Product Overview

The Bosch Rexroth R910996051 Pressure Pin (cylinder block pin / barrel pin) is a genuine, factory-certified OEM rotating group component engineered for Rexroth A10 85-series variable displacement axial piston pumps. These heavy-duty pins sit inside the center of the cylinder block assembly. Working in direct synchronization with the internal block spring, these pins transmit a constant, precise mechanical force against the spherical ball guide. This continuous axial pressure keeps the cylinder barrel tightly sealed against the valve plate and holds the piston slippers flush against the swashplate face, ensuring immediate pump priming and preventing high-pressure fluid bypass.
