather, no level check. The shaft output seal is rated IP54, so it keeps out dust and splash but isn't rated for washdown. Housing is black anodized aluminium; shaft material is C45 steel.
Obsolete — sourcing through independent channels
Schneider Electric lists the GBX0600120552F as obsolete. The part is available through independent surplus and broker channels — quantities are lot-specific and confirmed at RFQ. No pin-compatible or dimensionally identical drop-in replacement is documented by Schneider.
