Custom Hydraulic Cylinder Tubes & Honed Tubes: 20# - 316 Materials, Comprehensive Non-Standard Solutions

Product Description

Hydraulic Cylinder Tube - Premium Quality and High - Performance
 
Our hydraulic cylinder tubes are engineered to meet the most demanding industrial requirements.
 
1. Material Excellence
Crafted from high - grade materials such as 20#, 45#, 27SiMn, 40Cr, 42CrMo, 304, and 316. These materials endow the tubes with excellent mechanical properties, including high strength, good wear - resistance, and corrosion - resistance. For instance, the 42CrMo material offers outstanding strength and toughness, making it ideal for high - pressure applications, while 304 and 316 stainless steel variants are highly resistant to corrosion, suitable for harsh environments.
 
2. Precision Manufacturing
Utilizing advanced manufacturing techniques, especially honing processes. The honing technology ensures an extremely smooth inner surface of the cylinder tube. This not only reduces friction between the piston and the tube wall, enhancing the efficiency of the hydraulic system, but also extends the service life of the cylinder. The dimensional accuracy is strictly controlled, ensuring seamless integration with other hydraulic components.
 
3. Customization Capability
We offer customization services to meet non - standard requirements. Whether it's special dimensions, unique material combinations, or specific surface treatments, our experienced engineering team can work closely with you to develop tailored solutions. This flexibility makes our hydraulic cylinder tubes suitable for a wide range of applications, from heavy - duty industrial machinery to precise automation equipment.
 
4. Versatile Applications
Widely applied in various industries, such as construction machinery (e.g., excavators, bulldozers), lifting equipment, and automotive manufacturing. In construction machinery, our cylinder tubes can withstand the rigorous working conditions, providing stable and reliable power transmission. In the automotive industry, they contribute to the precise operation of hydraulic systems in vehicle manufacturing processes.

 

 

Product Parameters of Hydraulic Cylinder Tubes
 
1. Material - related Parameters
 
- Material Grades: Available in 20#, 45#, 27SiMn, 40Cr, 42CrMo, 304 (Stainless Steel), 316 (Stainless Steel).
 
- Mechanical Properties
 
- Tensile Strength: Varies depending on the material. For example, 45# steel typically has a tensile strength of around 600 MPa; 42CrMo steel shows a higher tensile strength, usually above 1000 MPa, ensuring high - load - bearing capacity.
 
- Yield Strength: 20# steel has a yield strength of approximately 245 MPa, while 27SiMn steel has a yield strength of about 355 MPa, which is crucial for the tube's ability to resist plastic deformation under stress.
 
- Hardness: Measured by different hardness scales. For instance, 40Cr steel after heat treatment may have a hardness of around HRC 28 - 32, affecting its wear - resistance.
 
2. Dimensional Parameters
 
- Outer Diameter: Ranges from [minimum value] mm to [maximum value] mm, with a tolerance of ±[tolerance value] mm, ensuring compatibility with various hydraulic system designs.
 
- Inner Diameter: Precision - controlled within a tolerance of ±[tolerance value] mm, which is vital for the smooth movement of the piston. Common inner diameter ranges from [minimum value] mm to [maximum value] mm.
 
- Wall Thickness: Typically from [minimum value] mm to [maximum value] mm, and can be customized according to specific pressure - bearing requirements.
 
- Length: Standard lengths range from [minimum value] mm to [maximum value] mm. Custom lengths are also available to meet non - standard installation needs.
 
3. Surface Treatment - related Parameters
 
- Surface Roughness: After honing treatment, the inner surface roughness (Ra value) can reach as low as [value] μm, which effectively reduces friction and improves the service life of seals.
 
- Corrosion Resistance Level: For stainless - steel materials like 304 and 316, they can pass specific corrosion resistance tests, such as the [test name] test, with a corrosion rate not exceeding [value] g/(m²·h). For carbon steel materials, after appropriate surface treatments (e.g., plating, painting), they also show good corrosion - resistance performance.
 
4. Pressure - related Parameters
 
- Working Pressure: Different materials and wall thicknesses determine different working pressures. Generally, tubes made of 20# and 45# steel can withstand working pressures from [minimum value] MPa to [maximum value] MPa. High - strength materials like 42CrMo can withstand much higher working pressures, up to [value] MPa or more, suitable for high - pressure hydraulic systems.
 
- Burst Pressure: Significantly higher than the working pressure, providing a safety margin. For example, a tube with a working pressure of 20 MPa may have a burst pressure of over 60 MPa, ensuring system safety under extreme conditions.
