Product Overview

The Bosch Rexroth R909921902 Drive Shaft (T) is a heavy-duty, factory-original OEM component designed for high-torque hydraulic rotating groups. Specifically engineered for Rexroth A4VG71 and A4VTG71 axial piston units, this through-drive (T) shaft transfers primary mechanical input while synchronizing power to auxiliary rear pump systems. Constructed from induction-hardened, high-tensile alloy steel, it is built to survive intensive continuous operations, minimize micro-fretting along spline interfaces, and prevent costly drivetrain downtime.
