All external shaft loads affect bearing life. In applications with external shaft loads, minimize the impact
by positioning the load at 0° or 180° as shown in the figure.
Danfoss recommends clamp-type couplings for applications with radial shaft loads.
Contact your Danfoss representative for an evaluation of unit bearing life if you have continuously
applied external loads exceeding 25 % of the maximum allowable radial load (R
e
) or the pump
swashplate is positioned on one side of center all or most of the time.
