The very high pressures in axial piston pumps are a challenge for the material and precision of the parts. High-strength materials are increasingly being used for this application. The Wieland materials which have proved successful for many years are presented in the following.

Sleeves
Sleeves in Wieland SA5
Wieland-SA5 is a special brass which has been specially developed for sleeves in axial piston pumps and successfully used in practical applications for many years. The addition of manganese and silicon results in the formation of hard manganese silicides making the material extremely wear-resistant.

Slippers in special brass materials Wieland-SA9 and Wieland-SB7
Slippers not only constitute high-precision bearing elements but are also exposed to extremely high stresses.
The two special brass materials, which form hard silicides due to the addition of manganese and silicon and are therefore highly wear-resistant, also exhibit high fatigue strength. Due to these properties they can be used without problems under high dynamic load and at high operating temperatures.
