FESTO stroke cylinder in stock DSNU-25-160-PPV-A

In fact, a single rod cylinder is a general term and does not have a formal name. My understanding is that it is a type of cylinder where a rod extends. This type of cylinder includes thin cylinder, pencil cylinder, standard cylinder, etc. Although the names are different, the principle is the same: it is simply a structure of gas pushing a piston rod. This type of cylinder has several advantages: cheap price, simple structure, flexible use, diverse forms, etc. But personally, I feel that there are also some shortcomings in using it: the guiding performance is not very good, after all, it is a single axis structure. Especially for long stroke single rod cylinders, the position deviation is still relatively large when the shaft extends to the limit. This should deeply resonate with friends who have used it, as it is due to the structure of the cylinder itself. So this type of cylinder is not suitable for high-precision working conditions. Of course, there is also a solution, which is to use an external guiding mechanism, such as designing a guide rail or sleeve to connect with it, to improve accuracy.

Adjustable booster cylinder is a sublimation version of pre pressure booster cylinder. It is controlled by an adjustable axis on the outside to control the stroke length. The customer sets the maximum preloading stroke and then freely adjusts the length of the stroke according to the actual needs of different products. The product is equipped with two adjustable nuts, which are easy to operate, stable, and fast. The product design is agile, the structure is reasonable, the operation and maintenance are simple, precise, and accurate. It can be used for stamping, marking, bending, punching, cutting, impact welding, extrusion, straightening, riveting, forging, shaping, assembly, connection, stamping, extrusion, bending, forming, trimming and other occasions that require stroke control of the booster cylinder. Sentuo brand specializes in the research and development, production of gas-liquid booster cylinders, electric cylinders, superchargers, and boosting equipment.

Characteristics of adjustable boost stroke gas-liquid boost cylinder;

a: Flexible control of boost stroke according to the needs of different products, precise and accurate

b: Easy adjustment and affordable price.

Advantages of adjustable boost stroke gas-liquid boost cylinder:

a: Beautiful body shape: The product design is innovative and the appearance is beautiful;

b: Fast speed: The action speed is faster than hydraulic pressure and more stable than air pressure;

c: High output: capable of reaching the high output of hydraulic systems;

d: Easy to control: Can achieve manual foot pedal and fully automatic control:

e: Easy to install: Multiple installation methods can be provided for different occasions;

f: Easy to maintain: The cylinder structure is simple and lightweight, and easy to transport, making maintenance quite simple;

g: Low energy consumption: When the mechanical continues to pressurize or stop moving, the hydraulic system motor still needs to run. Compared with this, the power source of the booster cylinder is convenient, and the actual energy consumption is equivalent to 10% -30% of the hydraulic system;

h: Less faults: No disturbance caused by temperature rise in the oil pressure system.

i: High material quality: All seals of the product are made of imported components (Parker seals from the United States and NOK seals from Japan) to ensure that our products can achieve characteristics such as long service life, high precision, large output, small size, and zero leakage.

The inner diameter of the FESTO cylinder barrel represents the magnitude of the cylinder output force. The piston should slide smoothly back and forth inside the cylinder, and the surface roughness of the cylinder should reach Ra0.8um. For steel pipe cylinders, the inner surface should also be plated with hard chromium to reduce frictional resistance and wear, and to prevent rusting. In addition to using high carbon steel pipes, the cylinder barrel material is also made of high-strength aluminum alloy and brass. Small cylinders use stainless steel pipes. Cylinders with magnetic switches or cylinders used in corrosion-resistant environments should use materials such as stainless steel, aluminum alloy, or brass for the cylinder barrel. FESTO cylinder piston adopts a combination sealing ring to achieve bidirectional sealing, and the piston and piston rod are connected by rivets without nuts. FESTO cylinder end caps are equipped with intake and exhaust ports, and some also have buffer mechanisms inside the end caps. The end cover on the rod side is equipped with a sealing ring and a dust ring to prevent air leakage from the piston rod and prevent external dust from entering the cylinder. A guide sleeve is installed on the end cover of the rod to improve the guiding accuracy of the cylinder, withstand a small amount of lateral load on the piston rod, reduce the downward bending of the piston rod when it extends, and extend the service life of the cylinder. The guide sleeve usually uses sintered oil containing alloy and forward leaning copper castings. In the past, malleable cast iron was commonly used for end caps, but now in order to reduce weight and prevent rust, aluminum alloy die-casting is often used, and brass material is used for micro cylinders. FESTO cylinder piston is a pressurized component in the cylinder. To prevent air leakage between the left and right chambers of the piston, a piston sealing ring is installed. The wear-resistant ring on the piston can improve the guidance of the cylinder, reduce the wear of the piston sealing ring, and reduce frictional resistance. Wear resistant rings are made of materials such as polyurethane, polytetrafluoroethylene, and synthetic resin for fabric clamping. The width of the piston is determined by the size of the sealing ring and the necessary length of the sliding part. The sliding part is too short, which can easily cause early wear and jamming. The materials commonly used for pistons are aluminum alloy and cast iron, while pistons for small cylinders are made of brass. The FESTO cylinder piston rod is the most important load-bearing component in the cylinder. High carbon steel is usually used, with a surface treated with hard chrome plating, or stainless steel is used to prevent corrosion and improve the wear resistance of the sealing ring. FESTO cylinder seals: The sealing of components in rotary or reciprocating motion is called dynamic sealing, while the sealing of stationary parts is called static sealing.
