Description
Product Description
The ASHUN RO Series Welded Hydraulic Cylinders are developed for medium-duty industrial applications. Distinct from traditional threaded designs, this series utilizes a high-strength welding process to join the cylinder barrel and rear cap. This integral construction not only grants the cylinder exceptional structural rigidity but also drastically minimizes the risk of fluid leakage under high-frequency operations, demonstrating outstanding system reliability in automated production lines and general machinery.
Furthermore, its streamlined cylindrical exterior effectively reduces installation blind spots within machinery. Paired with versatile mounting configurations such as threaded and flat-tail types, it integrates flawlessly into diverse compact equipment mechanisms.
Product Features
- Comprehensive Round Specs: Bore sizes ranging from Ø40 to Ø125mm, fully meeting the construction needs of medium-scale automation equipment.
- Leak-Proof Welded Barrel: The high-strength seamless welding between the rear cap and barrel significantly enhances compressive rigidity and eliminates oil leaks.
- Premium Material Options: Cylinder tubes are available in carbon steel and stainless steel to adapt to various harsh or corrosive industrial environments.
- Safety Cushion Mechanism: Features an exclusive anti-drop cushion screw design, ensuring stable actuation and drastically reducing high-frequency impact risks.
