Dual Displacement Inner Five-Star Radial Piston Hydraulic Motor Aks2

The AKS2 is a dual displacement radial piston hydraulic motor featuring an inner five-star design. Unlike single-speed motors, it offers two speed operation by switching between large and small displacement modes, providing flexible torque and RPM control for demanding construction machinery applications.

Yes, the AKS2 inner five-star motor is engineered as a direct replacement for SAI BD series motors with identical mounting flanges, shaft dimensions, and port configurations. It delivers equivalent dual displacement performance at a more competitive price for your hydraulic winch or crane systems.

The AKS2 two speed hydraulic motor achieves speed switching through an internal valve that alternates between full-displacement (high torque, low speed) and half-displacement (low torque, high speed) modes. This dual displacement capability eliminates the need for external gearboxes in crane slewing and winch drives.

This low speed high torque hydraulic motor is widely used in hydraulic winches, crane slewing drives, excavator travel motors, drilling rigs, and marine deck machinery. Its inner five-star radial piston structure handles heavy shock loads while the two speed function optimizes efficiency across varying load conditions.
