Product Overview
The 90M130NC0N8NOF1W00NNN000024 is a swashplate-type axial piston fixed motor from the Danfoss (formerly Sauer-Danfoss) Series 90 family. Featuring a proven swashplate design, this fixed-displacement, high-power-density axial piston motor is engineered for closed-circuit hydrostatic transmissions.
The 90M series offers multiple displacement options including 42, 55, 75, 100, and 130 cc/rev. The 90M130, as the largest displacement model in the series, is recognized for its compact construction, exceptional reliability, and high power density—widely deployed in hydrostatic travel drives for combine harvesters, rollers, forwarders, and other mobile machinery.
Designed as a 100% interchangeable direct replacement for the original Danfoss 90M130NC0N8NOF1W00NNN000024, this product matches OEM specifications in mounting dimensions, porting interfaces, and performance characteristics. Every unit undergoes 100% simulated duty cycle testing prior to shipment, validating volumetric efficiency, mechanical efficiency, and sealing integrity under actual operating load conditions.

Key Technical Advantages
1. Swashplate Fixed Displacement Design – High Efficiency and Reliability
The 90M series employs a proven swashplate axial piston architecture. The fixed displacement design eliminates the complexity of variable mechanisms, providing superior reliability and extended maintenance intervals under extreme operating conditions. Exceptional total efficiency and high starting efficiency ensure excellent performance during both startup and continuous operation.
2. High Power Density – Compact Size with Exceptional Pressure Capability
With a displacement of 130 cc/rev in a compact footprint, the motor delivers rated pressure up to 420 bar and peak pressure up to 480 bar. This high power density makes it ideal for space-constrained mobile equipment requiring high-pressure and high-torque output.
3. 100% Interchangeability – Zero-Modification Drop-In Replacement
Manufactured to exact OEM mounting dimensions, porting specifications, and performance standards, this motor achieves 100% interchangeability with the original Danfoss 90M130NC0N8NOF1W00NNN000024. No machine modifications are required—simply replace and resume operation, minimizing downtime and reducing maintenance costs.
4. 100% Simulated Duty Cycle Testing for Extreme Environment Reliability
Every motor undergoes 100% simulated duty cycle testing before shipment, validating performance under rated pressure (420 bar), peak pressure (480 bar), and maximum speed conditions—ensuring long-term reliability in demanding agricultural, construction, and mobile applications.
5. Wide Speed Range with Closed-Circuit Optimized Design
This model supports a wide speed range from 500 to 3900 rpm, meeting both low-speed high-torque and high-speed light-load requirements. Optimized for closed-circuit operation with an integrated flushing valve option that effectively reduces system oil temperature and extends component service life.
6. Modular Configuration for Versatile Application Adaptation
The 90M series offers multiple shaft types, port configurations, flushing valve options, and speed sensor options. This modular design enables rapid adaptation to combine harvesters, rollers, forwarders, mining equipment, and other diverse applications.
7. Robust Construction for Long Service Life
Engineered with a rugged overall design and high-quality materials, with critical friction pairs precision-machined for continuous high-load operation. Optimized piston-swashplate interaction reduces friction losses and extends motor service life.

Expert Maintenance Tips
Pre-Installation Preparation: Before using the 90M series motor, read and understand the complete Danfoss Series 90 Axial Piston Motors Technical Information Manual. For first commissioning, fill the motor housing with hydraulic fluid using a filling unit with filtration not less than 10 µm. Never operate the motor without fluid.
Oil Cleanliness Control: 90M series motors require high fluid cleanliness. Recommended system filtration not less than ISO 4406 18/13. Regular oil analysis is recommended with filter change intervals adjusted based on contamination levels.
Case Drain Pressure Monitoring: Regularly monitor case drain pressure to ensure it remains within design limits, preventing excessive housing pressure that could damage shaft seals.
Coupling Alignment: Precise alignment between the motor shaft and drive shaft is required with minimal tolerance. After installation, manually rotate the coupling to verify smooth operation.
Flushing Valve Maintenance: For models equipped with flushing valves, regularly inspect the valve’s cracking pressure and flow rate to ensure adequate oil cooling and filtration in the closed circuit.
Speed Sensor Inspection: For models equipped with speed sensors, regularly inspect the sensor and its connections to ensure accurate and reliable speed signals.
Regular Inspection Schedule: Regular inspection of the hydraulic system and axial piston unit is recommended. Check hydraulic fluid level daily and monitor operating temperature, noise levels, and case drain flow regularly. Abnormal increases may indicate internal wear or seal degradation.
