Under no-load conditions and an ambient temperature of 25°C,when the output shaft speed is 0,measurement values for different modules may vary. These data are for reference only.

For collaborative robots with a 10kg load,under normal operating conditions, the surface temperature of the sixth axis may vary between different modules and environments.These values are for reference only.

Based on the lifespan calculation formula $$Lh=Ln{\left(\frac{Tr}{Tay}\right)}^3\cdot \left(\frac{Nv}{Nav}\right)$$.
taking the fourth axis of a 10kg collaborative robot as an example:

Due to the reduced weight of the last three eRob80 joints,the load on the fourth axis decreases, thereby enhancing its lifespan:

$Lhv5=Ln{\left(\frac{Tr}{14.1\times 0.082\times 9.8}\right)}^3\cdot \left(\frac{Nv}{Nav}\right)$

$Lhv6=Ln{\left\{\frac{Tr}{[14.1-(0.16+0.05)\times 2]\times 0.082\times 9.8}\right\}}^3\cdot \frac{Nv}{Nav}$

The lifespan of the eRob 80I V6 can be increased by 9.5%.
