Overview of the RSF supermini series
1-11 Allowable load
Allowable radial load and allowable thrust load
The gear head used in the RSF supermini series incorporates the high-precision 4-point contact ball
bearing for direct support of external load (output part).
The allowable radial load and thrust load of the output
shaft are shown below.
The allowable radial load F
r
is obtained with respect
to the center (L/2) 0 point of the output shaft.
The values in the following table are designed by
considering the life of the bearing.
The allowable values must not be exceeded.
