Torque and duty ratings — 32 N.m peak, 20 N.m continuous
The maximum output torque of 32 N.m at 100 rpm and 30 °C defines the overload ceiling — useful for acceleration or momentary peak loads, not sustained running. Continuous output torque is 20 N.m at the same speed and temperature. This is the rating for steady-state duty; exceeding it raises winding temperature and shortens the 30000-hour service life. Efficiency is 94 % at rated conditions, meaning 6 % of input power is lost as heat within the gearbox. For a 20 N.m output at 100 rpm (approx 210 W mechanical), the thermal loss is about 13 W — manageable in free air but relevant in enclosed spaces.
Mechanical integration — 40 mm diameter, IP54 shaft output
The gearbox external diameter is 40 mm, fitting into compact actuator assemblies. Shaft output is protected to IP54, meaning dust ingress is limited and water spray from any direction does not enter the output seal. Shaft material is C45 carbon steel, standard for moderate-load applications. The housing is black anodized aluminium — lightweight and corrosion-resistant for indoor or sheltered outdoor use. Axial and radial force limits are 200 N for 10000-hour life or 160 N for 30000-hour life at 100 rpm. These are the bearing load capacities; exceeding them reduces service life or causes premature failure.
Backlash and precision — 28 arc.min maximum
Maximum torsional backlash is 28 arc.min, which is standard for a straight-tooth planetary gearbox at this price point. For positioning applications requiring less than 0.5° repeatability, a low-backlash or helical-gear sibling would be needed. Torsional rigidity is 1.1 N.m/arcmin — the stiffness under load. A 10 N.m load produces about 9 arcmin of elastic windup, which adds to the backlash when reversing direction.
Environmental and maintenance profile
The gearbox is lubricated for life — no oil changes or regreasing intervals. This simplifies maintenance but means the lubricant's thermal limit sets the upper operating temperature. Noise level is 55 dB at 1 m under no-load conditions. In a quiet control room this is audible but not intrusive; on a production floor it is masked by ambient noise.
