HC Standard Hydraulic Cylinder and its Parameters, Design & Assemble features


Last few years ago, pneumatic cylinder is widely used in industry, production and manufacturing lines. However, as the technology advances, a number of equipments need larger working pressure for their different operational environments. There are some hydraulic cylinder manufacturer start research and developed hydraulic cylinders. Hydraulic cylinder also called hydraulic motor working liner. It is the operating elements of mechanical, the push power apply to single directional, which is in limited stroke. Nowadays, hydraulic cylinders are widely used in machine tool, metallurgy, mineral, chemical engineering, marine, hydroelectric power industries.

Hydraulic cylinders working pressure comes from one kind of special oil compression. Each of hydraulic cylinders has a cylinder bore, piston rod, piston, guide pillar, seal rings, and many other parts. The oil come into cylinder through oil nozzle, and piston rod will telescopic movement very well in bore. Another key factor is the seal rings. Therefore, if cylinder piston rod want to connect with piston, hydraulic cylinder supplier should install glide ring and O ring. Piston separates the hydraulic cylinder to two parts- one is cylinder bottom, the other is the end of piston rod. Piston rod move liner when increase oil pressure.
Because of hydraulic cylinder is the supplier of power. Piston rod connects to the machine or other parts all the time. They work together.

Hydraulic cylinder is widely used in many important environments, so find a good supplier that produces best quality products is very important. HC hydraulic cylinder supplier always satisfy customer from 2000. Here I introduce our treating detail of the product- hydraulic cylinder.

Hydraulic Cylinder for a Greater Customer Safety and Satisfaction


The hydraulic cylinder is the same as they were a few years back and the process of manufacturing of the cylinders are just a more sophisticated and advanced. The manufacturing process is more efficient and the basic tolerance of the cylinders is tighter and the cylinders are manufactured very stronger. The cylinders are good for the technical world around us and the things that are pushed and hauled and the dug and crushed, drilled and graded by any of the vehicles like a truck, a crane or the tractor that can haul these cylinders. You can find the cylinders can be a good way to move things.

The rebuilding of the hydraulic cylinders can be the best way to repair the leaking cylinders. The cylinder that has lost the power or is leaking has to be replaced or to be repaired. The need for the repairing of the cylinders is important and the easiest way is to repacking the seals. The hydraulic cylinder maintenance therefore becomes necessary as the cylinder that leaks become unusable. The sealing is simple to perform but still it needs some technical knowledge and repair the cylinder the first time. The maintenance is necessary and then it can bring the repairing option in the first time.

The disassembly of the machine will be easier if the machine is taken apart after the cylinder is taken off from the machine. The cover of the cylinder is taken off from the shaft side of the cylinder and then the screws and the bolts are also taken apart to loosen the covers. The piston is removed and then the input valves are going to be taken off from the inside. The hydraulic cylinder replacement has to be done for proper inspection of the machine when the cylinder is not working properly and before the replacement you can find out the problem of the cylinder that you will be getting.

The standard hydraulic cylinder that you own should be a good thing but you need to take some precautions for that the risks are not there for such storing. The owners are mostly unaware of the things that they need to take care of to store a cylinder. The best way is to store the cylinder indoors so that the cylinder is not damaged, the area should be clean and dry and the cylinder should be retracted while in store. The wet place is not at all a good idea to store the cylinder. Hence make sure it is a dry place and not at all a hot area.

The design of a customized hydraulic cylinder should meet the requirement of the customer’s regular needs. The technological expertise should be aimed towards that goal. The cylinders that are produced by the companies have got different unique characters that are good for a special end user satisfaction and a total efficiency of the activities that the cylinder is to perform. The quality of the cylinder is enhanced and the customer’s satisfaction in the quality and the craftsmanship is taken care of.

Hydraulic Cylinder Replacement for the Proper Working Condition of Cylinder


The cylinders are very common as the pumps and the motors that are used with such cylinders. The hydraulic components that are used for different purpose are easy to repair and then the other equipment and their repair are easy to perform. The repair of the cylinder is also easy to perform as the personnel can do the repair comfortable. The hydraulic cylinder replacement is the only thing that is left if the repair is not successful. The repair of the cylinder is easy and you need to know the right process to complete it.

The most part of the repair work are done in the site while the cylinder is located in-house and the standard hydraulic cylinder can be a good thing to repair within the premises if the repairing is not too extensive. The cylinder that is too much damaged or the repair shop that does not have much efficient tools will not be able to repair the cylinder. The cost of a cylinder or the availability of a cylinder should be considered before you start to think of repairing. You need to find out the most efficient way to repair without further damaging the cylinder.

