Swash Plate - A4VG90

The Swash Plate is a precision hydraulic control element for A4VG90 axial piston pumps. It governs the pump’s displacement by altering the piston stroke angle, providing smooth and efficient hydraulic output control. Built from high-grade alloy steel and ground to exact tolerances, it ensures consistent performance, minimal friction, and long operational life under demanding hydraulic conditions.

Features:

• Specifically designed for Rexroth A4VG90 series pumps.

• Precision-ground surface for optimal piston shoe contact.

• Heat-treated for superior wear and fatigue resistance.

• Rigid structure with balanced geometry for stable operation.

• Direct-fit replacement for reliable OEM-level performance.

Applications:

Used in hydrostatic transmission systems, mobile hydraulic equipment, and industrial applications featuring A4VG90 pumps.

Function:

The Swash Plate translates the rotary motion of the pump’s drive shaft into reciprocating piston movement. By adjusting its inclination angle, it varies the pump’s displacement and flow rate, enabling precise hydraulic power control and smooth system response across various load conditions.
