Overview of the RSF supermini series
Radial load when the operating point is different
If the operating point of radial load is different, the allowable radial load value is also different.
The relation between radial load position L
R
and allowable radial value F
R
is obtained from the
following formula.
The allowable values must not be exceeded.
