The Cold Finished CHINAMFG Rolled Drawn H8 H9 Honed Tube DIN2391 CK45 for hydraulic cylinders is a top-tier component, precision-engineered to meet the rigorous demands of modern hydraulic systems. This tube combines the benefits of cold finishing and precision honing, making it ideal for applications requiring high accuracy, smoothness, and robust mechanical properties. Here, we explore the unique features, benefits, and applications of this highly specialized product.

Optimal Material and Process Selection: Constructed from CK45 steel, known for its high strength, excellent machinability, and superb yield properties, this tube is engineered to withstand high stress and wear. The DIN2391 standard to which it conforms ensures that the tube meets stringent quality and precision metrics. The steel is subjected to a cold finishing process, known as “BKS” (Bright cold drawn +SR), where it is drawn to final size and then undergoes a stress-relief anneal. This process not only enhances the steel’s structural integrity but also improves its surface finish and dimensional accuracy.

Precision Honing for Superior Performance: Honing the tube to H8 or H9 tolerance levels further refines the internal surface, reducing roughness and increasing the precision of the internal diameter. This is crucial for hydraulic cylinders, where smooth movement of the piston is essential to maintain the efficiency and longevity of the system. The honed surface allows for better sealing, reduced friction, and enhanced performance, particularly in dynamic conditions.

High Dimensional Accuracy and Surface Quality: The combination of cold drawing and honing processes provides exceptional dimensional accuracy and surface quality. The H8 tolerance ensures a tight fit with other cylinder components, while H9 offers slightly more clearance for applications where additional lubrication may be necessary. This level of precision is particularly important in high-pressure environments where any misalignment can lead to rapid wear and system failure.

Versatile Industrial Applications: This honed tube is extensively used in the manufacture of hydraulic cylinders, but its reliability and precision also make it suitable for pneumatic cylinders, shock absorbers, and any machinery requiring high-precision fluid power dynamics. Industries such as automotive, aerospace, and manufacturing rely on these components for their critical operations, where failure can lead to costly downtime and safety issues.

Compliance and Reliability: Adhering to the DIN2391 standard, the Cold Finished CHINAMFG Rolled Drawn H8 H9 Honed Tube CK45 guarantees compliance with international mechanical and safety standards. This ensures the product’s reliability and quality, making it a preferred choice for engineers and designers across various sectors.

In conclusion, the Cold Finished CHINAMFG Rolled Drawn H8 H9 Honed Tube DIN2391 CK45 hydraulic cylinder is an exemplary product designed for high-stress applications that require precision and durability.

As 1 of the leading hydraulic cylinder honed tube suppliers, our factory manufactures the honed pipes using our factory’s “Suitable To Hone” Steel Cold Drawn Seamless Tubes (CDS tubes). In order to produce extremely precise ID dimensions and smoothly ID surface, the honing process involves using CHINAMFG polishing stones and CHINAMFG paper to remove small amounts of material.

 

Besides the honing process, we also use the SRB process (skiving and roller burnishing) to produce honed tubing.

Honed tube for hydraulic cylinder is ready to use for producing or repairing hydraulic cylinders without any further ID
processing.
