Torque and duty ratings that matter
Continuous output torque is 800 N.m (7080.6 lbf.in) at 100 rpm and 30 °C — this is the sustained load the gearbox can carry through its rated 30,000-hour service life. Maximum output torque reaches 1280 N.m (11328.9 lbf.in) at the same speed and temperature, covering peak or intermittent overloads without immediate failure. Torsional rigidity is 41 N.m/arcmin, meaning the shaft twists 1 arcminute for every 41 N.m of applied torque — a stiffness figure that matters for positioning accuracy in servo-driven indexing or pick-and-place axes. Maximum torsional backlash is 10 arc.min — the angular play between input and output when reversing direction. This is a standard precision grade for general motion control; for tighter positioning, a lower-backlash variant would be needed.
Mechanical interface and environmental limits
The gearbox has a 160 mm outer diameter (6.3 in) and uses straight teeth — a simpler, more cost-effective tooth profile than helical, but with slightly higher noise at speed. Noise level is 70 dB at 1 m under no-load — audible but within typical machine-floor limits for a gearbox of this size. Shaft output is rated IP54, meaning it resists dust ingress and splashing water — suitable for most industrial enclosures but not washdown environments. Maximum axial force (Fa) is 6000 N at 100 rpm for the 30,000-hour life, or 8000 N for a 10,000-hour duty cycle. Maximum radial force (Fr) is 4200 N at mid-shaft for the longer life, 6000 N for the shorter. These limits govern how much belt tension or overhung load the output shaft can take.
Efficiency and service life
Efficiency is rated at 94 % — typical for a single-stage planetary gearbox of this ratio. The remaining 6 % is lost to gear mesh friction and bearing drag, mostly dissipated as heat. Service life is 30,000 hours at rated load and speed — roughly 3.4 years of continuous 24/7 operation. The gearbox is lubricated for life, so no maintenance oil changes are needed.
