DSD-018A Fixed Displacement Axial Piston Motor

Why D-Swing?
Our D-Swing motors are fixed-displacement, axial piston motors designed for durable and high-performance swing applications. With displacements from 18 cm3 to 250 cm3 [1.1 in3 to 15.3 in3] and a continuous pressure rating of 320 bar [4,641 psi], D-Swing motors are suitable for multiple applications including excavators in a wide tonnage range.
The motors feature an integrated design with a reducer, parking brake and multi-functioning valves, and provide high efficiency with smooth and precise swing movement. Features can meet customized requirements, including the shockless relief valve, anti-reverse valve, and time-delay valve.
