Obsolete — what that means for your BOM
Schneider Electric lists the GBX1200081402F as obsolete. If this gearbox is on your BOM, you are looking at the surplus channel — no factory orders, no last-time buy window left. The part is sourced through independent distribution against an RFQ.
8:1 planetary — torque and stiffness numbers
This is a straight-tooth planetary gearbox, 120 mm outer diameter, with an 8:1 reduction ratio. Continuous output torque is 120 N.m at 100 rpm and 30 °C; peak torque hits 192 N.m under the same conditions. Rated service life is 30,000 hours at 100 rpm and 30 °C. The gearbox ships lubricated for life — no oil changes, no maintenance schedule on the lube.
Load ratings — axial and radial limits
Maximum axial force Fa is 2100 N at 100 rpm for the 30,000-hour life rating, or 2800 N if you accept a 10,000-hour service life. Radial force Fr at the output shaft mid-point is 1500 N for the longer life, 2000 N for the shorter. The shaft output carries an IP54 protection rating — splash-resistant but not washdown. The housing is black anodized aluminium; the shaft is C45 steel.
Efficiency and noise — what 94 % and 65 dB mean on the line
Efficiency is listed at 94 % — that is the power throughput at rated load, not a no-load spin loss figure. For a 120 N.m continuous output, expect about 7.6 N.m of input loss at the motor side. Noise level is 65 dB at 1 m, no-load. With load the gear whine rises a few dB, but this is a quiet unit for a straight-tooth planetary — comparable to a helical in the same torque class.
Operating range and physical fit
The 120 mm diameter and 8:1 ratio mean it replaces a same-frame GBX gearbox with the same mounting pattern — measure the input shaft and bolt circle before ordering.
