Model 90R045 / 90L045 / 90R055 / 90L055 is a bearingless variable axial piston hydraulic pump belonging to the Danfoss 90R90L Series, with customizable internal production coding for different specification variants. Adopting the 90 Series proprietary swash plate piston displacement technology and robust cylinder block-valve plate friction pairing design, this pump works as a direct aftermarket replacement for original OEM Danfoss pump parts of the same 90R045,90L045,90R055,90L055 specifications.

The 90R90L Series covers premium high-efficiency piston pumps inside Danfoss' hydraulic pump lineup, delivering stable high flow and high-pressure output within a compact casing size. Under severe service environments including forestry operations, open-pit mining and civil construction projects, these pumps feature outstanding pressure resistance and long-term operational durability, acting as the preferred core hydraulic power source for heavy-duty machinery such as mobile crushing stations, large-sized combine harvesters and main hydraulic systems of skid steer loaders. Designed with standard SAE heavy-duty mounting standards and multi-bolt fixed flange layout, the whole series can endure frequent heavy shock loads and continuous mechanical vibration.

This pump range supports a bearingless structural option, a special customized variant of the 90R90L Series purpose-built to pair with customer-assembled planetary gear reducers and integrated hydraulic transmission assemblies. This bearingless version eliminates the conventional independent output shaft, and directly engages with matched gear set of peripheral drive systems through custom spline sleeves and dedicated tooth profiles. It is ideal for hydraulic systems restricted by narrow installation space or mechanical equipment adopting integrated modular and lightweight design concepts.

1. Bearingless Design - An Ideal Choice for Integrated Drive

90R90L Series Danfoss Pump Hydraulic Piston Pump 90R045 90L045 90R055 90L055 is a bearingless configuration variant in the 90R90L Series:

No separate output shaft: No conventional output shaft is adopted, and external radial loads are borne by the bearing system inside the user's equipment; Direct integration with planetary gearboxes: The pump can be directly mounted to specific hubs or reducer input ends without additional support bearings or couplings; Minimum axial length: The bearingless design greatly reduces the overall length of the pump, making it especially suitable for installation environments with extremely limited axial space; Easy installation: Standard pilot dimension and multi-bolt fixed flange layout, enabling simple matching with user-side equipment and excellent concentricity.

2. 90R90L Series - Highest Performance Axial Piston Hydraulic Pump

The Danfoss 90R90L Series represents the highest-performance axial piston hydraulic pumps in the brand's product line:

High power output: Delivers ultra-high power density within a compact footprint; Advanced swash plate & cylinder block assembly: Adopting optimized rolling friction matching design, it features significantly higher mechanical efficiency than conventional piston pump structures; Precision valve plate flow distribution technology: Provides automatic wear compensation, maintains high volumetric efficiency over the long term, and minimizes pressure loss; Harsh condition adaptability: Capable of withstanding severe operating conditions such as high pressure, low-viscosity oil, and frequent variable displacement adjustment.
