Spur gear motors (straight gear)

RB Series
The so-called 'spur gear' gearbox is suitable for applications where position accuracy is not important. Compared to a planetary gear, the spur gear is typically cheaper to produce and also more quiet. On the other hand, the power density - read the max. output torque - is lower for a given flange size. This construction also exhibits bigger play, which can pose a problem with positioning or left/right movement.
