H1B080AALHBATCPAVNCNNNNNNP040N00NNN Danfoss H1B080 Motor 80cc 450bar

Product Overview

The H1B080AALHBATCPAVNCNNNNNNP040N00NNN and H1B110AAL2BANBPADSKSSA10NP022N00NNN are high-precision, fully interchangeable replacements for the Danfoss H1B series bent-axis variable displacement axial piston motors. Featuring spherical pistons and a bent-axis design with a maximum-to-minimum displacement ratio of 5:1, these motors offer high-speed capability and high starting torque. They are primarily intended for closed-circuit systems but can also be used in open circuits. Displacement is steplessly variable between maximum and minimum (with zero-displacement options available). Every unit undergoes 100% simulated operating condition testing to guarantee exact dimensional, interface, control, and performance interchangeability with original Danfoss H1B080 and H1B110 motors—enabling true drop-in replacement.

Key Technical Advantages

1. High Displacement Ratio (5:1) with Zero-Displacement Capability: Wide range from high torque/low speed to high speed/low torque improves overall machine efficiency and controllability.
2. High Speed and High Starting Torque: Excellent starting torque at maximum displacement combined with very high speeds at minimum displacement suits both precise control and high-speed travel applications.
3. Spherical Piston and Precision Bent-Axis Design: Reduces friction and wear, delivering high volumetric efficiency, long service life, low noise, and reliability under high-pressure and high-speed conditions.
4. Extensive Control and Interface Options: Supports electric proportional, hydraulic, pressure-compensator override, and other controls; optional loop flushing and speed sensors for seamless system integration.
5. Full Interchangeability and Rigorous Testing: 100% simulated condition testing ensures exact match of mounting interfaces, shaft ends, and control ports to original equipment, minimizing downtime and retrofit costs.

Application Areas

• Construction machinery propulsion and swing systems (excavators, loaders, cranes)
• Agricultural and forestry equipment drives
• Material handling and specialty vehicle closed-circuit transmissions
• Mobile equipment requiring high speed and wide displacement-ratio control
• Closed- or open-circuit hydraulic drive systems

Expert Maintenance Tips

• Ensure the housing remains filled with hydraulic fluid at all times; size suction/return lines adequately to prevent cavitation and overheating.
• In closed-circuit applications, correctly set the loop-flushing function to maintain system cleanliness and temperature control.
• Maintain fluid cleanliness at ISO 4406 18/16/13 or better; operate within the recommended viscosity range and replace filters regularly.
• Avoid prolonged simultaneous operation at peak pressure and maximum speed to maximize bearing and piston life.
• Use correct seal kits during service; verify minimum displacement setting and control response times.
• Periodically inspect the speed sensor (if fitted) and shaft end for wear, and keep operating temperatures within recommended limits.
