Ball Guide - A4VG90

The Ball Guide is a precision-machined component used in A4VG90 axial piston pumps. It maintains the correct alignment of the piston shoes within the rotating group, ensuring smooth motion and consistent contact with the swash plate. Made from high-strength bronze alloy, it offers excellent wear resistance, dimensional stability, and long-lasting performance in high-pressure environments.

Features:

• Designed for Rexroth A4VG90 axial piston pumps.

• Bronze alloy construction for superior durability and anti-friction performance.

• Precision-machined internal spline for accurate piston shoe positioning.

• High load-bearing capacity for reliable operation under extreme pressure.

• OEM-quality finish for direct replacement and easy installation.

Applications:

Commonly used in hydrostatic drives, industrial hydraulic systems, and mobile machinery utilizing A4VG90 series pumps.

Function:

The Ball Guide ensures that the piston shoes remain correctly aligned and evenly distributed around the cylinder block. It allows smooth pivoting motion during operation, reducing wear on pistons and shoes while maintaining efficient hydraulic output and balanced pump performance.
