The GBX0600161004F is a straight-tooth planetary gearbox from Schneider Electric's GBX series, with a 60 mm housing diameter and a 16:1 reduction ratio. The continuous output torque is 44 N.m at 100 rpm, and the maximum output torque reaches 70 N.m under the same conditions — the margin above continuous is the headroom for acceleration peaks and short-duration overloads, not a steady-state rating. Efficiency is listed at 94 %, which means about 6 % of the input power is lost as heat inside the gearbox. For a 44 N.m output at 100 rpm, that heat load is manageable without external cooling in most duty cycles, but the 30,000-hour service life at rated load assumes the ambient stays within the -25 to 90 °C operating range. The noise level of 58 dB at 1 m, no-load, is a reference for the gearbox alone — under load the noise rises with torque and speed, and the installation structure (mounting stiffness, coupling alignment) often dominates the audible result.
Backlash, shaft loads, and the IP54 boundary
Maximum torsional backlash is 20 arc.min — this is the angular play between input and output when the direction reverses. For positioning axes that need better than 0.3° repeatability, a lower-backlash gearbox (or a preloaded stage) would be specified; 20 arc.min is typical for general indexing and conveyor drives where the load holds position after the motor stops. The output shaft is C 45 steel, and the housing is black anodized aluminium. The shaft output seal is rated IP54, so the gearbox is protected against dust ingress and splashing water at the output side — the motor-mounted input side depends on the motor's own IP rating for the overall assembly. Maximum axial force on the output shaft is 450 N for the full 30,000-hour life, or 600 N if the application accepts a shorter 10,000-hour life. Radial force limits are 340 N and 500 N respectively, measured at mid-span on the output shaft. These are the bearing-life limits — exceeding them reduces service life faster than the torque derating alone would suggest.
Obsolete — sourcing through independent channels
Schneider Electric lists the GBX0600161004F as obsolete. The gearbox is sourced through independent distribution — quantities are confirmed at RFQ, and availability depends on the remaining stock in the surplus channel. The lubricated-for-life design (no maintenance ports) means any unit sourced should be verified for shelf life and seal condition before installation, since the grease and output seal age even when the gearbox is not run.
