Essential Parts Of Hydraulic Cylinders And Their Roles


These cylinders play a major role in most applications. Most auto parts and heavy machinery are easily operated using the principles of hydraulics. In addition, there are many other equipment and machines such as elevators, excavators, injection molding machines, bulldozers, and many other cars. They are the simplest form of machinery used to transmit effective power to many different machinery and automobiles. They are available in various types, including heavy-duty industrial cylinders, tie rod cylinders, front flange mount hydraulic cylinders, etc.

Essential Parts Of Hydraulic Cylinders

However, any production unit needs to understand the functions, operating systems, structure, and parts of the cylinder to benefit from the cylinder. A simple cylinder type generally consists of 5 different parts, including the barrel, piston, rod, gland, and end cap.

Piston: The piston is the inner part of the cylinder that pushes against the liquid. This is the essential part of the cylinder. Without a piston, hydraulic cylinders are considered cylinders only. The diameter of the piston is called the bore.

Rod: The rod is the part that connects the stuffing box and the piston of the cylinder. The diameter and hardness of the rod are very important for the hydraulic cylinders. On heavy-duty cylinders, the rod is stronger, reducing the chance of bending.

Maintenance On Pneumatic Cylinders

The pneumatic cylinder is one of the most important (and expensive) automation components because it is what moves/forces. However, maintaining a pneumatic cylinder can be laborious and time-consuming. Often this will involve sending the cylinder in to be cleaned, replaced with parts such as seals and others, assembled, and tested. This may take several days. So, in the case of large cylinders in critical operations, it is essential to plan for maintenance during scheduled shutdowns.

In case of failure, it usually becomes much quicker to change the cylinder. However, even when changing the cylinder, it is essential to identify the failure reason that may be linked to poor air quality or non-axial efforts to the cylinder axis.

Valve Maintenance

Pneumatic valves, when properly operated, will have a very high life cycle. Usually, a valve failure indicates a problem with the air or electrical signal if it is a solenoid valve.

Cylinders, Inc – Hydraulics & Pneumatics Service in Chicago for example helps you replace any valve, send the code, or even a photo of the valve to be replaced.


Under Pressure

Constantly monitor gauges. It is not good to supply air pressure above the specified, which is very common, especially in applications with smaller cylinders and pneumatic grippers.

Use quality parts

There is a wide range of pneumatic component manufacturers on the market, with a significant variation in quality and prices. Cheap can be very expensive, so it is essential to value the price, but with a guarantee and quality items.

Identify the best suppliers that can serve you in the following aspects:

  • Fast service to help with parts replacement
  • ample stock
  • Quality manufacturer brand
  • Meet delivery deadlines
  • Have experience and technical knowledge to help solve problems
  • Get competitive prices
