・Accurate permissible bending and thrust loads are those loads (measured values) with an output error of 0.05% R.O.
・Accurate permissible bending loads are the result of fixing the enclosure and applying the load on the axis of rotation 33 mm from the enclosure end face.
・All values are guaranteed for static loads.
