Product Overview

The Bosch Rexroth Retainer Plate is a genuine OEM rotating group component designed for high-pressure, closed-circuit axial piston pumps. Specifically built for Rexroth A4VG71 and A4VTG71 series units, this retaining plate plays a critical role in the pump's mechanical integrity. It continuously presses the piston slipper pads flat against the swashplate surface. This secure contact prevents piston lift-off during low-pressure cycles, eliminates internal mechanical play, and protects the entire rotating group from catastrophic failure under heavy workloads.
