The GBX1600201384D is a planetary gearbox in the GBX family with a 20:1 reduction and a 160 mm external housing diameter, so it slots into the standard mid-frame planetary footprint on a servo or stepper drivetrain rather than a right-angle or worm unit. Continuous output torque is rated 800 N.m with a peak of 1280 N.m, and service life is 30000 h at 100 rpm and 30 °C ambient — the duty rating, not the peak number, is what governs whether this unit survives a high-cyclic conveyor or indexing table on a five-year horizon. Torsional rigidity is 41 N.m/arcmin with maximum backlash of 10 arc.min, and the moment of inertia at the input is 6.64 g.cm², which keeps reflected inertia manageable on most mid-size servo motors — confirm the motor's Jm versus the gearbox J reflected by 1/i² before locking the coupling selection.
Radial and axial load at the output shaft
Maximum radial force Fr at mid-distance from the output shaft is 4200 N over the 30000 h life at 100 rpm, or 6000 N over a shortened 10000 h life at the same speed — pushing the rated radial load toward the 10000 h figure trades service life for margin on heavy-overhung loads like chain or pinion drives. Maximum axial force Fa is 6000 N over 30000 h at 100 rpm, rising to 8000 N over 10000 h, so a direct-mounted screw or thrust-bearing arrangement needs its working axial load checked against this ceiling rather than the motor's nominal thrust. Efficiency is 94 % at the rated reduction and noise is 70 dB at 1 m no-load, which is consistent with a straight-cut planetary — quieter than a helical-bevel alternative but not silent, so acoustic enclosure may be warranted in operator stations.
Mounting environment and what the IP54 shaft seal actually protects
IP54 is rated at the shaft output only, meaning the seal guards against dust ingress and splashing water on the output shaft; the housing itself is black anodized aluminium and is not sealed for high-pressure washdown, so this is a general-industrial gearbox rather than a food-and-bev or outdoor-unsheltered fit. The output shaft is C 45 medium-carbon steel and the gearbox is lubricated for life, so there is no scheduled oil change to plan into the maintenance schedule — but the 30000 h figure at 100 rpm is the lubricant's design life, and a continuously higher-speed application will shorten the service interval proportionally.
