Product Introduction
The Round Flange at Base Hydraulic Cylinder is specifically designed for axial-load-dominant applications where uniform stress distribution, structural simplicity, and installation stability are the primary requirements.
Featuring a symmetrical circular base flange, this mounting type ensures even force transmission into the machine frame, minimizing localized stress and improving long-term reliability.
By fixing the cylinder at the base end, this design is particularly suitable for standardized industrial equipment and batch-production machinery, where consistent performance and easy replacement are essential.
Why This Cylinder Was Designed
In general industrial and metallurgical equipment, overly complex mounting structures can increase cost, installation difficulty, and maintenance risk without delivering additional value.
The Round Flange at Base configuration was developed to address these practical needs by focusing on:
-
Uniform axial load transfer with minimal flange stress concentration
-
Simple and robust installation structure
-
High suitability for standardized and interchangeable hydraulic systems
This makes it an ideal choice for manufacturers seeking cost-effective reliability rather than extreme high-pressure rigidity.
Structural & Performance Advantages
✔ Uniform Stress Distribution under Axial Load
The circular flange geometry effectively reduces stress concentration, improving fatigue resistance and service life.
✔ Simple & Stable Base Mounting
A compact mounting structure simplifies alignment and reduces installation time.
✔ Optimized for Standardized Applications
Well suited for batch production, modular equipment platforms, and standardized machinery designs.
✔ Reliable Long-Term Operation
Designed for stable load directions and continuous industrial operation.
Typical Applications
-
General metallurgical equipment
-
Fixed mounting points in construction machinery
-
Standard industrial hydraulic systems

Selection Tips / Important Notes
-
Round flange at base mounting is designed primarily for axial force transmission.
-
Ensure accurate alignment between the mounting surface and the cylinder axis during installation.
-
Eccentric mounting or poor concentricity may lead to localized flange stress concentration.
-
For applications involving significant side loads or changing force directions, clevis or trunnion mounting is recommended instead.
