Factory Direct Price Excavator Hydraulic Oil Cylinder Replacement

We manufacture a wide range of hydraulic cylinders, including single-acting cylinders, double-acting cylinders, telescopic cylinders, tie-rod cylinders, welded cylinders, and custom-engineered cylinders tailored to specific agricultural, construction, marine, and industrial applications.

Yes, OEM/ODM services are our core strength. We have an experienced R&D team that can design and manufacture exact hydraulic cylinders based on your technical drawings, 3D models (STEP/IGS format), or physical samples.

We use high-quality seamless steel tubes (such as #45 steel or ST52) honed to precise tolerances. Piston rods are made of high-tensile carbon steel, induction-hardened, and finished with hard chrome plating (minimum thickness 20-30 microns) for superior corrosion and wear resistance.

To ensure long-term pressure retention and prevent leaks, we standardly equip our cylinders with premium seal brands such as Hallite, NOK, or Parker. Our multi-stage sealing configuration is designed to withstand high pressures, friction, and extreme temperatures.

Quality is our top priority. Every single hydraulic cylinder undergoes 100% dynamic pressure and static hold testing (up to 1.5 times the rated working pressure) to ensure no internal or external leakage. We also conduct dimensional checks, salt spray testing for rods, and paint thickness checks before packing.
