Application Areas：

• Construction machinery: excavators, loaders, bulldozers, cranes, forklifts (travel drive, working device hydraulic system).

• Agricultural machinery: large tractors, combine harvesters, forestry machinery.

• Mining machinery: rock drilling rigs, underground scrapers, crushers.

• Material handling: port machinery (such as reach stackers), heavy forklifts.

• Industrial hydraulics: large presses, injection molding machines, metallurgical equipment, ship deck machinery.

• Travel machinery drive: as pumps and motors in hydrostatic transmission (HST) systems.

Selection and use considerations：

• System matching: Ensure that the pressure, displacement, and speed range of the selected pump/motor match the system requirements.

• Oil cleanliness: The high-pressure system has extremely high requirements for oil cleanliness. High-precision oil filters must be used and maintenance procedures must be strictly followed to protect precision rolling bearings and friction pairs.

• Installation and maintenance: Strictly follow the manufacturer's instructions for installation, alignment, oiling, and maintenance, especially to ensure that the bearings are fully lubricated.

Advantages：

• High performance: Designed for high pressure and high flow/torque requirements.

• High reliability: Rolling bearing design significantly improves load capacity, efficiency and life under harsh conditions.

• Rugged and durable: Suitable for heavy-duty industrial applications and mobile machinery.

• Efficient: Rolling bearings reduce friction losses and optimize volumetric and mechanical efficiency.

• Dual functionality: Provides pump and motor options to meet the dual needs of system power source and actuator.

• Low noise: Special design and manufacturing process make the product low noise during operation, reducing noise pollution to the working environment.
