Product Core Description
Our Hydraulic and Pneumatic Cylinder Tubes are engineered for high-performance applications requiring extreme precision and durability. Featuring superior high-pressure load capacity, high structural strength, and exceptional sealing performance, these tubes are built to last.
With a focus on wear and corrosion resistance and an ultra-smooth internal finish, our products are the core components for automotive cylinders, construction machinery, and advanced automation systems.
Key Features & Advantages
-
High-Pressure Resistance: Crafted from high-grade seamless steel to withstand extreme hydraulic pressures without deformation.
-
Precision Honed/SRB Finish: The internal surface is processed via honing or Skiving & Roller Burnishing (SRB) to ensure a mirror-like finish, significantly reducing friction and extending seal life.
-
Superior Durability: Excellent wear resistance and corrosion protection, ideal for harsh operating environments in construction and mining.
-
Tight Tolerances: Precision-controlled Inner Diameter (ID) and Wall Thickness (WT) ensure perfect compatibility with piston assemblies.
