Honed tubes are the materials of the core components of hydraulic cylinders and telescopic cylinders. The quality of the honed tube directly affects the operation of the cylinder. Golbal HydraulicSteelTube focuses on the research and development of high-precision seamless honed tubes. Provide reliable hydraulic solutions for the industrial field.
Our honed tubes are made of high-quality carbon steel or alloy steel. After precision machining, the inner wall surface roughness is controlled within the range of Ra0.2-0.4μm, and the straightness error does not exceed 0.1mm/m. This precision can reduce the running resistance of the piston bar. Improve the working efficiency of the hydraulic cylinder.
What is Honed Tubes?
Honed tube is a precision machined steel tube. It is mainly used in the manufacture of hydraulic cylinders or telescopic cylinder barrels. The inner wall roughness of the tube is controlled to the micron level through a unique honing process. This ensures the accuracy of the inner diameter (ID) size of the bunished tube.
The honing process can form a uniform oil storage structure and ensure the smoothness of the piston movement. It’s can reduce the friction between the piston rod and the inner wall components of cylinder. Increase 14-21% mechanical efficiency of hydraulic cylinder
Why Honed Tubing is Crucial for Hydraulic Cylinders?
Honing process can control the internal roughness of hydraulic honed tube to Ra=0.2-0.4μm. Tolerance standard of the inner diameter of the tube can comply with ISO H7, ISO H8, ISO H9. High precision ensures stable operation between the piston rod and the cylinder. This improves the working efficiency of the hydraulic cylinder. It also enhances the fatigue resistance of the cylinder and reduces the risk of leakage.
Manufacturing Process of Pre Honed Steel Tubing
Honed tubeing are produced with an innovative production process system and strict standards. Ensure that they meet strict quality standards. Unlike welded tubes, seamless steel tubes have advantages in mechanical properties and reliability due to their seamless structure.
Three key links:
Cold Drawing Process: Through multiple passes of diameter reduction and stretching, the outer diameter size (tolerance ±0.05mm) and wall thickness uniformity (deviation ≤5%) are accurately controlled under the support of the mandrel
Honing Process: Use high-precision CNC honing equipment, combined with diamond grinding tools, to control the inner surface roughness within the range of Ra0.2-0.4μm.
Precision Measurement: 100% full inspection of the inner diameter size of the tube to ensure that they meet specific requirements.
The seamless structure of honed bunished tube gives it excellent pressure-bearing performance. It is suitable for high-pressure hydraulic systems above 35MPa. For example: heavy-duty fields such as engineering machinery and ship hydraulics.
Why Choose Seamless Honed Tubes for Hydraulic Applications?
Based on the technical advantages of seamless honing tubes, it is widely used in the field of hydraulic system design and manufacturing.
Structural integrity: The seamless structure adopts the overall cold drawing forming process to avoid the heat affected zone and weld stress concentration problems existing in welded tubes.
Accurate size: Through the honing process, the inner diameter (ID) tolerance can be controlled at ±0.01mm and the outer diameter (OD) tolerance can be controlled at ±0.05mm. The internal leakage rate is reduced.
Surface roughness: Bunished honing tubes reduce the friction coefficient of the inner wall and increase the service life of the piston rod moving parts.

Understanding ID and OD Measurements in Cylinder Tubes
Accurate ID and OD measurements are critical to the manufacture of cylinder tubes. OD determines the integrity of the tube, ID determines the internal dimensions after honing:
ID dimension affects the quality of the piston and cylinder fit. Controlling the ID tolerance within ±0.01mm reduces the piston rod movement resistance by 30-40%, and the internal leakage is <0.1mL/min.
OD accuracy affects the assembly quality of the cylinder and the end cover. Controlling the OD tolerance within ±0.05mm makes the assembly stress distribution uniform.
We provide a variety of tube diameters to meet various specifications. Make it compatible with different hydraulic cylinder designs.
The Role of Chrome Plated Rods in Hydraulic Cylinders
chrome plated piston rod is a key moving part in the hydraulic cylinder. It’s performance affects the reliability of the entire system.
Chrome plating process: Through the hard chrome plating process, a chrome layer with a thickness of 0.03-0.05mm is formed on the surface of the bar. The hardness of the chrome layer reaches HV800-1000. Thereby improving corrosion resistance and resisting chemical erosion of hydraulic oil.
Friction optimization: Precision grinding and superfinishing process, control surface roughness Ra=0.1-0.2μm. Reduce wear rate.
The composite process of induction quenching + chrome plating is adopted. The surface hardness of coating is: HRC65-75, fatigue strength is: ≥500MPa
How Honing Ensures Precision
In the manufacturing process of hydraulic cylinders, honing technology is the core technology for achieving precision machining.
Abrasive honing: CNC honing equipment is used with diamond grinding tools to control the inner surface roughness through multi-stage honing process. Thereby eliminating microscopic defects and forming a 120° cross-net structure.
Inner diameter size control: A high-precision online measurement system is used to monitor the inner diameter size in real time.
Quality assurance: Each tubes is 100% endoscopically inspected, mechanical properties tested, dimensionally inspected, and pressure tested. Ensure that the product qualification rate reaches more than 99.9%.
