Shaft Loads External radial shaft loads
H1 pumps are designed with bearings that can accept some external radial loads.
The external radial shaft load limits are a function of the load position and orientation,
and the operating conditions of the unit. External radial shaft loads impact lifetime.
For lifetime calculations please contact Sauer-Danfoss representative.
The maximum allowable radial load (R
e
) is based on the maximum external moment
(M
e
) and the distance (L) from the mounting ange to the load. It may be determined
using the following table and formula.
R

= M

/ L
