Beschreibung
Zusammenfassung:	A fluid device includes a housing defining a central bore, a plurality of commutator holes that extend radially outward from the central bore and a plurality of axial passages in fluid communication with the commutator holes. A fluid displacement assembly is in fluid communication with the housing. The fluid displacement assembly includes volume chambers in fluid communication with the axial passages of the housing. An output shaft includes a valving portion disposed in the central bore of the housing. The valving portion includes a first and second lands and a valving land disposed between the first and second lands. The first land cooperates with the central bore to define a first journal bearing and the second land cooperates with the central bore to define a second journal bearing. A coating is applied to the first and second lands of the output shaft. The coating includes a polyamide 11 material.
