The A2FM28 is engineered as a compact and powerful drive component for systems requiring high power density and reliable performance.
Mobile Machinery: Ideally suited for the travel and implement drives of compact excavators, small wheel loaders, telehandlers, and agricultural machinery.
Industrial Applications: Provides efficient rotary drive power for conveyors, winches, mixer drums, fan drives, and various factory automation systems.
Specialized Systems: An excellent choice for applications utilizing energy-saving secondary control or in hydraulic test stands.
1. Optimized Swashplate Design for Smooth Operation
The unit features a proven swashplate design with hydrostatically balanced pistons. This advanced engineering minimizes internal friction and wear, resulting in exceptionally quiet and smooth operation, high volumetric efficiency across a wide speed range, and an extended service life.
2. High Power Density in a Compact Package
The A2FM28 is designed to deliver maximum power from a minimal space. Its compact and lightweight construction allows for flexible and space-saving installation in equipment where envelope size is a critical design constraint.
3. Robust Bearing Concept for High Load Capacity
A heavy-duty bearing system supports the rotating group, enabling the unit to handle significant radial and axial loads from directly coupled gears, chains, or pulleys. This ensures reliable performance and high resilience against the shock loads common in demanding mobile applications.
4. Application Versatility and System Integration
As a key component in closed-circuit systems, the A2FM28 offers great flexibility. Its compatibility with various control and regulation options makes it a fundamental building block for creating efficient, responsive, and intelligent hydraulic drive solutions.
