Retractable hydraulic cylinder can get a longer working stroke with multistage sleeve-shaped piston rod hydraulic cylinder, telescopic hydraulic cylinder, also known as multistage hydraulic cylinder. Telescopic hydraulic cylinder is composed of two or more piston hydraulic cylinder set. The piston rod of the previous stage piston cylinder is the cylinder of the latter piston cylinde. In general telescopic cylinders are much more expensive than normal cylinders. Most telescopic cylinders are single acting (push).

Application:
Commonly used in construction machinery and other mobile machinery, such as cranes, dump trucks and other hydraulic systems.

Piston Seals:
A. Low friction, high load piston seals with outboard wear bands are standard. Loaded lip seals and cast iron rings are optional. 
B. The seal is the use of rubber or plastic seal of the elastic ring so that a variety of cross-section ring in the static and dynamic fit between the surface to prevent leakage.
C. Common seal are O-shaped, Y-shaped, V-shaped and so on.
D. It has the advantages of simple structure, easy manufacture, automatic compensation after wear, reliable performance, and can be used between the cylinder and the piston, between the cylinder head and the piston rod, between the piston and the piston rod, between the cylinder tube and the cylinder head.

About piston rod:
High strength damage resistant piston rod provides 100,000 PSI minimum yield material in 1" through 4 1/2" diameters. Larger diameters vary between 50,000 and 75,000 PSI minimum yield material. All rods are case hardened to 50-55 RC and hard chrome plated to provide maximum wear life. Stainless steel is also available. The hard chrome plated of the piston rod according to your requirement.

Quality control:
1. Seiko secret agents, to ensure quality of the piston rod.
2. The product have to go through heat treatment - bore boring - grinding - car processing - black nitriding and many other processes.
3. The company accepted the Valet processing various types and various sizes products, processing and processing more quotes, welcome to consult.

Features:
1. Multistage telescopic long stroke hydraulic cylinder applies to long stroke lifting operation.
2. Surface corrosion treatment, bright color, not east to rust.
3. High strength alloy steel with high grade heat treatment, produced by imported CNC lathe, drilling machine and grinding machine.
4. Import seeling parts, not easy to wear after continuous working.
5. Dust ring reduces contamination, extending cylinder life.
6. Single acting, load return.
7. R2 3/8 coupler and dust cap included on all models.
8. Flat saddle is standard, and tilting saddle is available.
