Eaton 5441 / 5443 — variable displacement axial piston motor 89 cm³
Eaton 5441 and 5443 are variable displacement axial piston motors of the Series 54, complementing closed-loop hydrostatic drives where speed and torque control is required without changing pump output. Servo control allows smooth displacement variation from zero to maximum, providing an optimal balance between speed and tractive effort across different operating modes. Used in hydrostatic drives of wheel loaders, backhoe loaders, asphalt pavers, combine harvesters, winches and industrial conveyor systems.
