You can accumulate more than one optional part. For more details, consult your Poclain Hydraulics application engineer.
Fluorinated elastomer seals: nitrile seals marked in the figure below replaced by fluorinated elastomer seals.

Installed speed sensor or predisposition 
Brake environmental cover without plug: no plug or hole in the cover.

Drainage: additional drain in the cover.
Industrial support: reduction of around 50% from the rated value in the bearings' preload value. .
Diamond™ : special treatment of the motor core which considerably increases its strength, making the motor much more tolerant to temporary instances of the operating conditions being exceeded.
Hollow shaft:

Drain on the bearing support
Abrasive environments (mechanical seal): some environments can be very harmful. The mirror seal gives reinforced motor sealing.
Reinforced sealing: requires reinforced seals and, for an unbraked motor, a rear reinforced plate
Special wheel rim mounting: enables certain combinations different from the standard mountings
High efficiency: reinforced piston sealing to improve volumetric efficiency.
Reinforced bearing stop: heat treatment on the indicated bearing radius and splines, see figure below.

Treated shaft: heat treatment on the splines, see figure below.

High speed: under certain conditions, an increase in the maximum speed of 30%.
Soft Shift™: progressive displacement change (cushioned slide-valve)
