Product Introduction
The Rectangular Flange at Head Hydraulic Cylinder is designed for high-pressure, high-load linear motion systems where front-end rigid mounting and precise positioning are critical.
By fixing the cylinder at the head end, this mounting structure provides excellent axial load resistance and enhanced guiding stability, making it ideal for presses, forming machines, and hydraulic stamping equipment operating under demanding conditions.
This design ensures that force is transmitted directly into the machine frame, minimizing deformation and maintaining consistent motion accuracy even at pressures up to 25 MPa.
Why This Cylinder Was Designed
In high-pressure industrial applications, standard mounting methods often struggle with front-end rigidity, alignment accuracy, and long-term stability.
The Rectangular Flange at Head configuration solves these issues by:
-
Strengthening front-end load-bearing capability
-
Improving cylinder guidance under heavy thrust
-
Ensuring stable operation during continuous high-pressure cycles
This makes it a preferred choice for manufacturers seeking precision, durability, and structural reliability.
Structural & Performance Advantages
✔ Strong Front-End Load Capacity
The rectangular head flange provides a rigid mounting interface, capable of withstanding high axial forces without displacement.
✔ Optimized for High Pressure (16–25 MPa)
Designed for standard 16 MPa systems, with reinforced options available for 25 MPa high-pressure applications.
✔ Improved Guiding Stability
Front mounting enhances piston alignment, reducing uneven wear and improving service life in heavy-duty operations.
✔ Industrial-Grade Reliability
Coaxial machining of flange and cylinder body minimizes eccentric loading and structural fatigue.

Selection Tips / Important Notes
-
Rectangular flange at head mounting is best suited for high-pressure, high-load applications with rigid front-end support.
-
Avoid designs where the piston rod is subjected to significant lateral loads.
-
If offset loading or angular motion is unavoidable, clevis or trunnion mounting should be considered instead.
-
For large bore or long stroke cylinders, structural and buckling verification is strongly recommended.
