The loads indicated are valid for all application directions.

The maximum allowable axial loads are equal to 1/5 of the radial load value shown in the table when applied with the same radial load; if this is not the case, please contact our technical office. If double output shafts are used, the sum of radial loads applicable to the centre lines of the two ends of the shaft must not exceed the value shown in the table below.

The radial loads related to the output speed (n2)=10 are the maximum loads supported by the gear.
