Ano ang Honing? Proseso, Mga Tool at Karaniwang Resulta Ang isang hydraulic cylinder tube ay tumatagal ng 12 minuto upang mahasa. Ang parehong tubo na iyon na natapos sa skiving at roller burnishing ay nangangailangan ng wala pang dalawang minuto. Ang 90% na agwat ng oras na iyon ang dahilan kung bakit mas ...
Ano ang DOM Tubing? Ipinaliwanag ang Proseso ng Paggawa Hindi inilalarawan ng DOM ang isang bakal na grado. Ito ay kumakatawan sa Drawn Over Mandrel, isang pangalawang proseso ng cold-finishing na nagpapalit ng electric resistance welded (ERW) tube sa isang produkto na may mas mahigpit na tolerance, mas mat...
Ano ang DOM ST52.3 Tube? Ang isang hydraulic cylinder tube na nagbubunga ng mid-stroke ay nagkakahalaga ng higit sa anumang masusukat na pagkalkula ng downtime ng makina. Tinutulay ng DOM ST52.3 tube ang agwat sa pagitan ng commodity welded tubing at mamahaling seamless na produkto, na naghahatid ng lakas n...
A honed tube for hydraulic cylinder is a precision-engineered seamless or welded steel tube that undergoes an internal surface finishing process known as honing. This process creates a cross-hatched microstructure on the inner bore, which is critical for optimal oil retention and piston seal performance. The resulting surface roughness typically ranges between Ra 0.1–0.4 µm, ensuring minimal friction and wear during reciprocating motion. At Jiangsu Suao Metal Product Co., Ltd., we produce honed tubes with tight dimensional tolerances—often within ±0.05 mm on inner diameter—and straightness under 0.3 mm/m, meeting the demanding requirements of high-pressure hydraulic systems.
SRB (Skived and Roller Burnished) tube is another high-performance option for hydraulic cylinder barrels, offering superior surface finish and mechanical properties compared to conventional honed tubes. The SRB process involves skiving to remove material and then roller burnishing to cold-work the surface, achieving a mirror-like finish with Ra values as low as 0.05 µm. This not only enhances corrosion resistance but also improves fatigue strength due to induced compressive residual stresses. As a manufacturer with integrated cold drawing and finishing lines, we at Suao can deliver SRB tubes in both carbon and alloy steel grades, tailored to operating pressures exceeding 350 bar.
The selection of base material significantly influences the performance of a hydraulic cylinder honed tube. Common grades include ST52 (E355), Ck45, 20MnV6, and 42CrMo4, each chosen based on required tensile strength, weldability, and hardenability. After cold drawing—which enhances dimensional accuracy and surface integrity—the tubes undergo stress-relief annealing to prevent distortion during subsequent machining or honing. We incorporate inline ultrasonic testing and eddy current inspection to detect subsurface defects, ensuring every hydraulic cylinder honed tube we supply meets ISO 8535-1 standards for hydraulic fluid power applications.
Beyond dimensional precision, surface condition plays a decisive role in the longevity and reliability of steel tubes for hydraulic cylinder barrels. To combat corrosion during storage and transport, we offer three primary surface treatments:
As a certified Custom Surface-Treated Steel Pipes – E-Coated, Phosphated, and Oiled manufacturer in China, we tailor these treatments to your logistics environment and assembly timeline.
| Parameter | Honed Tube | SRB Tube |
| Surface Roughness (Ra) | 0.1–0.4 µm | 0.02–0.08 µm |
| Production Lead Time | Moderate | Shorter (single-pass process) |
| Typical Wall Thickness Range | 4–40 mm | 6–30 mm |
| Best Suited For | Heavy-duty cylinders, long stroke applications | High-speed, high-cycle, or cleanroom environments |
Our dual-capability production lines allow us to recommend the optimal solution—whether honed or SRB—based on your specific duty cycle, pressure rating, and environmental exposure. With over 50,000 tons annual output and smart manufacturing integration, Jiangsu Suao ensures consistent quality across both product types.
