1. light weight, high strenght
Base on the nature of construction work, the hydraulic cylinders need to suit for high strength, high using frequency, high fatigability. To promise the stability and reliability of application.
2. The seal system
select the excellent seal kits from Japan and Germany. Adopt the advanced physical design, make sure the hydraulic cylinder get the best piston rod oil film.
3. cylinder body
adopt the good quality alloy honed tube, though cold-drawing and rolling, to reach an excellent roughness and surface hardness, improve the wear-resistance.
4. piston rod
middle frequency induction hardening and tempering, chrome plated on rod surface to improve the anti-rust, wear-resistance and anti-scratch property.
5. safety/cushioning function
the inside of cylinder set up an cushioning device in the end of stroke, it can absorb the huge impact.
The welding of piston rod adopts fully automatic welding machine and gas shielded weldin process, while use ultrasonic fault detector to inspect.
The roughness of scrape barreling in the cylinder barrel is up to 0.4.
The parts shall adopt forging skill and be tempered HB ≥250.
Testing pressure is 35Mpa--40Mpa.
