Bearing life H1P 069/078
Maximum external shaft moment based on shaft deflection (both sizes 069/078):
M
e
= 109 N•m [965 lbf•in]
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.
