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.

|---|---|
| Product Name | Forged Cylinder Ends for High-Pressure Hydraulic Cylinders |
| Material Grades | - 42CrMo4, 35CrMo, or equivalent alloy steels – optimized for high-pressure, heavy-duty hydraulic service, with excellent toughness, fatigue resistance, and dimensional stability |
| Forging Equipment | - Hydraulic Hammers & Presses: 5T / 8T / 12T – Suitable for forging precise cylinder ends with uniform directional grain flow and minimal internal defects |
| Manufacturing Process | Material Verification → Controlled Heating → Open Die Forging → Quenching & Tempering (Q+T) → Rough Machining → Non-Destructive Testing → Dimensional Inspection → Protective Packaging |
| Forging Ratio | ≥ 3.0 – Guarantees fiber orientation, reduces internal flaws, and enhances resistance to cyclic pressure and high-impact loads |
| Applications | - High-pressure hydraulic cylinder heads and end caps - Cylinders for construction machinery, mining equipment, and port lifting systems - Heavy-duty hydraulic actuators and piston sleeve assemblies |
| Delivery Conditions | - Standard: Quenched and Tempered (Q+T) - Optional: Normalized + Tempered, semi-machined, or as-forged to meet specific assembly or sealing requirements |
| Testing & Inspection | - Chemical Analysis: Optical Emission Spectrometry - Mechanical Properties: Tensile strength, hardness, and impact testing - Non-Destructive Testing: Ultrasonic Testing (UT), Magnetic Particle Testing (MT) - Dimensional Verification: Full inspection of bore, sealing surfaces, thread accuracy, and roundness |
The steel forgings production flow:
Steel ingot inspection → Cutting → Controlled heating → Forging → Post-forge heat treatment → Blank inspection → Rough machining → NDT & dimensional checks → Quenching & tempering → Final inspection → Finish machining → Dimension verification → Marking & packaging → Warehouse → Shipment
Frequently Asked Questions (FAQs)
1. What is the range of forging weights you produce?
We fabricate forged components from 100 kg up to 7,000 kg, accommodating both medium-duty and large industrial applications.
2. Are heat treatment and machining services available?
Absolutely. All heat treatment processes are performed in-house, and we can supply parts either in rough-machined form or fully finished per customer requirements.
3. Which industries utilize your forged products?
Our forgings are used across wind energy, heavy machinery, port and cargo handling equipment, as well as industrial power transmission systems.
4. How long does production usually take?
For items with material in stock: roughly 30 days
For custom or non-stocked parts: generally 40–45 days, depending on size, material, and machining requirements
5. Where is your manufacturing plant located?
We operate from Changzhou City, Jiangsu Province, near Shanghai, with exports conveniently shipped via Shanghai Port.
