A hydraulic cylinder is a mechanical device that generates force in one direction. It magnifies linear force using fluid (hydrostatic energy). A tiny force applied to a small region is transferred and amplified into a huge force applied to a broad area.
The hydraulic cylinder can make the action includes, lifting, pulling, pushing, holding, and bending through the linear force. They’re useful in a variety of industries, including aerospace, industrial, defense, and material handling.
WEITAI offers a vast selection of hydraulic cylinders, with a long-term focus on the North American market. Choosing the proper machine to buy can be difficult if you’re trying to buy. Depending on your demands, there are hundreds of alternatives and adaptations. This article goes through it in depth.

1. CAPACITY

Hydraulic cylinder’s force is determined by its internal pressure and surface area.

To have the correct size, you’ll have to work backward to figure out how much force, speed, and capability you’ll need. When it is subjected to a load greater than its capability, the eye bearing might be damaged, resulting in equipment failure. Medium-duty cylinders, with a force/pressure of roughly 1000 PSI, are used in the majority of industrial applications. Heavy-duty cylinders capable of exerting up to 3000PSI are required by hydraulic presses and the automobile industry.

2. SPEED

The speed of your machine is determined by the amount of speed you acquire from your system. Depending on your application, though, your notion of speed will be different.

Standard cylinder seals are capable of handling speeds of up to 1 meter per second (3.28 feet per second). Standard loads can only travel at a speed of 23 meters per second (2.19 feet per second). If you need a higher speed, you’ll need low-friction seals in your hydraulic cylinder. However, keep in mind that what you gain in performance may be offset by a loss in another area. Higher speeds, for example, imply higher fluid velocity and, as a result, higher temperatures. To avoid overheating and malfunction, you must account for the rising temperature throughout the hydraulic system.

3. TEMPERATURE

Hydraulic systems may function in temperatures ranging from 65°F (-54°C) to 500°F (260°C) without any modifications.
Consider how system temperature affects hydraulic cylinders’ ‘hard’, and ‘soft’ components over time.

As a result, applications that require severe temperatures should take into account these impacts and strike the correct balance in order to achieve long-term performance. Expect intense cold to cause seals and metal pieces to compress around the poles, for example.

4. MOUNTING

The proper operation of a hydraulic system is dependent on the interaction of various components.

You can avoid malfunctions by constantly considering the impact of each component on the overall system. Such problems are usually the result of ordering components separately rather than the entire system at once. To ensure proper operation, you’ll need to check the mounting distance, including the retract distance and extending distance.

 5. CYLINDER TYPES

Normally, the hydraulic cylinders are divided into single and double-acting hydraulic cylinders based on the acting directions. Single-acting cylinders exert force on only one side of the piston, causing the piston rod to move in only one direction. 
When operating a crankshaft, double-acting cylinders can exert pressure on both sides of the piston alternately. 

6. DESIGN

The type of design you require, like all other criteria, is determined by your application. Today, there are three primary designs to choose from:

• Tie Rod Cylinder

A cylinder barrel is enclosed on all sides by strong steel rods with two caps on each end. Steel rods are required in larger cylinders that can sustain higher pressure. Smaller units may only have four rods, whereas larger ones may have up to twenty. They are mostly employed in industrial settings. In comparison to welded cylinders, the tie rods are easy to remove, making maintenance easier.

For WEITAI Stand series for Tie Rod cylinder, is divided into WTR2.5 series and WTR3.0 series, with the operating pressure 2500PSI and 3000PSI. The bore diameter is from 2.00″ to 5.00″ and the stock is from 4.00″ to 72.00″.

• Welded Cylinder

There are no tie rods on them; instead, the caps are soldered to the cylinder barrel directly. They are thus stronger and thinner than tie rod cylinders. They can easily be reduced in size for use in smaller machines and engines. Excavators, bulldozers, and cranes are all examples of vehicles that use welded cylinders.

For WEITAI Stand series for Welded cylinder, is divided into cross tube cylinders, clevis end cylinder, pin through cylinders, and adjustable clevis end cylinder based on different mounting styles. The bore diameter is from 1.50″ to 5.00″ and the stock is from 4.00″ to 72.00″.

• Plow Cylinder

The plow cylinder is for the snowplow and snowplow.

For WEITAI standard product is the SP Series, which is specialized in the fabrication of hydraulic cylinders for snowplows and snow equipment. We have ram-type cylinders in sizes ranging from 1 3/4′′ to 2 1/4′′ in our basic line.

• Telescopic Cylinder

Telescopic cylinders are a type of telescoping cylinder. Telescopic cylinders are made up of many concentric welded barrels that can be retracted. They’re designed this way to allow for a long reach.

For WEITAI standard series for the Telescopic cylinder, is divided into 7 Tons and 12 Tons based on the load capacity.

7. VALUE

The price is deliberately placed last as a factor because you must choose based on your needs before looking at the price tag.

Single-action cylinders are less expensive than double-action cylinders.

Larger cylinders will cost more than smaller cylinders.

Customizations will also incur additional costs, depending on the extent of customization. Specialist or robust/reinforced cylinders, such as those designed to work in harsh environments, will be expensive.

You should also expect to pay more if you require customizations to be delivered quickly. Larger batch orders are less expensive because input costs per unit are reduced when producing more units.

Choose a reputable company with rich experience in hydraulic cylinder manufacture that can handle both small and large batch orders. 

SUMMARY

Working with experienced and reputable manufacturers is the most important tip when purchasing hydraulic cylinders. Knowledgeable sales technicians will also assist you in selecting the correct cylinder and will recommend customizations to improve efficiency and performance.

Do not be afraid to spend more money upfront for a cylinder that is specifically designed to meet your needs. Higher-quality, custom-made machinery will serve you better and provide benefits in terms of efficiency and lifespan.

Finally, keep up with the necessary repairs and maintenance. Working with a minor flaw can cause long-term damage to the entire system.
