Doosan DH258 Swing Motor Assy

The Doosan DH258 Swing Motor Assy in the full hydraulic excavator is a key component of the slewing mechanism. It can convert the oil pressure provided by the main pump into mechanical energy and input it to the gearbox. The quality of its work performance will directly affect the rotation speed, drive torque, rotation parking and parking brake of the whole machine, which is the key to determining the productivity of the whole machine. Swing motors are divided into two categories: low-speed high-torque motors and high-speed swing motors.
