Product Overview

The Bosch Rexroth Drive Shaft is a genuine OEM high-torque input component specifically designed for Rexroth A4VG56 Series 32 variable displacement axial piston pumps. Configured exclusively for 32 design units, this heavy-duty shaft features a metric 30 mm diameter with a 14-tooth splined front end to act as the primary mechanical link for system power transmission. Forged from high-tensile, wear-resistant alloy steel, it efficiently transfers massive rotational torque while isolating mechanical vibrations and resisting shear fatigue under aggressive startup loads.