There are different types of cylinder and you will find the customized hydraulic cylinder to be as per the recommendation of the clients that buy the different machine parts from you. You need to build the cylinders as per your requirement like the product that can be a mechanical actuator that has got a linear force that is called linear hydraulic motor. The tube is skived and there is burnish in the roller. Sometimes the design is the most reliable for the work that the cylinder should do. They are sometimes done in finished steel too for extended life. The chrome of the body makes it live longer.

There are the industrial hydraulic cylinders that can be used for the commercial purpose in the manufacturing world. The cylinders can be of different types and they are mounted as per the order of the customer and their own business requirement. The pressure can differ from 130 bar to 300 bar and the cylinders are available in tie rod design or of different stroke length and of different mounting styles. You will find the cylinders of 40 mm bore to 400 mm or bigger bore and they are there up to 3000 mm stroke on the request. With about 15 different mounting styles and different pressure and standards, you will find the cylinders to be very effective in the industrial field too.

The cylinders are of two types and they can be double acting or single acting. The double acting hydraulic cylinders have fluid on the base and in the rod sides of the part called piston and the fluid is delivered in both sides in the same force. The gravity or weight of the cylinder causes retraction; the acceleration is controlled by applying hydraulic pressure. The double action cylinders are piston type and the cylinder pushes against the piston to prevent the hydraulic fluid.

Standard Hydraulic Cylinder for the Machinery of the World Over


There are different types of the hydraulic cylinder and most of the ones are the standard cylinders that have got all the features that are good for the market and do not bring in any problem for the customer requirement for the day. The standard hydraulic cylinder is good for the repairing purpose and there are different types of cylinder that are sent for repair so that they can be used and there is no need to buy a new one. The one that can be repaired are mostly in need of seal and this is done within the premises of the workshop. The one that does not work even after the seal is placed cannot be saved for the client and replacement of the cylinder is the only option.

There are cylinders that are prepared as per the specification of the customer and they are the customized hydraulic cylinder that is good for the different types of customers. The customization makes it perfect for the customer and they love to bring in more specifications for you to handle. The customers need these cylinders for different purpose and they do not like to work with a new technician if they find the technician that is working on the cylinders to be good. Moreover the cylinders that are customized should be properly done as per the specification and the customers wait to see this perfection.

The industrial hydraulic cylinders that are designed for the market often has got different specification that is good for different industries. The specification of bent rods are there that is required for the cylinders and they are to be made according to the accurate specification of the industry. The ballooning of the tube is also important and there are different specifications of different tubes for different industries. The bearing area o the cylinder is also important and there should not be any minute difference from the specification of the tubes and bearings and the rod.

There are different types of the hydraulic cylinders and one is the double acting hydraulic cylinders have double acting operations and are mostly fit with two opposite facing piston surfaces that has control over the operation of the force that is exerted by the cylinders for most of the work. The special hydraulic oil is used to enable the cylinder to work in two opposite direction. The hydraulic energy is converted to mechanical energy in this way and gives precision by the piston movement.

Researching and developing ability for hydraulic cylinder design and manufacturing by HC


HC has the very strong hydraulic cylinder researching and developing ability for hydraulic cylinder design and manufacturing, during the past more than 10 years experience and researching on the hydraulic cylinder, HC has established company standard of design, machining process standard pressure formula. Due to the experience in design, machining and quality controlling, HC hydraulic cylinder has met all kinds of hydraulic cylinder and also have met all kinds of blind area of quality. The followings are describing to HC experience and technologies knowledge for hydraulic cylinders' design, manufacturing and developing.

Due to the hydraulic cylinders moving is directly, it is only for pushing or pulling, there should be one bending or curves surface in the barrel or in the piston rod. For this reason, the standard hydraulic cylinder should be used for pushing and pulling only. No bending moments or side loads should be transmitted to the piston rod or the cylinder. For this reason, the ideal connection of the hydraulic cylinder should be a single ring with a special ball bearing. In this way, the hydraulic cylinder can move without any miss-alignment between the actuator and the loaded components during the pulling or pushing.

Hydraulic Cylinder Designs
There are mainly two styles of hydraulic cylinder designs used:
  •  Tie rod type hydraulic cylinders
  •  Welded body type hydraulic cylinders
Tie rod type hydraulic cylinders:
Tie rod style hydraulic cylinders use high strength threaded steel rods to hold the two end caps to the cylinder barrel. This method of construction is most often seen in industrial factory applications. Small bore cylinders usually have 4 tie rods, while large bore cylinders may require as many as 16 or 20 tie rods in order to retain the end caps under the tremendous forces produced. Tie rod style cylinders can be completely disassembled for service and repair.

