Forged Cylinder Ends for High-Pressure Hydraulic Cylinders
Forged cylinder ends are specifically engineered for high-pressure hydraulic systems, offering exceptional strength, toughness, and reliability under extreme operating conditions. Manufactured from premium alloy steels such as 42CrMo4 and 35CrMo, each cylinder end undergoes precision forging, heat treatment, and rigorous inspection to ensure optimal mechanical performance and dimensional accuracy.
Key Features:
-
Superior tensile and fatigue strength to withstand high-pressure hydraulic loads.
-
Excellent impact resistance and toughness, reducing the risk of cracking or deformation.
-
Precision forging and machining for accurate thread, bore, and sealing surface dimensions.
-
Heat-treated and stress-relieved for long-term durability and consistent performance.
Applications:
These forged cylinder ends are widely used in high-pressure hydraulic cylinders for construction machinery, mining equipment, heavy industrial presses, and other hydraulic systems requiring reliable load-bearing components. Their robust design ensures safe and efficient operation even under extreme pressure and heavy-duty cycles.
