Whether you’re an engineer, technician, or procurement specialist, having a clear grasp of
Rexroth A6VM dimensions can make all the difference in your project planning and
execution. This article delves into the key size specifications, mounting options, and
practical tips for working with these components, along with insights into their design
features.
Understanding Rexroth A6VM Hydraulic Pump Dimensions
The Rexroth A6VM series comprises variable axial piston pumps designed for medium to
high-pressure hydraulic systems. Given the variety of configurations available within the
range, dimensions can vary depending on the pump’s displacement, shaft design, and
mounting options.
Key Dimensional Parameters
When referring to Rexroth A6VM dimensions, several measurements are essential for
proper integration:
Overall Length: This is typically measured from the pump’s mounting flange to the
1.
end of the drive shaft or the rear housing, depending on the configuration.
Mounting Flange Dimensions: The flange size and bolt circle diameter determine
2.
how the pump mounts to the machine or motor adapter.
Shaft Diameter and Length: The drive shaft size is crucial for coupling
3.
compatibility and torque transmission.
Port Locations and Sizes: The inlet and outlet ports’ dimensions and positions
4.
affect hose or pipe connections.
These parameters are standardized to some extent but can vary slightly between different
displacement options within the A6VM series.
Typical Dimensions for Common Models
For example, a widely used model like the A6VM107 typically features:
Length: Approximately 230 to 250 mm
1.
Flange Size: SAE B mounting flange with a bolt circle diameter of around 125 mm
2.
Shaft Diameter: Usually around 25 mm with a keyed or splined design
3.
Port Thread Sizes: Usually G 3/4 or 3/4" BSP for pressure and suction ports
4.
It’s important to consult the specific Rexroth catalog or technical datasheet for precise
measurements, especially if your application requires tight tolerances.
Why Rexroth A6VM Dimensions Matter in Hydraulic System
Design
In hydraulic system design, space constraints and mechanical compatibility are major
considerations. Rexroth A6VM pumps are often integrated into complex machinery such
as construction equipment, industrial presses, and mobile hydraulic systems. Knowing the
exact dimensions helps in several ways:
Ensuring Proper Fit and Alignment
Installing a pump that doesn’t fit correctly can cause misalignments, leading to premature
wear and potential failure. The mounting flange and shaft dimensions must match the
coupling and housing precisely. For instance, using an A6VM pump with a non-standard
shaft length could result in improper coupling engagement, risking shaft damage.
Facilitating Maintenance and Replacement
Hydraulic pumps need periodic servicing. If the replacement pump matches the Rexroth
A6VM dimensions of the original unit, technicians can perform swaps quickly without
modifying mounting brackets or piping. This reduces downtime and maintenance costs.
Optimizing Hydraulic Performance
Port sizes and locations directly impact flow efficiency and pressure losses in a hydraulic
circuit. Pumps with appropriately sized ports and well-planned dimensional layouts
contribute to better system performance and lower energy consumption.
Installation and Mounting Considerations for Rexroth A6VM
Pumps
Mounting Flanges and Bolt Patterns
Rexroth A6VM pumps typically use standardized SAE mounting flanges, such as SAE B or
SAE C. These flanges come with defined bolt circle diameters and bolt sizes, ensuring
interchangeability across different manufacturers and equipment.
When planning installation, verify:
The flange type matches your system’s mounting bracket.
1.
The bolt circle diameter aligns correctly.
2.
The bolt sizes and lengths are adequate to secure the pump firmly without
3.
distortion.
Shaft Coupling and Alignment
The pump’s drive shaft must connect seamlessly with the prime mover, whether an
electric motor or an engine. Rexroth offers various shaft end designs including keyed
shafts, splined shafts, and tapered shafts.
Proper shaft alignment is paramount to avoid vibration and excessive wear. Always
measure the actual shaft diameter and length and compare with the coupling dimensions.
Using flexible couplings can sometimes compensate for minor misalignments.
Port Connections and Hydraulic Lines
Rexroth A6VM pumps have standardized inlet and outlet ports, but the exact thread types
and sizes may differ depending on the model and displacement. Common port standards
include BSP and SAE threads.
Make sure hydraulic hoses or pipes fit these ports securely, and avoid excessive bending
or stress on the lines, which could affect sealing and longevity.
Accessing Rexroth A6VM Dimension Data and Technical
Documentation
For engineers and technicians, having access to detailed technical documents is
invaluable. Bosch Rexroth provides comprehensive datasheets, CAD drawings, and
installation manuals for the A6VM series. These documents include:
Detailed dimensional drawings with all critical measurements labeled
1.
Mounting and installation instructions
2.
Performance curves and operational limits
3.

4.
Many of these resources are available on the official Bosch Rexroth website or through
authorized distributors. Utilizing these resources ensures that your choice of Rexroth
A6VM pump fits perfectly within your hydraulic system’s design parameters.
Tips for Working with Rexroth A6VM Dimensions in Your Projects
1. Always Double-Check Compatibility
Before purchasing or installing, verify that the pump’s dimensions align with your existing
system components. Even minor deviations can cause installation headaches.
2. Use CAD Models for Precise Planning
If your project involves custom machinery, integrating Rexroth’s 3D CAD models of the
A6VM pumps into your design software allows for precise spatial planning and helps avoid
unexpected clashes.
3. Consider Environmental Space Constraints
Take into account not only the pump’s physical size but also the clearance needed for
maintenance access, cooling, and vibration isolation.
4. Consult with Rexroth Experts
When in doubt, reach out to Bosch Rexroth’s technical support to clarify dimension details
or to get recommendations tailored to your application.
Exploring Variants Within the A6VM Series and Their Dimensional
Differences
The A6VM series includes pumps with a variety of displacements, from around 20 cc/rev
to over 200 cc/rev. These variations result in changes in overall size and weight.
Higher displacement pumps tend to be larger and heavier due to increased piston size
and housing requirements. This impacts mounting flange dimensions, shaft specifications,
and port sizes.
Understanding these dimensional differences helps when upgrading or replacing pumps,
ensuring the new unit fits without requiring costly modifications.
Impact of Rexroth A6VM Dimensions on Hydraulic System
Efficiency
While dimensions primarily influence mechanical fit and installation, they indirectly affect
system efficiency. For example, a pump with larger port sizes and optimized internal
geometry reduces pressure drops, improving volumetric efficiency.
Moreover, correctly sized pumps reduce energy losses and heat generation, extending
system life and reducing operating costs.
In summary, having a thorough understanding of Rexroth A6VM dimensions is pivotal for
anyone working with hydraulic axial piston pumps. From ensuring precise mechanical
integration to optimizing system performance, these measurements play a foundational
role in successful hydraulic system design and maintenance. By leveraging technical
resources and paying attention to critical dimensional parameters, you can maximize the
benefits of Bosch Rexroth’s reliable A6VM pump series across a wide range of industrial
applications.