The National Fluid Power Association (NFPA) has standardized the dimensions of hydraulic tie rod cylinders. This enables cylinders from different manufacturers to interchange within the same mountings.

Welded body type hydraulic cylinders:
Welded body cylinders have no tie rods. The barrel is welded directly to the end caps. The ports are welded to the barrel. The front rod gland is usually threaded into or bolted to the cylinder barrel. This allows the piston rod assembly and the rod seals to be removed for service.

Welded body cylinders have a number of advantages over tie rod style cylinders. Welded cylinders have a narrower body and often a shorter overall length enabling them to fit better into the tight confines of machinery. Welded cylinders do not suffer from failure due to tie rod stretch at high pressures and long strokes. The welded design also lends itself to customization. Special features are easily added to the cylinder body. These may include special ports, custom mounts, valve manifolds, and so on.

The smooth outer body of welded cylinders also enables the design of multi-stage telescopic cylinders.
Welded body hydraulic cylinders dominate the mobile hydraulic equipment market such as construction equipment (excavators, bulldozers, and road graders) and material handling equipment (forklift trucks and lift-gates). They are also used in heavy industry such as cranes, oil rigs, and large off-road vehicles in above-ground mining.

Hydraulic Cylinder Trouble Removal


Hydraulic cylinder suppliers pay attention to maintenance also. Hydraulic cylinder trouble removal and hydro cylinder trouble shooting is an important part. Hydraulic cylinder malfunction can solve problems happened in it.

The action of hydraulic cylinder is insensitive and in blocks. This phenomenon is distinct from hydraulic cylinder crawling. It won’t start working upon receipt of the signal, it always stop for a while and then action, or now acting; now stopping. The reasons of this problems and trouble removal are as follows:

1. Too much air in cylinder.

    Removal methods:

a.       Air discharged through vent valve.
b.       Check whether the air intakes from the seals or not. If yes, change the seals.

2. Hydraulic pump revolves irregularly. Such as big vibration noisy, pressure fluctuation seriously, meet a block when the pump rotation, seizure slightly.

  Removal methods can as per relevant books.

3. When a hydraulic cylinder with cushioning device back-to-back starting, the orifice of single valve is too small and make the less of oil in cushion cavity, or vacuum. So it will appear the piston rod stop or reversal phenomenon due to the cushion plunger piston leaves cylinder gland.

   Removal method: enlarge single valve orifice.

4. Single valve‘s steel balls go after the oil flowing when piston rod works fast, it will block the valve orifice and make irregularly action.

   Removal method: as per relevant content.

5. The internal of rubber strips make the valve orifice blocked and result in irregular action.

Removal method: change rubber.

6. Have some transverse load.

Hydraulic Cylinder Removal and protection


HC hydraulic cylinder supplies hydraulic cylinder system, piston rod. In order to know more about the hydraulic cylinder protection, this article will introduce the hydraulic cylinder removal.

HC hydraulic cylinder is a professional production and sale of hydraulic cylinder enterprise, the product quality is high, the price is reasonable. The following share with you the nozzle of hydraulic cylinder removal:


1. Before remove the hydraulic cylinder, should make hydraulic loop discharging pressure. Otherwise, when hose connector loosens which connected to the hydraulic cylinder, circuits of high pressure oil will out quickly. Hydraulic loop when discharging pressure shall first loosen relief valve of the place such as the hand wheel or pressure regulating screws, make the oil pressure unloading, then cut off power supply, make the hydraulic device stop working.

2. When remove the hydraulic cylinder, should prevent the injury for the piston rod top thread, oil hole thread, the surface of piston rod and the inside of cylinder. In order to avoid the in order to prevent the piston rod and slightness piece bending or deformation, place mat wood application in supporting balanced.

3. Remove should in order. Because all sorts of hydraulic cylinder structure and size is not the same, remove the order also differ slightly. Generally should put off oil cylinder of two cavities, oil, then remove the cylinder head, finally remove the piston and the piston rod. When removing the hydraulic cylinder of cylinder head, in key card for connecting card key or card type ring to use the specialized tools, prohibited the use of flat. For flange cover must use screw top out, don’t allow hammering or hard pry. On the piston and the piston rod is difficult to spare, cannot forced hit, should first find out reason to be removed.

4. Unloading before and after discharge should try to create conditions to prevent the hydraulic cylinder part is the dust and impurities pollution around. Such as, remove should as far as possible when in a clean environment, Remove all the parts with plastic cloth after to cover, don’t use cotton cloth or other work covered with a cloth.

5. After hydraulic cylinder removal, Hydraulic cylinder to carefully examine the disassembly to determine what parts can continue to use, can repair what parts of the reoccupy after, what parts must be replaced.
