Lifecycle status — obsolete, sourced via independent channels
The GBX0400201404F: Procurement for this part is handled through independent distribution channels. Quantities are confirmed at RFQ against the specific BOM line; no stock-holding claim is made here.
Mechanical ratings that govern the fit
The GBX0400201404F is a 40 mm diameter planetary gearbox with a 20:1 reduction ratio, delivering 20 N.m continuous output torque at 100 rpm and 30 °C ambient. Service life is rated at 30,000 hours at 100 rpm and 30 °C. The gearbox is lubricated for life, meaning no field re-greasing interval is required within that service window. Efficiency is listed at 94 %, which is typical for a single-stage planetary with straight teeth at this ratio. The noise level is 55 dB at 1 m, no-load — relevant for noise-sensitive environments like laboratory or clean-room conveyor drives.
Integration constraints — shaft loading and sealing
The output shaft is C45 steel with IP54 protection at the shaft output. This is a splash-seal rating, not a submersible one — the gearbox is suitable for dry indoor environments with occasional dust or splash exposure, but not washdown or outdoor service. Maximum radial force Fr is 200 N at mid-distance from the output shaft, rated for 10,000 hours at 30 °C. For the full 30,000-hour service life, the allowable radial force drops to 160 N. Axial force Fa follows the same derating profile: 200 N for 10,000 hours, 160 N for 30,000 hours. These are the load limits that must be checked against the driven pulley or sprocket overhang. Torsional backlash is 28 arc.min maximum. This is a standard-precision planetary — not suitable for servo positioning loops that require arc-minute or sub-arc-minute repeatability, but adequate for indexing, transfer, and speed-reduction applications where the load inertia dominates the positioning error.
