Piston rod column failure (buckling) can occur if the rod diameter is not sized to match the stroke and load. The manufacturer should be consulted for application assistance.Column strength considerations: Standard size rods are recommended for use in cylinder applications where column strength, rod sag, or rate of...

It’s a sudden, large, and unstable lateral deflection. It can be associated with only a small increase in compressive load above a critical level, known as the buckling load. The corresponding stress can be far less than the yield strength of the rod material.

Hydraulic cylinder drift is caused by internal leaks in the cylinder across the piston. The fluid physically moves from one side of the piston to the other which creates an uneven balance and causes the cylinder to move or “drift”.

Mis-staging is a telescopic cylinder extending or retracting in the wrong sequence. When the cylinder tries to correct its sequence, rapid movement and violent slamming between moving stages can occur.

Generally, no. Speed is a factor of flow. You need more flow to make things move faster.

A telescoping cylinder is a cylinder employing several pistons which telescope into each other. This cylinder is used when a relatively long working stroke is needed for a short cylinder length. Telescopic cylinders are used in a variety of applications that require the use of a long cylinder in a space-constrained...

Telescopic hydraulic cylinders, sometimes called multi-stage cylinders, are a type of linear actuator consisting of a series of tubular rods called sleeves. The sleeves (usually 2 to 6) sequentially decrease in diameter and are nested inside of each other.Once hydraulic pressure is introduced to the cylinder, the l...

Double ActingA cylinder in which fluid force can be applied in either direction to the moveable element. These cylinders are also classified as differential cylinders because of their unequal exposed areas during extend and retract. The difference in effective area is caused by the area of the rod that reduces the ...

Pneumatic cylinders rarely provide much more than a hundred pounds per square inch of pressure to the piston, whereas hydraulic cylinders are capable of anywhere from 1500 to 10,000 psi, which can be ten to hundred times the force of a pneumatic cylinder.

A ram-type cylinder is a cylinder in which a cross-sectional area of a piston rod is more than one-half a cross-sectional area of a piston head. In many cylinders of this type, the rod and piston heads have equal areas. A ram-type actuating cylinder is used mainly for push functions rather than pull. ...

A hydraulic cylinder is made up of 7 main components:Cylinder Barrel (Main, Body). The barrel is the cylindrical body of the cylinder. The barrel guides the piston and provides a sealing surface for the piston seal. The barrel is also the structural part of the cylinder that holds the ends in place.Cylinder Cap (Ba...

The function of hydraulic cylinder is to provide linear motion. It converts the fluid energy into mechanical energy (linear movement). Cylinders are broken down into two main categories: pneumatic and hydraulic. Pneumatic cylinders can be operated by several types of gases, however, compressed air is by far the mos...

A hydraulic cylinder is a device which converts fluid power into linear mechanical force and motion proportional to the effective cross-sectional area of the piston. Their output force, or motion, is in a straight line. Their work applications may include pushing, pulling, tilting, and pressing. Cylinder type and d...

The three most common hydraulic cylinder configurations are piston hydraulic cylinders, telescopic hydraulic cylinders and plunger hydraulic cylinders. Each cylinder design varies by the type of application as below: Piston hydraulic cylinders are the most common on the market and can be designed with welding (weld...

Many of the failures in a hydraulic system show similar symptoms: a gradual or sudden loss of high pressure, resulting in the loss of power or speed in the cylinders. In fact, the cylinder may stall under a light load or may not move at all. Often the loss of power is accompanied by an increase in pump noise, espec...

Side loadingSide loading is a very common hydraulic cylinder failure, which is caused from the cylinder being misaligned which creates an unparalleled force on the piston rod. Hydraulic cylinder is a linear motion product that supposed to operate strictly back and forth as well as cylinder is not supposed to play a...

Hydraulic cylinders take a significant part of the entire hydraulic system. They are mechanical actuators that provide the unidirectional force. Integration of hydraulic cylinders will eliminate the presence of levers and gears. Both mobile (front end loaders, hydraulic lifts, construction vehicles, tractors, auto ...

How to change hydraulic cylinders? In most times, a hydraulic cylinder can be repaired by changing out pistons or seals inside the cylinder. However, on rare occasions, you may need to replace the entire cylinder itself. If that situation arises, you will need to know ho...

Why do hydraulic cylinders start leaking? Why do hydraulic cylinders start leaking?Seals play a major role in hydraulic cylinders – they contain the fluid and prevent the leakage of fluid. The seals for a rod sealing system protect the reciprocating motion for the piston...

How to measure a hydraulic cylinder replacement? In order to measure and decide which hydraulic cylinder you need, first of all you would have to visually determine the type of hydraulic cylinder you try to replace. Here are the the main three types of hydraulic cylinder...
