External seals on the piston rod fit tightly around the rod to prevent contaminants from entering the cylinder and mixing with the hydraulic fluid. Excavators are primarily made up of a #cylinders boom, a #bucket dipper, and a cab. Inside the hydraulic cylinder is a #rod, which is the inner part of the cylinder, and a #piston, which is at the end of the cylinder and allows the arm to move with the help of #Hydraulic fluid. If there was no fluid in the cylinder, the piston would fall to the bottom, but due to the nature of hydraulic fluid, its volume always remains constant.
Excavator Cylinder Function
Reduce downtime by using replacement excavator cylinders that are built to last. Even the most demanding applications and harsh environments are no match for our excavator replacement cylinders. Oil leakage as a result of frequently exceeding the hydraulic cylinder’s pressure range. The hydraulic oil cylinder will leak if the inlet and outlet pipe joints on the oil cylinder crack.
Though the mechanisms and principles of a hydraulic cylinder can be complicated (Pascal’s Law), you don’t need a master’s degree in mechanical engineering to understand how they work. River Valley Machine designs, manufactures, and distributes high-quality aftermarket accessories and repair parts for the world’s most popular skid-steer loaders and other… The piston’s wear ring is severely worn, causing friction between the piston and the cylinder liner and eventually straining the cylinder liner, piston, and seal. Oil leakage caused by flaws in the hydraulic cylinder block or cylinder end cover.
Working under the supervision of Mr. Navin Gupta has given me a lot of experience in this field. He never compromises on the quality of the facilities provided. Our knowledgeable staff will gladly assist you with any tractor, backhoe, dozer, or engine parts needs.
This article is part of the H&R Construction Equipment Parts knowledge base series, which is designed to speak informatively and passionately about heavy equipment industry topics. The series’ goal is to provide basic information to any and all inquisitive minds, from 10-year-old excavator enthusiasts to passionate parts tinkerers looking to learn more. Internal seals at all connections ensure that all fluid remains within the system. Internal seals around the piston allow the piston to move with less friction and wear while maintaining proper pressure on both sides of the piston. Fluid that is allowed to leak outside of the cylinder reduces power, as does fluid that is allowed to leak from either side of the cylinder’s chambers.
Our parts specialists are standing by to take your request for Excavator Boom Cylinders right now! When you call or email us with your request, we do our best to respond as soon as possible. The arm cylinder is attached to the boom and the arm and drives the arm up and down in a swinging motion.

To see the correct currency and shipping rates for your location. River Valley Machine continues to provide high-quality parts and aftermarket accessories at extremely low prices! Fits virtually any skid steer or compact tractor built after 1995 that has Quick-Attach. The top portion of a Bobcat® Bobtach is a common failure. OEM The material thickness is only 14″ – they simply wear thin, bend, and eventually break over time. When this happens, your attachments will fit loosely or fall off of your machine.
Cylinder Effects
It should be obvious that at the heart of heavy construction machinery is a slew of cylinders pushing and pulling away. The piston rod must leave the barrel and, with it, its hydraulic fluid bath on its way to pushing and pulling. When the piston rod is exposed to the atmosphere, it takes on new risks, such as erosion, impacts, lateral force, and even weather. The cylinder cap and head are located at the ends of the hydraulic cylinder. The cylinder head is attached to the piston rod, and both components are designed to contain cylinder pressure and connect to another component in a specific way to facilitate movement.
Please excuse my reach; the stick cylinder on this Kobelco excavator extends to over 20 feet. In some cases, cylinders work together, such as these excavator boom cylinders. They divide the heavy lifting of the boom, all of its attached components, and the load in the bucket. If one cylinder is insufficient, and two are still insufficient, three cylinders working together may be required. This cylinder triplet on a bulldozer allows for precise control of the blade.
Our excavator hydraulic cylinders are compatible with Komatsu, Hitachi, Kobelco, Sumitomo, Daewoo, Hyundai, and Volvo excavators, among others. We also provide OEM services based on customer technical drawings and samples. That concludes our brief introduction to cylinders. We hope you found it informative and entertaining.
