DISK SPRING - A4VG125

The Disk Spring for the Bosch Rexroth A4VG125 axial piston pump provides consistent preload and maintains stable contact pressure within the rotating group assembly. It is essential for ensuring smooth operation, reduced vibration, and maintaining precise axial alignment of key pump components.

Features:

• Compatible with Rexroth A4VG125 axial piston pumps.

• Heat-treated for long fatigue life under dynamic load conditions.

• Maintains uniform pressure across piston shoes and swash plate.

• Corrosion-resistant coating for enhanced protection and service life.

Applications:

Used in hydrostatic drive pumps and closed-loop systems for heavy machinery such as excavators, wheel loaders, and industrial hydraulic systems.

Function:

The disk spring absorbs operational stress and maintains the correct axial force between the cylinder block and valve plate, ensuring leak-free sealing and efficient hydraulic performance throughout the pump’s duty cycle.
