3 4 5stage Telescopic Multistage Hydraulic Cylinder Single Acting Stroke 500mm

Features:
• There are many benefits to using a single acting dump truck cylinder. It's the ideal choice for applications where gravity, weight or other assisting forces are present to move the cylinder in one direction. It could be mounted in any position so that it could be used in a wide range of mobile and industrial applications.
• Every DALLAST single acting telescopic cylinder is individually tested before leaving our plant to assure proper performance and leak-free operation. All cylinder products carry an 12 months warranty.
• Snap on glass filled bearings that absorb contaminants without damaging cylinder walls.
• Nylon tipped set screws that conform to packing nut threads to decrease the probability of packing nuts backing off.
• Single-acting cylinders transfer force and motion in one direction only.
• Higher efficiency: Smaller cylinder diameter makes the smaller working volume, the speed of oil cylinder lifting and falling are more fast and more efficiency, running more can bring more benefits.
• Stronger weather resistance: The application new materials and special structures can adapt to different environment from cold to hot and can round-clock operation.
• Better performance: Imported high quality materials and spare parts make outstanding products performance.

Any model could be customized, Please note that the regularly stocked telescopic cylinders above.

Piston Seals:
Low friction, high load piston seals with outboard wear bands are standard. Loaded lip seals and cast iron rings are optional.
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.
The most common problems when selecting a hydraulic cylinder are as follows:
A. Retract dimension
