Code explanation
a = distance of F from shaft shoulder
q
F = max. perm. radial force at distance a
q max
(at intermittent operation)
±F
= max. perm. axial force when stationary
ax max
or when axial piston unit is running at zero pressure
±F
/bar= perm. axial force/bar working pressure
ax perm.
Optimal force direction of F
By means of appropriate force directions of F
by inside rotary group forces can be reduced. An optimal life
expectation of the bearing can be reached.

sizes 5...200:
- F = increases bearing life
ax
