Product Overview

This genuine Bosch Rexroth OEM cylinder block assembly (Material Number R902512960) serves as the core rotating group component for the Rexroth A10VO45 and A10VSO45 variable displacement axial piston pump series. Engineered to exact factory tolerances, this central compression group accurately aligns and houses the pump pistons to drive maximum volumetric fluid flow. Precision-machined to prevent internal pressure losses, this heavy-duty assembly restores design-level hydraulic output, controls case drainage spikes, and withstands harsh high-pressure demands across mobile construction and industrial power units.

This complete rotating group sub-assembly comes ready for installation with the essential internal timing components. The internal spring, pins, snap ring, and spacer are included with the cylinder block barrel, saving time and ensuring proper factory tensioning during pump overhaul.
