The GBX0600160554F is a 60 mm planetary gearbox with straight-cut teeth, delivering a continuous output torque of 44 N.m at 100 rpm and a maximum intermittent torque of 70 N.m at the same speed. The 16:1 reduction ratio steps down motor speed while multiplying torque — a common ratio for indexing tables, conveyor drives, and pick-and-place axes where the load inertia is moderate and positioning repeatability matters. Rated service life is 30,000 hours at 100 rpm and 30 °C ambient, with the gearbox lubricated for life — no maintenance schedule for oil changes. The torsional rigidity of 2.5 N.m/arcmin means the gearbox resists windup under load; combined with a maximum backlash of 20 arcmin, this defines the positioning accuracy ceiling for the axis. For applications requiring tighter repeatability, a lower-backlash planetary stage would be needed.
Lifecycle reality — obsolete, sourced through independent channels
For a line-down replacement or a BOM freeze, the practical path is to quote the exact GBX0600160554F against the remaining stock in the independent channel. If the application allows a design change, a current-production planetary gearbox with the same 60 mm frame size and 16:1 ratio from another manufacturer would be the alternative, but that requires mechanical and thermal requalification.
Mechanical interface and environmental limits
The gearbox housing is black anodized aluminium, 60 mm external diameter, with a C 45 steel output shaft. The shaft output seal is rated IP54 — splash-resistant but not submersible; suitable for dry indoor environments or enclosures where washdown is not directed at the shaft seal. Ambient operating range is -25 °C to 90 °C, covering most industrial cabinet and machine-mount conditions. Maximum axial force on the output shaft is 450 N for the 30,000-hour service life, rising to 600 N if the duty cycle is shortened to 10,000 hours. Maximum radial force (applied at mid-shaft) is 340 N for the full life, 500 N for the reduced life. These limits govern the overhung load a pulley, sprocket, or coupling can apply without shortening gearbox life — a common oversight when retrofitting a larger-diameter pulley.
Efficiency and noise — what 94 % and 58 dB mean on the line
At 94 % efficiency, the GBX0600160554F loses about 6 % of input power as heat — for a 44 N.m output at 100 rpm (about 460 W mechanical), the heat loss is roughly 28 W. This is low enough that the anodized aluminium housing dissipates it without forced cooling in most ambient conditions. The 58 dB noise level at 1 m, no-load, is quieter than a typical AC induction motor at full speed — the gearbox is not the dominant noise source in a drive train unless the motor itself is very quiet.
