60 mm planetary gearbox — 8:1 reduction, 18 N.m continuous
The GBX0600081004F is a 60 mm diameter planetary gearbox from Schneider Electric's GBX series, with a reduction ratio of 8:1 and continuous output torque of 18 N.m at 100 rpm. Rated efficiency is 94 %, with a noise level of 58 dB at 1 m under no-load conditions — the straight-tooth design trades some acoustic smoothness for higher torque density compared to helical gears. Maximum output torque reaches 29 N.m at 100 rpm, with a torsional rigidity of 2.3 N.m/arcmin and maximum backlash of 16 arc.min — figures that matter for positioning accuracy in indexing or pick-and-place applications.
Load ratings and service life at 100 rpm
Service life is rated at 30,000 hours at 100 rpm and 30 °C ambient, with the gearbox lubricated for life — no maintenance re-greasing interval to schedule. Maximum axial force is 450 N at 100 rpm over 30,000 hours (600 N over 10,000 hours); maximum radial force is 340 N at mid-shaft over 30,000 hours (500 N over 10,000 hours). These limits apply at the rated speed and temperature — overspeed or higher ambient derates both.
Obsolete — sourcing through independent channels
Available through independent surplus and broker channels; quantities are lot-specific and confirmed at RFQ. No pin-compatible or footprint-matched replacement exists from the original manufacturer — a functional replacement would require re-evaluating the mounting interface, shaft dimensions, and torque envelope.
Mounting and integration notes
The gearbox has a 60 mm outer diameter black anodized aluminium housing, with a C45 steel output shaft. Straight-tooth planetary design means the input and output axes are coaxial — the motor mounts directly to the input flange, and the output shaft couples to the load via a keyed or clamping connection. Ambient operating range is -25 to 90 °C; the lubricant is factory-filled and sealed for the rated life, so no oil-level checks or breather vents are needed.
