Hydraulic Link Cylinder

A hydraulic link cylinder, or simply a hydraulic cylinder, is a mechanical actuator that uses an incompressible fluid (typically oil) to provide a linear, unidirectional force. Hydraulic link cylinder The hydraulic cylinder converts the pressure applied to the hydraulic fluid into linear motion to power machinery such as hydraulic presses, hydraulic jacks and hydraulic brakes. They are also used in construction equipment such as excavators, backhoes and tractors to operate the lift arm or bucket. In addition, they are used in material handling equipment such as forklift trucks and telehandlers to lift heavy loads.

The heart of a hydraulic cylinder is the cylinder barrel, which can be made of either a cold-drawn seamless tube or a drawn over mandrel (DOM) tube. Hydraulic link cylinder The cylinder barrel has a smooth inside surface, high tolerance, and is made to be durable in use.

Inside the cylinder is a piston with sliding rings and seals that separates the pressurized hydraulic fluid into two chambers: the bottom of the cylinder (cap end) and the rod-end head. Hydraulic link cylinder The piston extends from the cylinder's rod-end head when the hydraulic pressure is applied and retracts when the hydraulic pressure is removed. A hard-chromed piece of steel called a piston rod connects the hydraulic cylinder to the machine component doing the work.

The cylinder head, which is machined with grooves to fit elastomeric or metal seals and bearing elements, is attached to the piston. Hydraulic link cylinder The cylinder head contains the primary seal, the secondary seal, the buffer seal and the bearing elements. The cylinder head is attached to the cylinder rod using threads, bolts or nuts to transfer the linear movement.

Hydraulic oil is fed to the cylinder through the cylinder port and enters the head through the cylinder gland. Hydraulic link cylinder The cylinder head gland is fitted with a set of seals and bearing elements to prevent the pressurized hydraulic oil from leaking past the interface between the piston and the cylinder head. The gland can be easily removed and replaced by a new gland without any need for dismantling the entire cylinder.

The cylinder head and the gland are protected from the harsh conditions in which the cylinder is operated by a hardwearing surface coating such as Chrome (Nickel) plating, Lunac 2+ duplex, Laser Cladding or PTA welding. The cylinder rod is usually made of a strong material such as high-grade cold-rolled steel or stainless steel to resist corrosion. A regenerative cylinder control circuit is often used with this type of hydraulic cylinder. It consists of a valve and piping which, during the extension of the piston, conducts hydraulic oil from the piston side to the rod side of the cylinder instead of returning it back to the pump reservoir. This regenerative action increases the life of the hydraulic cylinder.
