Information About 74328-DAB
The 74328-DAB is part of Eaton’s 743XX series of fixed-displacement axial piston motors, designed for medium-duty hydraulic applications in industrial and mobile equipment. With a displacement of approximately 49 cm³/rev (3.00 in³/rev), it delivers reliable torque output, bi-directional rotation, and high-speed performance up to 3000 rpm. Its compact SAE-B flange and spline shaft design support easy integration into a wide range of systems requiring consistent hydraulic power. Built for durability, it operates under pressures up to 315 bar (4568 psi) and is field-serviceable for reduced maintenance downtime.
Key Features:
- Fixed Displacement Design: Provides predictable, constant torque and flow delivery for stable hydraulic operation.
- Compact Power: ~49 cm³/rev displacement in a lightweight housing, ideal for confined installations or mobile use.
- High Pressure Rating: Supports up to 315 bar (4568 psi), suitable for continuous and demanding duty cycles.
- Speed Capability: Operates efficiently at speeds up to 3000 rpm for fan drives, conveyors, and hydraulic systems.
- Bi-directional Rotation: Supports flexible circuit configurations for both forward and reverse flow applications.
- SAE-B Mounting: Standard two-bolt flange mount and 13-tooth spline shaft for quick, secure installation.
- Rear Porting: Includes SAE O-ring ports for work and case drain connections, simplifying plumbing and reducing leak risk.
- Durable Construction: Precision engineering ensures long life under variable load and temperature conditions.
- Serviceable Design: Allows for convenient maintenance and field replacement to minimize downtime.
- Versatile Applications: Used in agriculture, construction, automation, and industrial hydraulic systems.
The Eaton 74328-DAB is a dependable choice for compact hydraulic motor needs where fixed torque, space efficiency, and rugged design are essential.
