Hydraulic RAM Flanged For Crane Piston Double Acting Hydraulic Cylinder
Production description:
These double-acting hydraulic cylinders with rods are advanced devices to harden hardware with a spherical conical pin and electrical stems. These items are economical and versatile, being easy to apply and use in both medium and small power machines. In addition to this, the perfect seal for the gasket ensured by the low coefficient of friction is another major advantage, eliminating the stick slip phenomena, while the working pressure is up to 180bar.
Key features:
1. Provides low mounting height, no alteration of body crossmembers.
2. Made from special high strength steel to reduce overall weight.
3. Heavily chromed and polished cylinder piston rods for longer seal lift.
4. Threaded head, welded cap design
5. High accuracy and precision thanks to integrated guide
6. Patented secured air bleed device to protect against injury
7. Self-adjusting/adjustable end position cushioning

5. Operating pressure
A hydraulic cylinder consists of a piston sliding within a hollow tube, moved by the pressure of a liquid. The piston, or rod is usually machined.
Double-acting models have tapped holes at both ends for the introduction and evacuation of the hydraulic fluid. This allows the piston to apply force in both directions.
Installation method:
The most commonly used mounting options are flange, trunnion, clevis, pin-eye, cross-tube, spherical, and tang. Cylinder mounting is chosen based upon the application’s requirements.
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.

How to choose:
1. Choice will depend on the operating conditions of the unit. It is necessary to determine the precise physical characteristics and geometry of the installation.
2. The bore, or cylinder diameter will determine the amount of force the piston can apply. Rod characteristics, usually standardized, fastening system, damping and stroke are other important factors.
3. Stroke, in particular, is an essential specification, since it defines the distance the piston travels between its initial and its final position.
4. Additional criteria include the use of presence sensors to indicate the position of the piston, the seals, purge and drain valves, type and temperature of the hydraulic fluid.
