Product Overview

This genuine Bosch Rexroth splined drive shaft is a heavy-duty mechanical input component engineered to transmit high rotational torque directly into a hydraulic pump or motor's internal rotating group. Featuring a specialized 1-3/4 inch short spline profile (13T-S), it provides an ultra-compact and highly rigid interface with the primary prime mover or power take-off (PTO). Designed to endure harsh torsional reversals, this shaft maintains uniform rotational tracking to eliminate systemic vibration and deliver uninterrupted volumetric fluid transfer under high physical stress.
