What is a Honed Tube?
A honed tube is a precision seamless steel tube that has been processed by honing to achieve an accurate inner diameter and a smooth surface finish.
It is widely used in hydraulic cylinders, pneumatic cylinders, and other applications that require high dimensional accuracy.
The honing process improves roundness, straightness, and surface roughness, making honed pipes ideal for hydraulic cylinder barrels.
What is the Difference Between a Honed Tube and a Skived & Roller Burnished Tube?
Both honed tubes and skived & roller burnished tubes are designed for hydraulic cylinder applications, but the manufacturing methods differ.
A honed tube is produced by removing a thin layer of material through honing, which creates a very smooth finish.
A skived and roller burnished tube, on the other hand, uses a cutting tool to skive the surface, followed by burnishing rollers that compress the metal to achieve the final finish.
Honed tubes typically offer better surface uniformity, while roller burnished tubes provide increased hardness and wear resistance.
What Materials Are Used for Honed Tubes?
Honed tubes are commonly made from carbon steel, alloy steel, and stainless steel depending on the application.
Seamless steel tubes are most frequently used because they offer higher strength, pressure resistance, and durability.
For special environments, stainless steel honed pipes are preferred due to their corrosion resistance.
What Are the Typical Applications of Honed Tubes?
Honed tubes are primarily used in hydraulic cylinders for construction machinery, mining equipment, and agricultural machines.
They are also applied in pneumatic cylinders, automotive shock absorbers, plastic injection molding machines, and other equipment requiring precision hydraulic cylinder barrels.
In the industrial sector, honed pipes are essential for ensuring efficiency, safety, and reliability.
What Are the Standard Sizes and Tolerances of Honed Tubes?
Honed tubes are available in a wide range of diameters, typically from 40mm to 800mm, with wall thicknesses varying according to application.
The inner diameter tolerance is usually H8–H9, while the surface roughness can reach Ra 0.2–0.4 μm.
These precise tolerances ensure that hydraulic cylinder tubes perform smoothly and extend service life.
How Do You Choose the Right Honed Tube for Hydraulic Cylinders?
What Factors Should Be Considered?
When selecting honed tubes, consider the working pressure, temperature, cylinder stroke, and required service life.
The choice of material—carbon steel, alloy steel, or stainless steel—should also match the working environment.
Additionally, check for compliance with standards such as DIN 2391, EN 10305, or ASTM A519 to ensure high quality.
Why Is Precision Important in Hydraulic Cylinder Tubes?
Precision honed tubes guarantee low friction, minimal leakage, and high performance in hydraulic systems.
Accurate dimensions and excellent surface finish reduce wear on seals and extend the operating life of the cylinder.
What Are the Advantages of Using Honed Tubes?
Honed tubes offer superior surface finish, tight tolerances, and excellent roundness.
They improve sealing performance, reduce maintenance costs, and enhance efficiency in hydraulic and pneumatic systems.
Compared to non-honed pipes, honed hydraulic tubes deliver longer service life and greater reliability under demanding conditions.
