With pulsating loads over 4600 psi (315 bar), we recommend the use of a splined shaft (AA2FM 10...250: S, T or U / A2FM 200: A / A2FM 250...1000: Z)
The summ of the pressures at ports A and B may not exceed 10 000 psi / 700 bar (A2F5: 9000 psi / 630 bar)
) Attention : shaft end with drives of radial force loads at the drive shaft (pinion, V-belt drives) necessitate reduction of the nominal
1
pressure to p = 4600 psi (315 bar), please contact us.

when appearing higher forces!
Code explanation
a = distance of Fq from shaft shoulder
F = max. perm. radial force at distance
q max
a (at intermittent operation)
F = max. perm. axial force when
ax max
stationary or when axial piston unit
is running at zero pressure
F /psi (bar) = perm. axial force/psi (bar) operating pressure
ax perm.
The direction of the max. perm. axial force must be noted by
sizes 5...200
–F = increases bearing life
ax
–F = reduces bearing life (avoid if possible)
