Product Introduction

The 90R75 thrust plate is a key load-bearing component in the Eaton 90 Series axial piston pump. It supports the reaction force from the piston slipper assembly and ensures smooth operation of the swash plate system. The surface precision and hardness of the thrust plate directly affect pump efficiency, operating noise, and service life. Halies manufactures the 90R75 thrust plate using high-strength alloy steel with carburizing, quenching, and precision grinding treatment, providing excellent compression strength, wear resistance, and fatigue durability for high-pressure, heavy-duty applications.
